Larry David famously instituted a policy of "no hugging, no learning", meaning that the show must avoid sentimentality and moral lessons, and the characters must never learn or grow from their wrongdoings.

As Kramer (Michael Richards) became more popular, his entrance applause grew so prolonged that the cast complained it was ruining the pacing of their scenes. Directors subsequently asked the audience not to applaud so much when Kramer entered.

Jerry Seinfeld turned down an offer from NBC that would have made him $110 million for a tenth season of the show.

Larry David was quite volatile in meetings with NBC executives, and would often outright refuse to accept their notes and suggestions. He was eventually banned from attending the meetings.

Before the show was set to air, Jerry Seinfeld asked Jason Alexander what he thought their chances for success were. Alexander said he thought they "didn't have a chance". When asked why, Alexander responded, "Because the audience for this show is me, and I don't watch TV."

Michael Costanza, Jerry Seinfeld's friend after whom George is named, filed a $100 million lawsuit against Seinfeld, Larry David, and NBC, claiming invasion of privacy and defamation of character. Costanza claimed damages due to the show's alleged use of his likeness. The case was dismissed with the judges adding that the statute of limitations on the case had run out, as Costanza did not sue within one year of the show's debut in 1989.

Director Steven Spielberg once commented that while filming Schindler's List (1993), he got so depressed that he would watch tapes of this show's episodes to cheer himself up.

The night before the final episode, ABC aired an episode of Dharma & Greg (1997) in which the couple tries to have sex in public, because everyone will be indoors watching the "Seinfeld" finale.

When the final episode aired on May 14, 1998, the TV Land network honored the occasion by airing no programming in the show's timeslot. Instead, the network just showed a still photo of a closed office door.

It was originally intended that Elaine's (Julia Louis-Dreyfus) formidable father, famous author Alton Benes, of whom Jerry (Jerry Seinfeld) and George (Jason Alexander) are terrified, be a recurring character, but in an odd case of life imitating art, Lawrence Tierney really did frighten and intimidated the other cast members that it was decided he should never return.

During the original airing of the finale, MTV aired original cartoons that were specially timed to fit into the finale's commercial breaks, so that viewers could freely watch both of them and not worry about missing anything.

The Soup Nazi (Larry Thomas) is based on the actual owner, Al Yeganeh, of a take-out soup business in Manhattan on West 55th Street between Broadway and 8th Avenue. Just like in the sitcom, his soups were known for their excellent quality, but Yeganeh was also famous for the unusual way he treated his customers. Instead of calling him a Nazi, local patrons called him a terrorist, presumably because they knew Yeganeh was born in Iran, not Germany. Yeganeh was so angered by the episode (Seinfeld: The Soup Nazi (1995)), that he forbade the use of the "N word" in his restaurants. Even the slightest reference to this show would push his buttons (it can be seen in an interview he did with CNN). So when some cast members and writers from this show bravely visited the restaurant after the episode aired, Yeganeh claimed that the show had ruined his life.

Jerry (Jerry Seinfeld) says "Hello, Newman" 17 times in the entire series.

One of only three series in American history to rank number one in the ratings for its entire final network season. The other two were I Love Lucy (1951) and The Andy Griffith Show (1960).

Jason Alexander originally based his portrayal of George on Woody Allen, which is why he wore glasses. When he realized that George was actually based on Larry David, he began basing his performance on David's mannerisms.

Jerry Seinfeld was inspired to end the show after nine seasons by The Beatles, who broke up after nine years together.

The puffy shirt used in episode 5.2, Seinfeld: The Puffy Shirt (1993), is currently placed in the Smithsonian. A doll-sized replica was included with the fifth season DVD set.

John O'Hurley (Peterman) recalls attending a friend's 40th birthday party and being recognized at the buffet line. A man came up to him to say "that would be grounds for dismissal.", one of his J. Peterman lines. During their conversation, O'Hurley learned that this guy was not only a fan of Seinfeld but a fan of the real J. Peterman catalogue, too. He would actually read the over-the-top item descriptions to his wife in bed. He thanked O'Hurley for finally giving him a voice to use for the catalogue readings. The fan was none other than Tom Hanks.

In the episode where Elaine dates a man named Joel Rifkin (episode 5.9 Seinfeld: The Masseuse (1993)), she tries to have him change his name, since Joel Rifkin is also the name of a man involved in a notorious New York City murder case. One of the initial suggestions for a new name was O.J. This episode was shot in 1993, a year before O.J. Simpson was accused of murdering his ex-wife Nicole Brown Simpson and Ron Goldman.

Julia Louis-Dreyfus was pregnant while shooting part of this series. Her pregnancy was disguised with her carrying props to hide her changing body. This was parodied on The Nanny (1993), when the very-pregnant Lauren Lane mentioned them hiding Elaine "behind all these huge props" while standing in front of a poster with "Baby" on it.

The character of Cosmo Kramer was based on Kenny Kramer, a man who worked across the hall from co-creator Larry David. In a self-confessed move to cash in on the sitcom's popularity, Kenny Kramer formed the "Kramer Reality Tour", an officially-recognized New York City tour which visits the real-life locations often featured in the sitcom. In the 1997 season of this show, Cosmo Kramer's memoirs are published by J. Peterman as his own. Wanting to make the most of the situation, Cosmo Kramer starts a "Peterman Reality Tour", offering a tour of the real-life locations featured in the memoirs.

Though Larry David played George Steinbrenner, the actual George M. Steinbrenner III was filmed playing himself for use in an episode. However, the scene was never shown on the series. Steinbrenner did appear with Jason Alexander (in the part of George) in a 1996 promotional spot for MLB All-Star Game balloting.

Kramer's (Michael Richards) famous "I'm out of the contest!" moment was his one hundredth entrance into Jerry's (Jerry Seinfeld) apartment.

The model of the bike Jerry (Jerry Seinfeld) never rides, hanging in his apartment, changes throughout the series.

The apartment used for exterior shots of 129 West 81st Street, New York City, New York, is not actually in New York at all, but is 757 S. New Hampshire Avenue, Los Angeles, California.

Larry David based George Costanza on himself. Many of the situations into which George gets himself are based on David's real-life experiences. George was named after Jerry Seinfeld's friend Michael Costanza. George's middle name, Louis, was an homage to Lou Costello of The Abbott and Costello Show (1952), which was a major influence on this series.

Voted the number one top television series of all time, beating out number two, I Love Lucy (1951), and number three, The Honeymooners (1955), in the list of fifty shows chosen by TV Guide editors, April 2002.

The original script was called "Stand Up". It was to be a ninety-minute mockumentary about how a stand-up comedian writes his jokes based on his everyday life. It was to air in place of Saturday Night Live (1975) for one night. NBC liked the script so much that they decided to develop it into a pilot instead.

While they are waiting in the Chinese restaurant in episode 2.11 Seinfeld: The Chinese Restaurant (1991), Jerry (Jerry Seinfeld) lists the many people that will be getting phone calls as a result of him being seen there. One of the included people was his sister. His sister never appeared on the show, nor is she ever referred to again.

Kramer's (Michael Richards) line "These pretzels are making me thirsty" is an homage to Jeff Goldblum and his one and only line in Annie Hall (1977), a Woody Allen film. Goldblum's line is famous in movie history for his delivery.

Jerry (Jerry Seinfeld), George (Jason Alexander), and Kramer (Michael Richards) each had alter-egos that they used on occasion. Jerry's was Kel Varnsen, George's was Art Vandelay, and Kramer alternated between Dr. Martin Van Nostrand and H.E. Pennypacker.

The restaurant exterior belongs to Tom's Restaurant, which is the same restaurant that was immortalized in the Suzanne Vega song "Tom's Diner". It is near the Columbia University campus in Manhattan at West 112th Street and Broadway.

Larry David was very adamant that every character of the lead quartet had a storyline in each episode, and he even charted it out on the writers' room, to keep close track of the plots and screentime.

Kramer's (Michael Richards) wardrobe of mostly 1960s and 1970s clothing was not intended to make him into retro fashions, so much as to suggest that he hadn't bought clothes in several years. The pants, in particular, were always about an inch too short in order to stress this. In later seasons, appropriate clothing became increasingly difficult for producers to find, due to the combination of it getting older and older, as well as the extreme popularity of Kramer as a character, forcing them to have tailors personally make Kramer's clothing out of retro fabrics. Often, they would create numerous back-up copies of the clothing in case it was damaged during the physical comedy.

In the episode where George (Jason Alexander) thinks someone stole his glasses from the gym locker room (episode 5.3 Seinfeld: The Glasses (1993)), he is eating a bag of Rold Gold pretzels. At the time, Jason Alexander was a spokesman for the product.

Lee Garlington was originally supposed to be a member of the cast, as Claire, the coffee shop waitress who gave Jerry (Jerry Seinfeld) and George (Jason Alexander) friendly advice. She appeared in the pilot episode, Seinfeld: Good News, Bad News (1989). But when the show was picked up, her character was dropped. According to Jason Alexander, Garlington offended Larry David by re-writing her lines.

A running gag in the show is that Jerry (Jerry Seinfeld) can't act. This was actually a real concern for the shows producers. To weigh up for this they needed strong supporting actors, hence Jason Alexander, who previously had been an actor on Broadway.

An episode titled "The Bet", in which Elaine (Julia Louis-Dreyfus) buys a gun from Kramer's (Michael Richards) friend, was written for season two. It was not filmed, because the content was deemed unacceptable, and was hastily replaced by season two, episode four, Seinfeld: The Phone Message (1991).

In early versions of the pilot script, George (Jason Alexander) was originally written as a fellow stand-up comedian named "Bennett".

The show's often-repeated phrase, "Yada, yada, yada", was ranked number one in TV Guide's list of TV's 20 Top Catchphrases (August 21-27, 2005 issue).

Many plots of the early episodes were completely based on the episode writer's real-life troubles, including season one, episode three, Seinfeld: The Robbery (1990), season two, episode three, Seinfeld: The Jacket (1991), season two, episode eleven, Seinfeld: The Chinese Restaurant (1991), season three, episode seven, Seinfeld: The Cafe (1991), season three, episode nine, Seinfeld: The Nose Job (1991), and many others.

Jerry's (Jerry Seinfeld) girlfriend's infamous "man hands" in episode 8.3, Seinfeld: The Bizarro Jerry (1996), were actually those of James Rekart.

Elaine (Julia Louis-Dreyfus) was not originally part of the series. During development, NBC expressed concern that the series would be too male-centric, and became insistent on including a regular female character. The network was also said to make the casting request as a condition for picking up the series.

Patrick Warburton was unable to play his recurring role of David Puddy in the seventh and eighth seasons, due to his commitment to Dave's World (1993).

In one of the episodes, Jerry (Jerry Seinfeld) is walking down the street with one of his buddies, and in the background, there's a building with a sign on it that reads "Kal's Signs". Jerry Seinfeld's real-life dad's name is Kal, and he made signs for a living.

Steve Vinovich, Larry Hankin, and Tony Shalhoub were considered for the role of Kramer. Hankin later played Kramer in the show within the show in season four, episode twenty-three, Seinfeld: The Pilot (1993).

Throughout the series, there are numerous references to Kramer's (Michael Richards) friend Bob Saccamano, but the character is never seen.

The character of Lloyd Braun (George's childhood neighbor, and rival) was played by two different actors, first Peter Keleghan then, four years later, Matt McCoy.

Larry David was the original voice of Newman in season two, episode seven, Seinfeld: The Revenge (1991), but Wayne Knight redubbed the voice for syndication.

Jerry Seinfeld received five Emmy Award nominations for Outstanding Lead Actor in a Comedy Series, but never won.

The show introduced a character, "Crazy" Joe Davola, the name of an ABC executive producer.

In real life, Jason Alexander does not wear eye glasses, and the ones he wore as George were props.

ABC Entertainment executive Lloyd Braun lent his name to a character appearing in three episodes, season five, episode seven, Seinfeld: The Non-Fat Yogurt (1993), season seven, episode ten, Seinfeld: The Gum (1995), and season nine, episode three, Seinfeld: The Serenity Now (1997), and is an old childhood neighbor and nemesis of George Costanza (Jason Alexander).

Season three, episode seven, Seinfeld: The Cafe (1991), was the first episode to have applause by the studio audience as Kramer (Michael Richards) entered. Interestingly, it happened when Kramer entered the Dream Café rather than Jerry's (Jerry Seinfeld) apartment.

Jason Alexander has stated that, in addition to Larry David, his performance as George was also inspired by Jackie Gleason's performance as Ralph Kramden in The Honeymooners (1955).

Elaine, played by Julia Louis-Dreyfus, is loosely based on Carol Leifer, a friend of Jerry Seinfeld's, whom he also used to date. She is also based on model Susan McNabb, who was Seinfeld's long-time girlfriend, and Monica Yates, whom Larry David dated.

Rosie O'Donnell, Patricia Heaton, Mariska Hargitay, Jessica Lundy, Amy Yasbeck, and Megan Mullally auditioned for the role of Elaine.

Danny DeVito, Nathan Lane, David Alan Grier, Larry Miller, Kevin Dunn, and Brad Hall were considered for the role of George.

Kramer (Michael Richards) did not appear in season two, episode eleven, Seinfeld: The Chinese Restaurant (1991) and season three, episode three, Seinfeld: The Pen (1991), and George (Jason Alexander) also did not appear in season three, episode three, Seinfeld: The Pen (1991).

Kramer's (Michael Richards) first name was originally going to be "Conrad". This was planned to be revealed in a season two episode titled "The Bet", written by Larry Charles. But the episode was scrapped due to its controversial storyline, in which Elaine (Julia Louis-Dreyfus) buys a gun. Kramer's first name was finally revealed to be "Cosmo" in season six, episode eleven, Seinfeld: The Switch (1995).

One of the first successful sitcoms to have extensive segments filmed outdoors.

In a season three episode, George can be seen wearing a baseball shirt that says "Broadway Bound". Jason Alexander appeared in a play of this name by Neil Simon during its original New York City run.

In the first show, Seinfeld: Good News, Bad News (1989), Kramer's (Michael Richards) last name was Kessler. Jerry (Jerry Seinfeld) is heard saying Kessler exactly the same way as he does Kramer. This was because Kenny Kramer would not allow his name to be used on the show, unless he was allowed to play Kramer. Eventually Kenny Kramer's list of demands were met, and the name Kramer was used.

Morty Seinfeld (Jerry's father) was originally played by Philip Bruns for one episode, then by Barney Martin for the rest of the series run.

Throughout the run of the series, Kramer (Michael Richards) rarely says "Yes". Nearly all of his positive responses are slang variations ("Yup", "Yeah!", "Giddyup", et cetera). Six episodes where he does actually say "Yes" are: Season three, episode thirteen, Seinfeld: The Subway (1992) Season four, episode five, The Wallet Part 1, Season five, episode two, Seinfeld: The Puffy Shirt (1993) Season five, episode four, Seinfeld: The Sniffing Accountant (1993) Season eight, episode eleven, Seinfeld: The Little Jerry (1997) Season eight, episode seventeen, Seinfeld: The English Patient (1997).

With the exception of episode 1.3, Seinfeld: Male Unbonding (1990), and episode 6.14, Seinfeld: Highlights of a Hundred (1995), every episode started with the word "The".

Robert Schimmel auditioned for the role of George.

We learn Kramer is a military veteran in episode 9.14, Seinfeld: The Strongbox (1998). Michael Richards, who plays Kramer, is also a veteran, having been drafted in 1970 and serving for two years in Vietnam.

During the entire series run, Kramer's (Michael Richards) source of regular income is never revealed.

Elaine Benes, played by Julia Louis-Dreyfus, was named after Terry Benes, a friend of Larry David.

At Jerry Seinfeld's high school, Massapequa High School on Long Island, there was a teacher named Mr. Bevilaqua, he was the wrestling coach there. In one of the episodes, Jerry had a race that was officiated by Mr. Bevilaqua.

As Larry David states on the DVD, the character of Elaine's father, the gruff war vet and author Alton Benes, was based on the late writer Richard Yates, who was the father of his former girlfriend Monica Yates, and author of the novel "Revolutionary Road".

Phil Morris planned to star in a spin-off as Jackie Chiles, but the project was stalled.

Although Jerry's (Jerry Seinfeld) cousin Jeffrey is mentioned several times throughout the series (always by Uncle Leo (Len Lesser)), he never appeared on the show (although he does appear in a deleted scene on the DVDs).

Episode 1.0, Seinfeld: Good News, Bad News (1989), was watched by nearly 11% of American households, and received generally favorable reviews from critics, who reacted with disappointment that NBC did not order a first season. Convinced that the show had potential, and supported by the positive reviews, NBC executive Rick Ludwin managed to convince his superiors to order a four-episode first season by offering a part of his personal budget in return.

The first time Elaine's catchphrase of "Get Out" is introduced is in episode 2.5, Seinfeld: The Apartment (1991). Julia Louis-Dreyfus actually does that shove in real life and the moment was not in the original script.

Bob Balaban played an NBC network executive who approved a sitcom pilot to be called "Jerry". Balaban was chosen because of his resemblance to NBC executive Warren Littlefield, the man who allowed Jerry Seinfeld and Larry David to produce this show's pilot. Balaban also played Littlefield in The Late Shift (1996).

Elaine's (Julia Louis-Dreyfus) dancing in episode 8.4, Seinfeld: The Little Kicks (1996), was inspired by the Saturday Night Live (1975) boss Lorne Michaels. Seinfeld writer Spike Feresten started his career as a receptionist at SNL and has said that at a SNL after-party, he saw Michaels dance "as if he'd never seen another human being dance before" and that he "heaved and gyrated to a rhythm only he could feel."

Tony Shalhoub auditioned for the role of Kramer, and many years later Michael Richards was considered for the title role on Monk (2002). Richards passed and Shalhoub took the role. Richards won three Emmys for playing Kramer, while Shalhoub also won three Emmys for playing Monk.

In his autobiography, Paul Shaffer claimed to have turned down the role of George. He was offered the part due to his resemblance to Larry David, upon whom the character is based.

Jerry (Jerry Seinfeld) and George (Jason Alexander) mention having siblings seasons 2 and 3, but neither are ever seen or mentioned again.

It was originally planned for Elaine (Julia Louis-Dreyfus) to be an eye doctor.

Julia Louis-Dreyfus, Jason Alexander, Michael Richards and Jerry Seinfeld had a superstitious ritual they completed before the taping of every episode. They gathered in set of Jerry' bathroom and placed their hands on top of each others and as they released them they would all make a quick, very loud yelping sound. The group called this "The Circle of Power." This gesture made it into a couple of episodes, including episode 4.11 Seinfeld: The Contest (1992).

In addition to Jerry (Jerry Seinfeld) having a sister who is only mentioned once (in season two, episode eleven, Seinfeld: The Chinese Restaurant (1991)), George (Jason Alexander) has a brother who is mentioned only twice in the series: season three, episode fifteen, Seinfeld: The Suicide (1992), (his brother impregnated a woman named Pauline) and season three, episode six, Seinfeld: The Parking Garage (1991) (George's father, mother, and brother never pay for parking). Elaine (Julia Louis-Dreyfus) has a sister, Gail, who she visits in St. Louis, and who she calls after she sends Gail's son her exposed nipple Christmas card. Elaine also mentions a brother-in-law (presumably Gail's husband) in season two, episode four, Seinfeld: The Phone Message (1991) (he blurted out secret business information on an answering machine).

In season four, episode six, Seinfeld: The Watch (1992), Elaine (Julia Louis-Dreyfus) is asked by Joe Davola (Peter Crombie) if he knows her from somewhere, and she answers with a joke that he probably recognizes her because her face is sculptured on Mount Rushmore, alongside the U.S. Presidents, instead of Roosevelt's face. In 2015, a poster was released for the fourth season of Veep (2012) that showed the face of Selina Meyer (Julia Louis-Dreyfus) sculptured on Mount Rushmore, but it appeared instead of Jefferson's face.

Newman (Wayne Knight) was originally written as the African-American son of Jerry's (Jerry Seinfeld) landlord. William Thomas Jr. was cast, and a scene featuring him was filmed, but it was deleted. Tim Russ also auditioned for the role.

For awhile, NBC stunted with having an interconnected storyline, or character crossover between their New York City set sitcom block which aired on Thursday nights. Seinfeld was the only one of the shows which refused to take part.

In Seinfeld: The Bizarro Jerry (1996) during the scene in Kevin's (Tim DeKay) apartment, you can see "Bizarro Superman" in the background.

Heidi Swedberg (Susan) initially thought she was going to be playing Kramer's (Michael Richards) love interest. It wasn't until midway through the fourth season that she realised it would be George (Jason Alexander), not Kramer.

In the series finale, Kramer (Michael Richards) suggests that he, George (Jason Alexander), Elaine (Julia Louis-Dreyfus), and Seinfeld (Jerry Seinfeld) do a musical such as "Bye, Bye, Birdie" or "My Fair Lady". Jason Alexander, who plays George, starred in Bye Bye Birdie (1995) as Albert Peterson.

Kramer's (Michael Richards) first name of Cosmo was not revealed until the show's sixth season. The revelation, and some promotional hype surrounding it, was criticized by some at the time for being too gimmicky, or unnecessary.

Jerry Stiller played George's dad. Ben Stiller (Jerry's real-life son) is married to Christine Taylor, who guest-starred on the show as Jerry Seinfeld's girlfriend.

Jerry's (Jerry Seinfeld) apartment number switches from 411 to 3A to 5A. In earlier episodes, where the whole exterior of Jerry's building is visible, his apartment is clearly on the third floor. But in one episode, Jerry suggests that a bus stop on the corner is ten floors down.

In season three, episode six, Seinfeld: The Parking Garage (1991), George (Jason Alexander) is leaning up against a car with the license plate BIF725.

Director Tom Cherones and writer Larry Charles both left the show after season five.

In retrospect, most critics and fans agree that the episode "The Chinese Restaurant" in Season Two is the first episode to truly embody the concept of "a show about nothing". Interestingly, the NBC execs overseeing the series hated the episode exactly because nothing happened and held it back to broadcast towards the end of the season believing that the episode was weak.

Initially there was a plan to turn Kramer (Michael Richards) into a millionaire, but this was discarded. Had it gone ahead, it would've explained how he was able to live so comfortably without having steady employment.

In Seinfeld: Male Unbonding (1990), the character Elaine is sleazily hit on by Jerry's unstable "friend", Joel (Kevin Dunn ). Twenty-two years later, Kevin now plays the role of Ben Cafferty in the show Veep (2012), as an advisor to the title character Selina Meyer, played by Julia Louis-Dreyfus.

Seasons 1, 2, and 8 are the only ones that don't have a two-part episode.

Bob Sacamano is a fictional friend of Kramer (Michael Richards). He is never seen but is the source of many bizarre anecdotes. Larry Charles has stated that Sacamano was a real-life friend, although the two fell out shortly after the character was first introduced. Throughout the course of the series he was referenced in the following episodes: 2.8 Seinfeld: The Heart Attack (1991) (due to malpractice in a hernia operation now sits in a chair by the window repeating "My name is Bob") 3.2 Seinfeld: The Truth (1991) (was once in a mental institution where electroshock therapy had no effect) 3.16 Seinfeld: The Fix Up (1992) (works in a condom factory & gives Kramer defective condoms 5.3 Seinfeld: The Glasses (1993) (once contracted rabies) 7.19 Seinfeld: The Calzone (1996) (once was Kramer's house guest for a year & a half) 8.6 Seinfeld: The Fatigues (1996) (throws a party but Elaine gets the invitation late) 8.8 Seinfeld: The Chicken Roaster (1996) (once sold replica Russian hats made of nutria in Battery Park) 8.14 Seinfeld: The Van Buren Boys (1997) (Kramer is on the phone with him when he realises he has to return a pair of pants, but while wearing them on the way to return them, falls into a puddle, ruining them) 9.15 Seinfeld: The Wizard (1998) (Bob's father provides poorly-made "Willard" tip calculators) 9.20 Seinfeld: The Puerto Rican Day (1998) (made a fortune through coming up with the idea of the rubber band for toy paddles with the ball & rubber band)

When Jerry Seinfeld performed his series of I'm Telling You For The Last Time concerts at the Bensonhurst Theatre in 1998, a small group of protesters turned up across the street every night condemning him for doing episode 9.20, Seinfeld: The Puerto Rican Day (1998). At one point, security had to be increased because of death threats.

During the sixth season NBC executives shared the original test results for the pilot episode with the supporting cast for the first time. The reviews from test audiences in late October 1989 were less than encouraging. They thought George (Jason Alexander) was a "loser" and a "wimp", that Jerry's (Jerry Seinfeld) everyday life was "boring" and his character "powerless", "dense" and "naive" and that Kessler (Kramer's original name) (Michael Richards), although sometimes "mildly amusing", was also underwhelming. They found the story lines a distraction from the stand-up segments which was the only part those familiar with Jerry's brand of comedy liked. Their overall view of the performance of that first show: "weak".

That show was described as Woody Allen meets The Wonder Years (1988). It lasted 6 shows. The renamed 'Seinfeld' lasted 9 years.

Jerry Seinfeld drew some of his material from Laurel and Hardy (Stan Laurel & Oliver Hardy), but has always maintained Abbott and Costello (Bud Abbott & Lou Costello) were the biggest influence on him.

Only one consistent trait of Kramer's (Michael Richards) character remained after the pilot. His constant appearances in Jerry's (Jerry Seinfeld) apartment. His dog mysteriously disappears, he's no longer agoraphobic, his Reverend Jim mannerisms were dropped and his hairstyle changed dramatically.

Any time Kramer (Michael Richards) supports "anti-authority" views, that's the work of Larry Charles who does believe in those "alternate truths".

One summer, Jerry Seinfeld and some of the writing staff would go outside to hit baseballs in the CBS Radford Studios parking lot while in pre-production. There weren't many cars in the lot at the time so it wasn't a big deal. But one day, a ball crashed through the window of one such parked car. Seinfeld found out that the car belonged to Alexandra Wentworth who was later cast as Sheila, AKA "Schmoopie", in episode 7.6 Seinfeld: The Soup Nazi (1995). Jerry paid for the damages.

Over the phone, Berg convinced Tays to go to the Oscars with him. (He was writing jokes for the ceremony one year.) Unfortunately, when he went to pick her up he found out she had a boyfriend, a photographer who wasn't too thrilled to see him. Tays had neglected to tell him about that on the phone.
