After Phil Hartman was murdered, the various characters he played, such as lawyer Lionel Hutz, and actor Troy McClure, were retired, rather than re-cast. However, they continued to appear silently in crowd scenes. Season ten, episode three, "Bart the Mother" (September 27, 1998) was his final voice performance.

According to a Simpson family tree designed by Matt Groening, Mr. Burns is a distant relative of Homer. Further, it's also revealed at the end of season twenty-one, episode thirteen, "The Color Yellow" that Grandpa Simpson's great-grandfather was black, making him 1/8 black, so Homer is 1/16 and Bart, Lisa, and Maggie are 1/32.

This is the longest running prime-time comedy series, as well as the longest-running prime-time animated series, in U.S. television history.

In season three, episode fourteen, "Lisa the Greek", Lisa, angry at Homer for tricking her into helping him gamble on football, makes a bet that if she loves him, the winner of the Super Bowl will be the Washington Redskins, and if she doesn't, the Buffalo Bills would come out on top (Washington won). Actually, when the show premiered just before the Super Bowl, those two teams were squaring off in Superbowl XXVI, and Washington came out on top 37-24. Over the next three years, FOX made it a tradition to air the episode just before the Super Bowl, and change the dialogue, so that the teams would include whatever teams were playing that year. According to the DVD commentary, Lisa accurately picked the winning team every single year.

The main characters were given a yellow coloring to attract the attention of channel hoppers.

Homer's e-mail address is

One of Cletus' kids is named Crystal Meth.

Elizabeth Taylor, Susan Sarandon, Alec Baldwin, Mark Hamill, Steve Buscemi, James Caan, Ricky Gervais, and Joe Mantegna are the only guest actors to play both themselves and a fictional character on the series.

Homer (Dan Castellaneta) is the only character to have dialogue in every episode. Marge (Julie Kavner) and Lisa (Yeardley Smith) have also appeared in every episode, but Marge did not deliver any dialogue in season four, episode twenty-two, "Krusty Gets Kancelled", and Lisa did not deliver any dialogue in season twenty-one, episode eighteen, "Chief of Hearts". Bart (Nancy Cartwright) did not appear in season twenty, episode twenty, "Four Great Women and a Manicure".

A television critic titled his article "Worst Episode Ever!" after watching a late 1990s episode, and criticized the show's writing. In the later seasons, there are many episodes in which the Comic Book Guy criticizes a character by saying "Worst episode ever!" and "Worst (action) ever!" in reference to the television critic's article.

The primary cast all have agreements in their contracts that hold them to doing three movies based on the show in the future.

The animation takes anywhere from six to nine months for each episode.

Characters' full names: Lisa Marie Simpson, Bartholomew JoJo Simpson, Margaret Evelyn Simpson, Marjorie Jacqueline Bouvier Simpson, and Homer Jay Simpson.

Comic Book Guy is based on Matt Groening himself: "He's the way I think I look to other people."

Although it was believed that Dr. Marvin Monroe was killed off in 1995 (as his tombstone can be seen in the Springfield cemetery), he reappeared in season fifteen, episode ten, "Diatribe of a Mad Housewife", in which he tells Marge that he has been "very sick". The real reason for Monroe's relative absence in the series was because he became too much of a strain on Harry Shearer's voice.

Except when it's combed, Bart's hair always consists of nine points.

In the scripts, Homer's "D'oh" is written as "(ANNOYED GRUNT)", Marge's disapproving murmur is written as "(FRUSTRATED MURMUR)", and Professor Frink's mumblings are written as "(FRINK NOISE)".

The blue and red discrepancy of Bart's shirt is referenced in one episode. Homer holds out Lisa (who wears a red dress) to tease a bull, then, thinking that he can placate the bull with something blue, he reaches for Bart, only to find him wearing his red shirt. He asks, "Where's your blue shirt?", to which Bart replies that he doesn't have one.

As in most cartoons, the characters have only four fingers on each hand, except God, who always has five. However, in what is probably a mistake, God has four digits during Homer's dream at the end of season four, episode three, "Homer the Heretic".

The creators jokingly insist that they have parodied Citizen Kane (1941) so much (fifteen times as of 2018 to be exact), that one could re-create the entire film solely from Simpsons clips. They also have made the same claim about The Godfather (1972) and The Godfather: Part II (1974).

Sideshow Bob is voiced by Frasier (1993) star Kelsey Grammer. In season eight, episode sixteen, "Brother from Another Series", Cecil, Sideshow Bob's brother, is featured, and is voiced by David Hyde Pierce, who played Frasier's brother Niles. Cecil also mentions Maris, Niles' never-seen wife, which is said ironically, since Bart is covering Cecil's eyes. They later completed the joke in season nineteen, episode eight, "Funeral for a Friend", in which Dr. Robert Terwilliger, Sr., father to Bob and Cecil, is voiced by John Mahoney, who played Frasier's father.

Bender, the robot from Futurama (1999), appeared in season fourteen, episode three, "Bart vs. Lisa vs. the Third Grade", and season eleven, episode fifteen, "Missionary Impossible", with other FOX Network characters. He made a speaking appearance in season sixteen, episode fifteen, "Future-Drama", as well as season twenty-six, episode six, "Simpsorama".

Milhouse has been cursed with a nefarious name. "Milhous" was Richard Nixon's middle name (spelled differently on this show) and Miss Leslie Van Houten was a member of the Charles Manson family. She was one of those who were convicted in the LaBianca murders. His middle name, "Mussolini", references Italian fascist dictator Benito Mussolini.

Bart's anonymous prank calls to Moe were inspired by "The Tube Bar Recordings", tapes of actual prank calls to Louis "Red" Deutsch, a New Jersey bartender famous for his violent temper (the pranksters, John Elmo and Jim Davidson, got the idea to prank him one day when, while passing his bar, they saw him beating up one of his customers for not drinking fast enough). Louis "Red" Deutsch would unfailingly respond to the prank calls with a stream of cursing, abuse, and threats. Bart's prank calls became less frequent after the first seasons, simply because the writers had a hard time coming up with new ones.

In one episode, a letter to Mr. Burns from the Simpsons does not show the state in which the Simpsons live, but reads Mr. Burns as living in Springfield, New Jersey.

Lionel Hutz says he got his law degree from Princeton. Although most Ivy League schools offer a law degree, Princeton does not, which helps confirm that he is phony.

Channel Ten, the Australian television network that airs this show in Australia, reportedly paid $25,000 per episode. Following a change of network ownership in 2017, FOX terminated its agreement with Ten, ending a 26 year relationship in Australia.

Donald Sutherland, who guest starred on season seven, episode sixteen, "Lisa the Iconoclast", appeared in The Day of the Locust (1975), where he played a character named Homer Simpson.

The show repeatedly makes fun of the FOX Network, which airs the show.

In the opening credits, the cash register shows $847.63 when Maggie is "scanned" (figure was taken from a survey (found by Matt Groening) done at the time that said that this was the average monthly cost of caring for a newborn baby, food, clothes, health, et cetera). But during The Simpsons spin-off episode, the 138th Episode Spectacular (hosted by Troy McClure) the credit sequence is paused and the machine is shown to read "NRA 4EVER".

Matt Groening based the character Bart Simpson on the title character in Dennis the Menace (1959), which he watched as a child, but was disappointed that Dennis was not as mischievous as he was in the comic strip.

Nancy Cartwright, voice of Bart, first tried out for Lisa's voice with her Bart voice.

Throughout the run of the series, a cawing crow is heard in nearly every establishing shot of the Springfield Nuclear Power Plant.

Groundskeeper Willie's father was hanged for stealing pigs.

The official city motto for Springfield is "Corruptus in Extremis", was invented to sound like Latin, but can be best described as "Latin gibberish". The show's translation for it is "Corrupt to the Extreme".

The telephone number at Moe's Tavern is apparently 764-8437, or "SMITHER", revealed when Mr. Burns tries to call Smithers but does not know his phone number. Naturally, SMITHER was his only guess: season seven, episode seventeen, "Homer the Smithers".

Mayor Quimby is based on John F. Kennedy.

Cletus (The Slack Jawed Yokel) and Brandine's children are named Tiffany, Heather, Cody, Dylan, Dermot, Jordan, Taylor, Brittany, Wesley, Rumer, Scout, Cassidy, Zoe, Chloe, Max, Hunter, Kendall, Caitlin, Noah, Sasha, Morgan, Kyra, Ian, Lauren, Q-Bert, Phil, Rubella, and Condoleezza/Cory McDowell Marie, and Crystal Meth.

Celebrities have been known to be so eager to make a guest appearance on this show that they'll even play themselves in an unflattering light. For instance, Jasper Johns played himself as a kleptomaniac, Gary Coleman played himself as a pathetic has-been, and Tom Arnold played himself as an obnoxious non-talent who gets fired into the sun for being such a bad actor.

Several characters in prison have the number 24601. That same prisoner number was Jean Valjean's in Victor Hugo's nineteenth century novel "Les Misérables".

Krusty the Klown's real name is revealed as Herschel Schmoikel Krustofski and Herschel Pinkus Yerucham Krustofski in different episodes.

The giant stone head in the Simpson basement (originally given as a thank-you gift for Bart donating blood to save Mr. Burns' life by blood transfusion in season two, episode twenty-two, "Blood Feud") is named Xtapolopacetl. That episode also revealed that Mr. Burns and Bart Simpson have the same blood type.

For a short period of time, the show was dubbed to Swedish in Sweden, but after receiving mountains of hate-mail, the network brought back the original show. The show started out dubbed in Dutch in The Netherlands, but when it was realized that adults did not like the dubbing, and children did not get the jokes mostly directed towards a mature audience, the original version was aired.

Hank Azaria said that he adopted his characters' voices from celebrities and people he has met. Among others, Chief Wiggum's voice is based on Edward G. Robinson, Lou's on Sylvester Stallone, and Comic Book Guy's on Hank Azaria's roommate in college.

The website that Homer created with false "dirt" on many of the citizens was able to be accessed as While the website still exists, it appears to be identical to

The original voice of Homer on The Tracey Ullman Show (1987) and the beginning of the first season was inspired by Walter Matthau, as the original sketch of Homer had a large overbite. However, Dan Castellaneta dumbed him down and said "my jaw would go out, my neck would go in, and then my I.Q. would drop about seventy points."

Ralph Wiggum was named after Ralph Kramden on The Honeymooners (1955) because the character was intended to be a loudmouthed child version of Homer. He originally was not Chief Wiggum's son. Chief Wiggum had a boy with blue curls. It wasn't until later that Ralph and his mom became part of the Wiggums. The boy with blue curls never appeared again. It was hinted at in season four, episode one, "Kamp Krusty" that Ralph was Chief Wiggum's son when Ralph answered to the name Wiggum during mail call. It wasn't until season four, episode fifteen, "I Love Lisa", that it was explicitly stated.

The salesman character Gil, who can't catch a break, was based on the character "Shelley Levene", played by Jack Lemmon in Glengarry Glen Ross (1992). It is also believed that Gil was based on Al Bundy from Married with Children (1986).

The Itchy & Scratchy cartoons are animated shorts which are part of the Krusty the Klown Show. In a way, these cartoons are analogous to this show, as this show originally started as thirty-second animated shorts which were part of The Tracey Ullman Show (1987).

Several recurring characters are spoofs for former or current celebrities: Arnie Pye: Ernie Pyle. Bumblebee Man: Roberto Gómez Bolaños (based on his Chapulin Colorado character) Drederick Tatum: Mike Tyson Judge Constance Harm: Judge Judy Sheindlin (Judge Judy) Rainier Wolfcastle: Arnold Schwarzenegger. This is made obvious in season fourteen, episode nine, "The Strong Arms of the Ma", presumably because the motif of that episode is bodybuilding.

Kang and Kodos (the aliens) are named for two Star Trek (1966) characters. In season three, episode seven, "Day of the Dove", Kang was a Klingon warrior, and in season one, episode thirteen, "The Conscience of the King", Kodos was an Adolf Hitler-like mass murderer.

The show grew from thirty-second segments that aired between comedy sketches on The Tracey Ullman Show (1987).

The many deaths of Hans Moleman: Forced off the road by Homer; flies off a cliff. Otto runs his AMC Gremlin off the road; his car stops narrowly missing a tree and then explodes anyway. His thick eyeglasses act as a magnifying glass and set him on fire. Is executed in Springfield after Homer eats his last meal. Burns, on an ether-induced hallucination, drills into Moleman's head thinking he's the Lucky Charms leprechaun. Engulfed by an anti-escape orb as Marge escapes from the Movementarians. Blown up by an explosive éclair meant to poison Homer. Knocked out by Homer in jail with a book. (possible death) The French neutron bomb Springfield, presumably killing Hans along with most everyone else. Hauled away by thugs at the retirement home when he makes a comment about the senior-edited Gone with the Wind (1939) they are watching. (he is possibly killed) Seen trapped in the phone booth in the bird sanctuary (which becomes a parody of The Birds (1963)). We don't see his death, but if you've seen The Birds (1963), you know his fate is sealed. Drowned in quicksand in season twelve, episode twenty-one, "Simpsons Tall Tales". Accidentally run over by Homer at the end of season thirteen, episode two, "The Parent Rap". In season two, episode three, "Treehouse of Horror", when Ned predicts Moleman's death, Ned saves Moleman, but then drops him into a manhole where there are lots of crocodiles.

As part of the many running jokes in the series, the location of the fictitious town of Springfield is never revealed. Whenever they locate the town on a map, for instance, we never see the map. Whenever someone says it out loud, the sound is muffled or masked by noise. The capitol of the state in which Springfield is located is simply called "Capitol City", which eliminates Illinois. In the "Behind The Music" episode, the state is mentioned, but there are several versions of the show, each with a different state name (including Kentucky and Missouri), to keep the not-revealing-the-location-of-Springfield joke going.

This is one of those series that doesn't have a specific first episode. The first episode created was season one, episode thirteen, "Some Enchanted Evening" (pushed to the end of the first season because scenes were being re-animated). It was first aired on May 13, 1990. The first broadcast half hour was season one, episode one, "Simpsons Roasting on an Open Fire" (aired December 17, 1989).

Apu was also based on Peter Sellers in The Party (1968), and was named after the title character in Satyajit Ray's Apu trilogy.

Springfield's zip code is 80085. In season twenty-one, episode twenty-one, "Moe Letter Blues", Moe states that he moved to Springfield because the zip code spells the word "BOOBS". The U.S. Postal Service website reports that there is no zip code 80085. However, the reverse (58008) which would spell "BOOBS" if turned upside down, happens to be the zip code of the tiny town of Barney, North Dakota. If the zip code 80085 did exist, it would be located somewhere in Colorado. All the actual zip codes from 80001 through 80049 are in Colorado, with zips 80050-80099 not being used.

In one episode, the Simpsons' phone number is given as (939)-555-0113. The area code 939 is one of two area codes for Puerto Rico.

Homer and Bart converted to Catholicism in season sixteen, episode twenty-one, "The Father, the Son, and the Holy Guest Star", Lisa converted to Buddhism in season thirteen, episode six, "She of Little Faith", and Marge and Maggie belong to Reverend Lovejoy's church, whose denomination would later be identified as "The Western Branch of American Reformed Presbo-Lutheranism" in the same one where Homer and Bart converted.

The Simpsons live on Evergreen Terrace. Early in the show's life the house number was given differently a few times (including 1094), but in later episodes the address settled down to 742 Evergreen Terrace.

When appealing to Danny Elfman for the perfect theme song, Matt Groening gave him a cassette tape of songs similar to the one he wanted. The tape included The Jetsons (1962) theme, selections from Nino Rota's Juliet Of The Spirits, a Remington electric shaver jingle by Frank Zappa, easy-listening music by Juan García Esquivel, and a teach-your-parrot-to-talk record.

Dan Castellaneta designed the character Artie Ziff.

The distinctive voice of "Lunchlady Doris", as well as various other characters, belonged to the show's Script Supervisor Doris Grau. She provided the voice until her death in December 1995.

The map of Springfield, located in the police station, shows the city is shaped almost exactly like medieval Constantinople, complete with a large road in almost the same position as the Mese, the main road of Constantinople.

Places where the "El Barto" graffiti shows up: police station; elementary school; by the lake, where the Indians once lived, and the Kwik-E-Mart in season fourteen, episode nine, "The Strong Arms of the Ma".

Before he opened The Leftorium in the third season, Ned Flanders described his occupation as "the pharmaceutical game".

With the exception of special episodes (such as holidays), the variant ending couch gag, and edited versions, the show kept the same opening sequence for twenty years. It wasn't until February 2009 it received a brand new introduction in conjunction with its switch to high definition. Even then, the new sequence was modelled after the original.

Many of the people and places on this show are named after cities, streets, and landmarks in Oregon, specifically Portland. Springfield is a medium sized city in Lane County, which is home to monuments and museum exhibits of the characters, and has a restaurant called Moe's Tavern (named after the animated one) near its downtown. Many character names (Flanders, Lovejoy, Terwilliger, et cetera) are streets in Portland. Matt Groening grew up in Portland. Eugene, the third largest city in Oregon (and one of the state's great centers of education and performing arts), was founded by a man named Eugene Skinner, and thus has several landmarks with Skinner in the name. Eugene and Springfield are adjacent to each other, and at one point, the border between the two cities is so vague that visitors to the region are sometimes unaware as to whether they are in Eugene or Springfield. Burns is a city in central Oregon.

The animation in the series became noticeably more sophisticated and fluid after the first season. What also changed after the early episodes was Homer's voice (which was made higher pitched and less intelligent-sounding than it initially was), Chief Wiggum's hair color, and Smithers' skin color (he is black in his first appearance, but became yellow/caucasian in all future appearances). Early episodes have a slightly different opening credit sequence. After Homer tosses the radioactive rod into the street, Bart is seen skateboarding, but we do not see any recognizable characters in the streetscape as we do later. The skateboard sequence ends by showing a group of generic townspeople running after a bus. We then see Lisa riding home on her bike, overloaded with schoolbooks, parking it in the garage just before Homer's car pulls into the driveway (after which the credits continue as usual).

Matt Groening is left-handed, and as a result many of the characters on the show are left-handed (though this is not always consistent).The only exception is in season six, episode fourteen, "Bart's Comet", when Skinner and Bart find the comet. Bart uses his right hand in one scene when star watching.

Most of the main cast of Cheers (1982) has appeared on this show. Most notably, Kelsey Grammer as Sideshow Bob. In an episode where Homer was kicked out of Moe's Tavern, he seeks a new bar, and walks into Cheers. This is where the other Cheers (1982) cast members voice their old characters. However, Kelsey Grammer's character of Frasier does not speak.

Season fourteen, episode eleven, "Barting Over" was billed by FOX as the series' three hundredth episode because it was considered to be the three hundredth episode produced. However, FOX does not count the Christmas Special pilot towards that total. So technically, it was actually the three hundred first. FOX was very adamant about airing the three hundredth episode on the same day as the Daytona 500, which is one of the biggest ratings draws of the year for the network, so they pushed the air date back to February 16. So when the episode finally did air, it was the three hundred second to do so (Christmas special included), even though FOX was hyping it up as number three hundred. To further add to the confusion, all previous milestone episodes (one hundredth, one hundred fiftieth, two hundredth, two hundred fiftieth) were based on airing order rather than production order, and with the Christmas special included.

Bart Simpson was ranked number one in TV Guide's list of "TV's 10 Biggest Brats" (March 27, 2005 issue).

The character of Hans Moleman appeared a few times in various background scenes before making his first speaking appearance in season two, episode fourteen, "Principal Charming". At this point, his name, as shown on a driver's license, was "Ralph Melish" (a variation of the Ralph Melhuish character from Monty Python's Flying Circus (1969)). His appearance provoked quite a stir among the writers, because he was written as a generalized "old man" part, but he came back from the animators, in the words of Creator Matt Groening, "looking like a shrivelled potato." They then ended up jokingly referring to him as Moleman, and eventually giving him the permanent name of Hans Moleman.

This is the longest running primetime show in television history, beating Gunsmoke (1955).

Homer's trademark expression is the frustrated "D'oh!" When Matt Groening asked Dan Castellaneta to create an "annoyed grunt" for Homer, the only thing Dan could think of was "D'ooohh...", from James Finlayson of the Stan Laurel and Oliver Hardy films; Finlayson may have created that as a euphemism for the then-forbidden "damn". But Groening thought Finlayson's term took too long to say for the episode time budget, so Castellaneta shortened it drastically. Homer's annoyed grunt (Do'h!) has grown popular since the catchphrase's appearance. After a few seasons, "D'oh!" became firmly set in the American popular lexicon, and the term was accepted for the online version of The Oxford Dictionary. The French version of the television show translated "D'oh" into "T'oh." The Spanish version of the television show translated "D'oh" into "Ouch!" In one episode, Maggie is seen playing with a modelling compound similar to Play-Doh. The label of the compound's container reads "Play- (Annoyed Grunt)". Homer's famous catchphrase "D'oh" is written as "annoyed grunt" in scripts, meaning Maggie's modelling compound is in fact Play-D'oh. Homer's annoyed grunt, "D'oh!", has been added to the Oxford English Dictionary, considered to be the ultimate authority on the English language. In the scripts, Homer's "D'oh" is written as "(ANNOYED GRUNT)", Marge's disapproving murmur is written as "(FRUSTRATED MURMUR)", and Professor Frink's mumblings are written as "(FRINK NOISE)".

Season two, episode three, "Treehouse of Horror", is the only "Treehouse of Horror" to use the treehouse motif, and is so far one of two "Treehouse of Horrors" that don't use the spooky names. The second is season fourteen, episode one, "Treehouse of Horror XIII".

In the DVD commentary for season four, it is said that Bumblebee Man is based on a character in a Mexican sitcom that played a lot in southern California involving otherwise normal-looking people, and someone dressed as a "red cricket". The speakers in the commentary do not provide more information, but this is almost certainly a reference to El Chapulin Colorado, a character played by Roberto Gómez Bolaños "Chespirito", and that appeared in his own show and in sketches from other shows.

Sideshow Bob's real/full name is Robert Underdunk Terwilliger.

The running joke of Bart's prank calls, is he calls Moe's Tavern and asks for whomever he wishes to speak, unbeknownst to Moe, the name is a pun, or double entendre, and says the last name first (I.P. Freely, Ivana Tinkle, et cetera). When Moe realizes the call is a prank, he threatens to reveal his true identity and finds multiple ways to track him down. However, this backfires in season three, episode ten, "Flaming Moe's", when he calls and wishes to speak to a Hugh Jass which is a play on the word "huge ass". Moe initially thinks the call is a prank at first, however, there is actually a person in the bar named Hugh Jass. It backfires again when Bart prank calls Sweden, when someone thanks Bart for providing validation of his World-Weary Cynicism.

Season one, episode thirteen, "Some Enchanted Evening", was originally going to be the season premiere. However, at the Gracie Films studio screening, James L. Brooks said of the animation "this is sh*t", which cleared the room and created a heated argument with Klasky-Csupo animation studio head Gabor Csupo, who countered with "maybe this sh*t isn't funny". An estimated seventy percent of the episode had to be redone, which had several knock-on effects: There was major concern the show would be cancelled if the next episode, season one, episode two, "Bart the Genius", came back in a similar state (luckily it did not). Season one, episode one, "Simpsons Roasting on an Open Fire", was now to be the season premiere, which in turn meant the show could not debut on FOX until December, and what's more, the reordering of the air dates meant that Santa's Little Helper, who now debuted as the "first" episode was mysteriously absent throughout most of the remainder of the season, including this episode. There is also a noticeable difference between the old and new animation, perhaps most notably the scene where Marge is getting ready in front of the bedroom mirror talking to Lisa about Homer's dancing; Marge is hugely off-model and would be unrecognizable under normal circumstances. The delay had at least one positive effect, however; it allowed time for Hank Azaria to overdub the original voice track for Moe (performed by Christopher Collins), and by season two, Azaria had become a regular member of the cast. Sever years later, when Brooks and Csupo were both on-stage accepting an Emmy for "The Simpsons", Brooks jokingly whispered in his ear "maybe this sh*t isn't funny". The joke was taken in good humor as Csupo had long since admitted he was wrong about the whole affair.

The French-Canadian version (different from the France-dubbed version) has many particularities: it is the longest television series dubbed in Quebec, for continuity, which is quite rare, as the producers are very impressed by its quality. Most of the voice actors and actresses are still there (Marge's voice is done by veteran Beatrice Picard, who starred in Quebec-made sitcoms in the 1960s through the 1980s). At one point, some actors died (among them, Benoit Marleau and Jean-Louis Millette, who made voice-dubbing in most television series and movies) and were appropriately replaced. Veteran Hubert Gagnon (Homer's French-Canadian voice) did replace one actor who did Homer's Father Abraham voice (as opposed to Dan Castellaneta, who did both for the entire series). Though many fans asked the producers to re-do a season one DVD, with the French-Canadian version, only the France dubbed version exists up to this day, for the North American DVD.

There was a segment of this show as well which featured Homer rushing around between Tower 1 and Tower 2, trying to locate a bathroom while hoping that the police wouldn't tow away his car, but after 9/11, this segment was removed until its DVD release, out of sympathy for victims of the attacks in real-life.
