If you don't want to laugh, then don't watch this show. There is no better show than Seinfeld and there never will be. When you take those 4 and put them in a room there is no better TV magic. The show never gets old and is still funny after watching the same episodes many many times.
Jerry: The comedian who is like the ringmaster for his three puppet friends (haha) all kidding aside he is the main character. The man who is kind of a clean freak who hardly ever wants to do anything for anyone else, eats cereal and worships Superman all day. Goes through girlfriends one by one (he seems to have a new one every episode). And even after he breaks up with his girlfriends he would usually like to remain friends.
George: Probably the unluckiest bastard in television history. He could never hold down a job until season 6 on. Relationships never came easy to this man, and often said that he could never imagine himself having sex ever again. Often went through mishaps that left him hated by others, or made him hate others. Really doesn't care about the misfortune of others, and often lies in an attempt to get money or to benefit himself and nobody else.
Kramer: Probably the luckiest bastard in television history. This man has had one job that we known about, and always seems to get by. Kramer lives a better life than George by doing nothing but staying at home and mooching off Jerry. Kramer often comes up with harebrained schemes with Newman, or comes up with his own ideas or inventions.
Elaine: Elaine is the nicest of the bunch, but later in life became a witch. Her and Jerry dated but remained friends. She has always worked in publishing and eventually became the President of The J. Peterman Company. She has no other friends who are girls, she is indeed a friend of men, not ladies.
It had 9 seasons but wasn't canceled, NBC was really desperate to get a 10th season but Jerry Seinfeld wanted to go out on top. NBC was willing to pay Jerry 5 million dollars an episode for a 10th season, but he declined, Jerry is in the Guinness Book Of World Records for most money turned down.
