Trivia: When Kramer is in the soup shop talking to the Soup Nazi there is a black board on the wall that has all the soups on it. If you look closely Mulligatawny (Kramer's soup), Crab Bisque (Jerry's soup), Turkey Chili (George's soup), and Jambalaya (Newman's soup) are all in order.
Trivia: When Jerry, Elaine, and Susan are at the movie "Chunnel", Susan is annoyed while Jerry and Elaine are talking during the movie. Listen to the movie dialogue in the background of the scene. The voice which yells "Everyone out of the chunnel!" is that of co-creator Larry David.

Trivia: One of the subplots concerned Elaine's new boyfriend, "Joel Rifkin". Within the episode, Elaine wanted her boyfriend to change his name because he shared the same name as the serial killer named Joel Rifkin who had been arrested June '93. She has a conversation with her boyfriend, Joel, and suggests he change his name to the less scary Dion, Ned, Remy and then O.J. The show aired in November, 1993, seven months before football Hall of Famer O.J. Simpson would be tried for the murders of Nicole Brown Simpson and Ron Goldman.
Trivia: The blue jumper in the episode that Jerry wears, and that Kramer also ends up wearing that made people sniff appears in a later Seinfeld episode where George is dating the daughter of a welfare officer. She can be seen wearing it when they are sitting in George's car at one point.
Trivia: When Kramer is hosting the show and starts getting a little nervous about Jerry's "questionable material" he tells Newman to put on a tape and it starts playing some music while he talks to Jerry. The music that he puts on is the same music they used in the episode "The Pilot (2)" for the "Jerry" pilot.
Trivia: In the Seinfeld Finale, Jerry and George have a conversation in the jail cell about the positioning of a button on George's shirt. For those viewers who don't know or don't remember, that is why George asks, 'Haven't we had this conversation before?', because this is the same conversation that started off the series in the very first episode.
Trivia: The idea of George returning to work and pretending he didn't really quit was based on a real-life incident. Before co-creating "Seinfeld", Larry David once yelled at a "Saturday Night Live" producer and stormed off the set (he was a sketch writer), only to return the following Monday and act as if it never happened. He actually got away with it.
Trivia: In the scene where Elaine is doing the I.Q. test for George, Babu hands Kramer a face towel, and in his reaction to the towel being too hot, he falls over the chairs and tables. This was totally improvised and the reaction of both Elaine and Babu is one of surprise.
