6. Jerry and George have the same conversation twice. The first conversation Jerry and George have at the coffee shop is about a shirt button. This also happens to be the last conversation they have with George commenting on a button while in his cell. Jerry acknowledges the callback, saying how it feels like they’ve had the conversation before.
7. Kramer went from Hoffman to Kessler then back to Kramer. In the first draft of the script, Kramer’s name was changed to Hoffman. NBC felt that using Kramer could cause some legal issues since the character was based on Larry David’s real-life next door neighbor, Kenny Kramer. Hoffman was changed to Kessler before filming, but only spoken once by Jerry while watching the Mets game. By episode two, Kessler was swapped for Kramer and Kenny Kramer was free to start planning his reality tour.
8. The show had four different titles. The pilot episode might have run under the title The Seinfeld Chronicles, but that wasn’t even the first title for the show. The script that was delivered to NBC was titled Stand Up — to go along with the heavy amount of stand-up footage that would be in each episode. Before the script landed in the hands of NBC, Jerry Seinfeld and Larry David were just calling it the generic sounding The Jerry Seinfeld Show.
9. Julia Louis-Dreyfus’ husband auditioned for the part of George. Jason Alexander auditioned twice for the part of George — the first time in New York and a second time in Los Angeles. Before he landed the part, he was up against actors Nathan Lane, David Alan Grier, Steve Buscemi, and Julia Louis-Dreyfus’ husband, Brad Hall.
10. The rerun of the episode helped secure the show’s second season. NBC executives were on the fence about the show, fearing that it was just “too New York and too Jewish.” NBC’s head of late night programming, Rick Ludwin was able to convince the network to produce four more episodes. None of them did especially well, but when NBC reran the pilot in 1990 it received a Nielsen rating of 13.9, better than its original score of 10.9. This helped convince the Network to produce another season.
