Trivia: Newman's appearance in the episode is an obvious reference to Harvey Keitel's character The Wolf in "Pulp Fiction". Before Newman arrives, Elaine mentions that he "makes problems go away" just like The Wolf. Newman even uses the same "If I'm curt" line.
Trivia: Despite Christine Taylor (the woman Jerry is dating in the episode) now being the real-life daughter-in-law of Jerry Stiller (who plays George Costanza's dad), Taylor didn't meet Jerry's son, Ben Stiller, until 2 years later.
Answer: Composer Jonathan Wolff used a synthesizer, although in seasons 7-9, a real bass is used in addition. Wolff also recorded himself making hundreds of mouth noises, pops, and slaps to add to the synthesized bass licks so that each episode has a different theme. The only real "back-story" is Jerry Seinfeld was having trouble coming up with a theme song and talked to a friend who happened to know Wolff. They wanted to avoid that cheesy late 80's sit-com theme song and Wolff came up with what we enjoy now. Jonathan Wolff has also talked about this further in interviews, recently Reed Dunela interviewed him, so for a fuller account of his story; check out "The Wolff of 116th street".
