Answer: In the episode where Kramer goes to baseball fantasy camp, George says Kramer's life is a fantasy camp and that he "fell ass-backwards into money." It's never explained where this money comes from or what Kramer did to get it, but that's how he's able to afford the lifestyle he leads. Although the episode where Jerry buys his dad a Cadillac, Kramer sees the check Jerry earned for his comedy gig and didn't realise Jerry made so much money that he felt uncomfortable about knowing the amount, so it's not like Kramer is sitting on a ton of money, which is why he does all his schemes and side jobs.

Answer: This is gleaned from the Internet, though it seems a bit far-fetched that it would provide enough for all his living expenses: Kramer has a variety of ways of making a living, including gambling, working in various theater projects, acting out illnesses at a medical school, getting a spot on the show "Murphy Brown", and pitching ideas for inventions like his "Coffee Table Book."

Answer: It was never revealed as part of the gag. Jerry admits to Kramer it was over $300 and seems to suggest it was over $400. But then Jerry stays silent when George starts to question him about the price and George leaves thinking The Jacket cost over $1,000. Whether or not Jerry remained silent to tease George or because he did in fact pay over $1,000 is also unknown.

Answer: It was sort of an urban legend that started when people noticed Jerry has a Superman figurine on his bookshelf. Barry Freiman, a writer who has written about Superman and pop culture, says he watched every Seinfeld episode looking for a reference in each one and said even though there's a lot, it not in every episode. When Jerry Seinfeld was asked about it, he said you can't count seeing the Superman model as a reference to Superman and there's maybe 10 episodes that actually reference Superman.

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".
