The Fatigues - S8-E6
Continuity mistake: At the start of the episode, Cynthia is drinking a glass of wine. While speaking near the end of the scene, she is holding the glass in her right hand and says, "You know, guides you in your career path." The next shot is of Jerry and instantly the glass has disappeared from her hand with her right hand resting on the table. You can also see the glass is closer to her left hand now.
The Fatigues - S8-E6
Continuity mistake: When Frank breaks open an egg in the close-up of the pan, we see there are more than half a dozen eggs in the carton. However, in a wideshot of the kitchen, the carton appears to have only about three eggs. (00:16:15)
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".
