Seinfeld ran on NBC from 1989 to 1998, created by Jerry Seinfeld and Larry David. Instead of a traditional theme, composer Jonathan Wolff recorded funky slap-bass interludes that were timed to the rhythm of Seinfeld's stand-up bits and used to cover scene changes. Those short riffs became one of the most imitated sitcom transitions on television. Online, creators lifted them to parody nineties comedy pacing, and the bass sting is now shorthand for an ironic cutaway or a deliberately dated punchline in memes and video edits.
