The bass interludes were composed for Seinfeld, the NBC sitcom that ran from 1989 to 1998 starring Jerry Seinfeld as a fictionalised version of himself. Composer Jonathan Wolff created the slap bass style to match Jerry's stand-up segments and to give each episode a flexible transition that could be timed to jokes. Online, the riff escaped the show through reruns, clips and edits, becoming shorthand for a smug sitcom cutaway, much like the Law and Order DUN DUN works for drama. Its brevity keeps it endlessly reusable.
