The riff comes from Seinfeld, the NBC sitcom that ran from 1989 to 1998 and starred Jerry Seinfeld as a fictionalised version of himself. Composer Jonathan Wolff created its slap bass theme, using short bass interludes instead of a traditional laugh-track transition to move between scenes in New York. Clips of the riff spread through soundboards, YouTube compilations and TikTok edits, where the sound became shorthand for a sitcom-style scene change. It remains popular because the two-second groove is instantly recognisable, funny without words, and easy to drop into almost any edit.
