Seinfeld ran on NBC from 1989 to 1998, and its distinctive slap-bass theme, composed by Jonathan Wolff, became one of the most recognisable sounds in television comedy. Short variations of that bassline were used throughout episodes to bridge scenes, and editors later lifted those few-second transitions for online videos. On TikTok and YouTube the riff spread as a shorthand for an awkward pause, a failed joke or a sudden change of subject, which is why it still works in short-form comedy long after the show ended.
