Seinfeld aired on NBC from 1989 to 1998, created by Jerry Seinfeld and Larry David, with its musical transitions composed by Jonathan Wolff. Wolff built short slap bass riffs to bridge Jerry's stand-up segments and scene changes, varying them across episodes. The style became one of television's most recognisable audio signatures. Online, clips of the riff spread through meme edits and reaction videos, where the sound alone now implies an ironic observational joke is coming, even without any footage from the show itself.
