Seinfeld ran on NBC from 1989 to 1998, and its scene transitions became almost as famous as the jokes themselves. Composer Jonathan Wolff wrote the now-iconic slap bass riffs, recording dozens of variations so no two scene changes sounded exactly alike. Clips of the transitions spread through video edits and memes in the 2010s, where creators used the riff as shorthand for a comedic cut or awkward beat. It remains one of television's most parodied musical signatures, up there with the DUN DUN sting from Law & Order.
