The interstitial bass riffs were created by composer Jonathan Wolff for Seinfeld, which aired on NBC from 1989 to 1998. Wolff improvised the funky electric bass licks to cover scene changes, tailoring each one to the episode's timing instead of using a fixed theme. Clips of the transitions became a shorthand for nineties sitcom comedy on YouTube and TikTok, where editors reuse them to signal ironic scene changes. The sound endures because it instantly frames any mundane moment as a self-aware sitcom beat.
