The slap-bass transitions were composed by Jonathan Wolff for Seinfeld, which aired on NBC from 1989 to 1998. Instead of a fixed theme, Wolff recorded improvised funk bass interludes to cover scene changes, giving the show its distinctive bouncy sound. Clips of these transition stings became shorthand online for awkward comedy and retro sitcom humor, widely reused in memes, edits and reaction videos. Their short length and instant recognizability keep them popular as punchline cues decades later.
