Seinfeld ran on NBC from 1989 to 1998, and every episode was stitched together with short slap-bass stings composed by Jonathan Wolff, who played the popping bass lines on a keyboard sampler. The riffs were written to match each scene change, so no two are exactly alike, yet all share the same cheeky funk feel. Online, the sting became shorthand for a comic scene change, used the same way as the Law and Order DUN DUN marks a dramatic reveal. Fans drop it into edits whenever a cut needs that unmistakable nineties sitcom flavor.
