The drum hit joke sting comes from the traditional rimshot used by live drummers in vaudeville and stand up comedy clubs to mark the end of a joke. As recorded sound effects replaced live bands, the short snare and cymbal hit became a stock audio cue in radio, television and cartoons. Online, creators adopted it as a quick shorthand for a punchline, keeping the same timing editors have used for decades in sitcoms, variety shows and short meme videos.
