Running Gag

A recurring joke, line, action, or comedic bit that is revisited multiple times throughout a performance, ideally building in humor with each repetition. Also called a "runner," this device works by establishing a pattern early in a show and then returning to it at unexpected moments, with each callback gaining momentum from the audience's recognition and anticipation. The technique can take many forms: a repeated catchphrase, a physical action, a character trait, or a thematic motif that performers keep coming back to as the show progresses. In sketch and variety formats, running gags often thread across otherwise unrelated scenes, providing continuity and a sense of shared history between performers and audience. The comedy typically escalates through variation rather than pure repetition; each return to the gag adds a new twist, context, or heightened absurdity. Classic examples from radio and television, such as Fibber McGee's closet gag, demonstrate how a well-crafted runner can become a signature element of a show, with audiences eagerly anticipating each recurrence. In longform improvisation, a running gag often emerges organically from an early scene detail that performers collectively recognize as worth revisiting.
