A one to five minute mini-act at the end of a show, after the dramatic climax of the episode but before (or even during) the end credits, used to show the effects or aftermath of the episode. It might be a humorous
Oh Cisco ending (think
Friends or
Frasier), or move a little bit of
Story Arc plot along in a self-contained episode (think
Farscape). The British spy-series
The Avengers usually ended with a humorous one, often completely unrelated to the main plot.
