Callback (comedy) in the context of "Catchphrase"

A catchphrase (alternatively spelled catch phrase) is a phrase or expression recognized by its repeated utterance. Such phrases often originate in popular culture and in the arts, and typically spread through word of mouth and a variety of mass media (such as films, internet, literature and publishing, television, and radio). Some become the de facto or literal "trademark" or "signature" of the person or character with whom they originated, and can be instrumental in the typecasting of a particular actor. Catchphrases are often humorous, can be (or become) the punch line of a joke, or a callback reminder of a previous joke.
