The preservation of ad libs, improvisations, and the occasional accident or mistimed what-have-you for dramatic or comic effect, sometimes at the cost of continuity.

These are often some of the most memorable scenes, for better or for worse, due to their spontaneity.

Differs slightly from attaching HilariousOuttakes to the ends of shows. Related to NoFourthWall and EnforcedMethodActing - especially in cases of pain and surprise. See also RuleOfFunny, RuleOfCool.

Not to be confused with EnforcedMethodActing, when something unexpected is deliberately done ''to'' an actor in order to elicit a realistic response, or {{Improv}}, where there is very little or no script at all and the actors are making up large chunks as they go along.
