Punchline

A punch line concludes a joke; it is intended to make people laugh. It is the third and final part of the typical joke structure. It follows the introductory framing of the joke and the narrative which sets up the punch line. For example, a certain bar joke has the framing of "A man walks into a bar...", the brief narrative of "he hurts his head", and the punch line of "It was an iron bar!"
