What is a punchline?

A punchline is the last part of a joke that delivers the biggest laugh, often following a setup. It is designed to make the audience laugh by providing an unexpected twist or new angle on the topic being discussed. In order to create an effective punchline, it's suggested to brainstorm different humorous endings and test which ones resonate best when performed aloud. Additionally, a punchline can be defined as a critical part of a joke's structure, which typically goes along with a setup and can be characterized by its unexpectedness or cleverness^[2][1][3].
