A joke is a form of humor that typically consists of a setup and a punchline. The setup introduces a situation or premise, while the punchline delivers an unexpected twist or conclusion that elicits laughter. Jokes can take various forms, including one-liners, anecdotes, or riddles, and they often rely on wordplay, absurdity, or cultural references. Jokes are commonly shared in social settings and can serve as a way to bond with others. They are found in many forms of media, including stand-up comedy, television shows, and internet memes. The effectiveness of a joke often depends on timing, delivery, and the audience's sense of humor.
