Punch and Judy is a traditional, popular puppet show featuring Mr. Punch and his wife, Judy. The performance consists of a sequence of short scenes, each depicting an interaction between two characters, most typically Mr Punch and one other character. It is often associated with traditional British seaside culture.

The show is performed by a single puppeteer inside the booth, known since Victorian times as a "Professor" or "Punchman," and assisted sometimes by a "Bottler", who corrals the audience outside the booth, introduces the performance and collects the money ("the bottle"). The Bottler might also play accompanying music or sound effects on a drum or guitar and engage in back chat with the puppets, sometimes repeating the same or the copied lines that may have been difficult for the audience to understand. In Victorian times the drum and pan pipes were the instruments of choice. Today, the audience is also encouraged to participate, calling out to the characters on the stage to warn them of danger, or clue them into what is going on behind their backs. Also nowadays most Professors work solo since the need for a bottler became less important when busking with the show gave way to paid engagements at private parties or public events.

Everyone knows that Punch mishandles the baby, that Punch and Judy quarrel and fight, that a policeman comes for Punch and gets a taste of his stick, that Punch has a gleeful run-in with a variety of other figures and takes his stick to them all, that eventually he faces his final foe (which might be a hangman, the devil, a crocodile, or a ghost).
