Knock-knock joke

The knock-knock joke is a question-and-answer joke, typically ending with a pun. Knock-knock jokes are primarily seen as children's jokes, though there are exceptions.

The scenario is of a person knocking on the front door to a house. The teller of the joke says, "Knock, knock!"; the recipient responds, "Who's there?" The teller gives a name (such as "Noah") or a description (such as "Police") or something that purports to be a name (such as "Needle"). The other person then responds by asking the caller's surname ("Noah who?" "Police who?" "Needle who?"), to which the joke-teller delivers a pun involving the name (" place I can spend the night?" " let me in—it's cold out here!" " help with the groceries!").
