who's there

After the knock

Who's there is the standard response to a knock at the door, asking the visitor to identify themselves: Who's there? It's me, open up.

The phrase also serves as the setup for knock-knock jokes, where the asker says "Knock knock," the responder says "Who's there?" and a pun follows.

In drama, it opens Shakespeare's Hamlet, spoken by a guard in darkness.
