How to tell a knock-knock joke like a pro

The secret is the pause. Say "knock, knock," wait for "who's there," and deliver the punchline like it's the most normal thing in the world. The sillier your face stays, the harder everyone laughs.

And if your audience ever gets tired of "knock, knock" — just switch to riddles for a while.
