How to Tell a Knock Knock Joke
The setup is simple but timing matters. Here’s how to nail it:
Start with confidence. Say “Knock knock” like you mean it. No hesitation.
Wait for them to respond. If they don’t say “Who’s there?” just stare at them until they do.
Pause before the punchline. Let them anticipate it. The groan is sweeter when they see it coming.
Keep a straight face. The sillier the joke, the more serious you should look.
