About this tool
The knock-knock joke generator reveals each joke one line at a time, so you and a friend can do the classic call-and-response: ‘Knock knock!’ — ‘Who’s there?’ The pacing makes the punchline land, instead of dumping the whole joke at once.
Every joke in the deck is clean and family-friendly, making this great for kids, classrooms, road trips and party warm-ups. Jokes are chosen at random, so the next groan is always a surprise.
