Hugh who? Hugh-man, I've got a 'Hugh'-ge request: can you 'Hugh'-mor me by letting me in? Because this joke is so pun-tastic, you'll 'Hugh'-rry to tell all your friends, and they'll 'Hugh'-ge-ly regret not being here to 'Hugh'-ear it first!

Knock knock. Who's there? This is a knock-knock joke.

This is a knock-knock joke who? Just trying to figure out where we go from here.

Knock knock. Who's there? Maple.

Maple who? Maple you a favor and open the door!

Knock knock. Who's there? Donut.

Donut who? Donut even think about leaving me out here!
