Knock knock. Who's there? Candice.

Candice who? Candice door open? I'm getting board waiting!

Knock knock. Who's there? Hugh.

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? Tank.

Tank who? You're welcome! No, seriously, *tank* you for opening the door; I was starting to lose my *bearing* out here.

Knock knock. Who's there? Alpaca.

Alpaca who? Alpaca the bags, we're going on vacation!
