"Slowly He Turns, Inch by Inch" joke

The owner of a bar is just locking up for the night when there is a knock at the door.

He opens the door and there's a snail sitting on the doorstep.

"What do you want?" asks the owner.

"I want a beer," says the snail.

"First of all, we're closed, and second of all, we don't serve snails. So go away!"

The snail begs and pleads for a beer.

The owner finally gets fed up, kicks the snail, and slams the door.

"What'd you do that for?" asks the snail.
