Seal at the mechanic
A penguin takes his car to the shop to have it fixed. While he's waiting, he goes into a cool ice cream shop and eats ice cream. Having flippers instead hands, he gets the ice cream all over himself. He's goes back to the auto shop and asks the mechanic what was wrong with his car.
"Well," says the mechanic, "it looks like you blew a seal."
The penguin replies, "It's just ice cream, I swear!!"
