A penguin takes his car to the mechanic because it has a bad oil leak. When he gets there the mechanic tells him that he is very busy so could he leave the car there for an hour or so and he'll have a look at it for him.
The penguin goes for a walk down to the beach, has a look around the shops and gets a extra large vanilla ice cream cone. He heads back to the mechanics and finishes the icecream just as he gets there. Trouble is it's a hot day and a lot of it has melted and is all over his chin and down the front of his shirt. The mechanic comes out and says " Looks like you blew a seal." and the penguin, wiping his chin, says" nah, I just had an icecream.
