The Penguin and the Mechanic
Once there was a penguin whose car broke down. He took it in to get it serviced, and while it was being worked on, he went shopping.
He returned later that day to see what had happened to his car, and the mechanic told him, "It looks like you've blown a seal."
The penguin, chuckling, and wiping his beak replied, "No, I've just eaten some ice-cream."
