A penguin is driving through the desert and his car breaks down. He calls AAA. His car is towed to the nearest garage and the mechanic says he'll need a couple of hours to check out the car.
The penguin doesn't complain, but wanders off to find the closest supermarket. He goes to the frozen foods section, gets into the freezer and eats a few gallons of vanilla ice cream to kill some time.
Later, covered with ice cream, he goes back to see the mechanic. The mechanic, wiping his hands, walks over to the penguin, shaking his head saying, "It looks like you blew a seal." Blushing, the penguin said, "Oh, no, really--it's just ice cream."
