A penguin was driving down the road one night, when the "Check Engine" light came on. He pulled over at the gas station, and the attendant said he'd take a look at it, and tell him what was wrong.
The penguin went over to a nearby shop and bought a vanilla ice cream cone. He finished the ice cream, threw the wrapper away, and walked back to the gas station, where the attendant was waiting for him.
"It looks like you blew a seal," said the attendant.
"Oh, no. Its just vanilla ice cream," replied the penguin.
