A vacationing penguin is driving through Arizona when he notices
that the oil-pressure light is on. He gets out to look and sees
oil dripping out of the motor. He drives to the nearest town and
stops at the first gas station.
After dropping the car off, the penguin goes for a walk around
town. He sees an ice-cream shop and, being a penguin in Arizona,
decides that something cold would really hit the spot. He gets a
big bowl of vanilla ice cream and sits down to eat. Having no
hands, he makes a real mess trying to eat with his little
flippers.
After finishing his ice cream, he goes back to the gas station
and asks the mechanic if he's found the problem. The mechanic
looks up and says, "It looks like you blew a seal."
"No, no," the penguin replies, "it's just ice cream."
