A penguin is driving through the desert when his car breaks down. He gets his car towed and the mechanic says it is going to take him about an hour to get the car fixed so the penguin goes next door to get some ice cream.  Penguins love ice cream.

The penguin orders a double scoop of vanilla in a bowl. It is delicious ice cream but the penguin makes a terrible mess trying to eat it.  (Penguins don’t have thumbs. They can’t use spoons.)  Then the penguin goes back to the mechanic to see what is going on with his car.
“Well,” says the mechanic, “It looks like you blew a seal.”
“Nah,” says the penguin, “It’s just ice cream.”
