A penguin is driving through the desert in his nice air conditioned car. All of a sudden, he notices that the AC is not working so he stops at the first repair shop he finds. The mechanic tells the penguin to go into the ice cream shop to stay cool while he looks at the penguin's car.
After an hour or so of eating ice cream and staying cool, the mechanic shows up to tell the penguin the diagnosis.
The mechanic walks in to tell the penguin what is wrong with his AC and sees the penguin in the corner of the shop with ice cream all over his face.
The mechanic says to the penguin, "well, it looks like you blew a seal."
The penguin says "no, it's just ice cream."
