A penguin was driving down a long highway when his car just up and died. After poking around under the hood, he decided he better head towards the nearest town and ask for help.
Hours pass as he's walking, when he finally reaches a small podunk town with a garage. He walks up to the mechanic and tells him his trouble. The mechanic gets the keys to his tow truck, and before he leaves, he tells the penguin, "Well, it's gonna be a little while for me to pick up yer car and have a look at it in the shop. While yer waitin', y'can go over to that kwik-mart and have a soda or somethin'."
The penguin agrees, and the mechanic heads out.

Looking around inside the store, the penguin notices an ice-cream freezer and looks in. To his suprise, he sees Eskimo Bars, lots of them. He is taken back to when he was a kid, and remembers how much he liked them. And, since it's been a long time since he's had one of these, he buys quite a few of them and sits down on the curb outside to munch down.
Without remorse, he tears into all of them, just completely gobbling them up, cherishing the flavor and the creaminess, and making a complete mess of himself. He's getting ice cream all over himself; all over his arms, all over his face, his chest, his hands - everywhere.
Within minutes of eating all this, all in the heat from the sun above and the feverish feasting below, he's done. This gave the mechanic enough time to get the car and take a look under the hood. So the penguin daudles over to see what's up.

He walks into the garage and over to the mechanic, who is on a creeper under the car. Bending down, he asks, "Have you found what's wrong?"
The mechanic wheels out from under the car to see the penguin, and says, "Well, I don't know, but it looks like you blew a seal."
The penguin looks at himself and yells "NO! THAT'S ICE CREAM!"
