Penguin is driving his car on a very hot day when he notices steam coming from under his hood. He pulls into the first gas station he spots and asks the mechanic to take a look. Mechanic tells the penguin he'll need about a half-hour to diagnose the problem. The penguin spots a Ben & Jerry's ice cream store down the block. Hot and tired, the penguin waddles off to get a big ice cream cone.
After a while, he waddles back to the gas station, licking his cone, to inquire about the problem with his car. "Looks like you blew a seal," the mechanic says. "Naw," replies the penguin, "it's just the damn ice cream melting."
