A penguin was driving his car to work one day and noticed that the car wasn't running as smoothly as it used to be so he took it to the mechanic. The mechanic told him that it would take him about an our to find the problem so the penguin goes and gets an ice-cream cone. The penguin comes back and the mechanic says, "Looks like you blew a seal." "No," replied the penguin, "that's just the ice-cream."
