As autumn approached, two elderly vultures doubted they could make the migration trip south, so they decided to go by airplane. When they checked their baggage, the attendant noticed that they were each carrying two dead raccoons. “Do you wish to check the raccoons through as luggage?” she asked. “No, thanks,” replied the vultures. “We will take the raccoons on board.” “You will have to check two of the raccoons as baggage,” the attendant replied. “You are only permitted one carrion per passenger.”
