A man was walking his big ferocious dog, which had fought
many other dogs in its life, when he met another man
walking a long low yellow dog. The two dogs naturally
began to fight, and the long low yellow dog ate the big
ferocious dog. The first man was aghast:
  "What kind of a dog IS that, that could eat my big dog?"

  "Before I cut its tail off and painted it yellow, it was an alligator"
