A man is walking a tailess little yellow dog on a leash when another man walking a snarling pit bull comes up. The pit takes a run at the at the little yellow dog, growling and snapping. The little dog opens enormous jaws and bites the pit bull in half.
The pit bulls owner stares and says ''Lord man, what kind of dog is that?''
"Well, before I cut off his tail and painted him yellow, he was an alligator.''
