Once a man walked into a bar and sat down at a booth.
Eventually, he and another man got into an argument about whose dog could whoop the other dog.
The man said, "Let's have a fight out back.''
''Okay'' said the other.
When they got their dogs, one man opened a case and brought out a 12 inch long yellow dog.
That dog proceeded to kill every other dog in town.
When one man asked, ''Where did you get that dog?'' the man said, ''Well, before I cut its tail off and painted it yellow, it was an alligator."
