A dog walks into a bar in the Old West and orders a beer.
The bartender says, "We don't serve dogs here," pulls a pistol and shoots the dog in a hind foot. The dog hops yelping out of the bar holding his foot.
The next day the dog walks into the bar wearing a cowboy hat and a six-gun on each hip. His foot is bandaged. Everyone looks at him and the bar falls silent.
The dog looks slowly around the bar and says,
"I'm looking for the man who shot my paw."
