Dog walks into a bar and orders a drink. Bartender says, "We don't serve dogs here," pulls a pistol and bam! shoots the dog in a hind foot. The dog hops howling out of the bar holding his foot.
Next day, dog walks back into the bar, dressed in a cowboy outfit, ten-gallon hat, a six-gun on each hip.
Everyone looks at him and falls silent.
Dog looks around at everyone and says,
"I'm lookin' for the man who shot my paw."
