This dog goes into a bar. The barkeep says "We don't allow dogs."
So the dog lifts his leg on one of the customers.
"I said we don't allow dogs."
He goes back and lifts his leg on the same customer again.
"Get out of here you mangy mutt."
"So, the dog goes over and lifts his leg on the customer for the third time."
"That's it. The barkeep picks up a large axe." The dog runs out the door.
"It's about time" a woman in a short skirt says. "That guy paid me a lot of money to do that just across the street. I can't have the dog doing it for free."
