A man weaving up to a local bar orders a whiskey. The bartender Joe, noticing the condition of Tony, says, "I can't serve you Tony, you have had too much to drink."

Tony walks around the block and comes in the side door and orders a whiskey. Joe again says, "You have had too much already. I can't serve you."

Tony walks the block again and comes in the back door and orders a whiskey and before Joe has a chance to refuse him the drink, Tony says, "Hey Joe! How many places do you work at?"
