The Drunk

A drunk guy stumbles into the bar and asks for a beer. The bartender says, "No way, you've had enough." So the drunk leaves. The drunk then enters the bar from the rear door and asks the bartender for a drink. The bartender refuses and asks the drunk to leave. The drunk comes back into the bar through the front door and asks for a drink. The bartender says, "Listen, I'm not giving you a damn drink, you're already drunk enough." The drunk says, "DAMN, MAN! How many bars do you work at?"
