An obnoxious drunk stumbles into the front door of a bar and orders a drink, the bartender says, 'No way buddy you're too drunk.'

A few minutes later the drunk comes in throught the bathrooms, again he slurs 'give me a drink', bartender says 'No man I told you last time you're too drunk'

Five minutes later the guy comes in through the back door and orders a drink, again the bartender says 'You're too drunk'

The drunk scratches his head and says 'Damn I must be... the last two places said the same thing.'
