"One Too Many" joke
A man, obviously quite drunk, enters the front door of a bar, staggers up to a stool, sits down and, with a belch, orders a drink. The bartender politely informs the man that it appears he's already had one too many, he would not be served additional liquor at this bar, and could he call a cab for him?
Surprised, the drunk softy scoffs, grumbles, climbs down from the bar stool and staggers out the front door.
A few minutes later, the same drunk stumbles in the SIDE door of the bar, wobbles up to the bar and yells for a drink. The bartender approaches him and, still politely - but more firmly, refuses to serve the man due to his inebriation, and again offers to call a cab. The drunk glares at the bartender, curses, and shows himself out the side door, all the while grumbling and shaking his head.
A couple of minutes later, the same drunk bursts in through the BACK door of the bar, climbs up on a stool, gathers his wits and belligerently orders a drink. The bartender comes over and emphatically reminds the man that he is obviously very drunk, he will not be served any drinks, and either a cab or the police will be called immediately.
The surprised drunk looks at the bartender, and in hopeless anguish, cries, "OHHH, MAAAN! How many bars do you work at?"
