A drunk staggers into a bar demanding a beer. The bartender informs him that he is not allowed to serve alcohol to drunken patrons. After a few harsh words, the bartender suggested that the drunk prove he isn't drunk by doing twenty push-ups on the floor.
As he was doing the push-ups, another drunk staggers into the bar and sees this guy on the floor doing push-ups.
He looks at him for a minute and then nudges him in the ribs saying, "Hey, Pal, I think your girl friend has gone home."
