Joke : How do you know I have had too much to drink?
A man drinking at the bar for three hours, yells at the bartender for another drink. The bartender walks over and tells the man that he has already had too much to drink. The man looks up from his glass angrily and shouts. "I have been drinking for 36 years and I have no idea when I have had too much ...so how the hell do you know?"
