A man walks into a bar and asks for a Guinness.
After drinking it, he looks in his shirt pocket and asks for
another Guinness.
After drinking that one, he looks in his shirt pocket again and
asks for another Guinness.
This happens about another seven times before the bartender asks
him, "Why do you keep looking in your pocket?"
The man replies, "I have a picture of my wife in there. When she
looks good enough, I'll go home."
