This one is from SuperBike
Man walks into a bar and asks for a beer.
After drinking it, he looks in his shirt pocket and orders another one.
After drinking that one, he looks in his pocket again and asks for another.
This happens another seven times before the bar tender asks him "Why do you keep looking in your pocket?"
The man replies, "There's a picture of my wife in there. When she looks good enough, I'll go home."
