A guy walks into a bar and asks for a beer. He chugs it, looks into his pocket and asks for another beer. He chugs that beer, looks into his pocket and asks for another.
The man does this a few more times until the bartender asks, "How come you ask for a beer, chug it, then look in your pocket?"
The man says, "Because there is a picture of my wife in my pocket and I'm gonna keep drinking till she looks good enough for me to go home."
