A man walks into a bar one evening. He sits down at the bar and asks for a double shot of whiskey. He sits there for a while and drinks it and then asks for another. After four shots of whiskey he looks into his pocket, shakes his head and asks the bartender to give him another. This goes on for about four hours. Finally the bartender asks him what's going on. He asks, "Every evening you come in here and drink whiskey and look in your pocket. What's going on?" The man replies, "I drink a little and then I look in my pocket at a picture of my wife. When she looks good, I go home."
