A man walks into a bar, sits down on a bench, and orders a cold one. He swigs down the beer, looks in his pocket, cringes and orders another.  He gulps down that one, looks in his pocket again, cringes again, and orders yet another one.  This goes on for at least an hour and a half.  Finally the bartender, bursting with curiosity, says, "I know its none of my business, but I have to ask.  Why the whole "drink, look in pocket, cringe, and order another one" routine?"  "Well," slurred the man,"There's a picture of my wife in my pocket.  When she stars to look good, then it's time for me to go home."
