Guy walks into a bar and orders a double. Bartender sets him up and the guy chugs it. "Give me another!" The guy says. Bartender sets it down and it too is gulped down. "One more time!" Drink comes and is gone in a flash. Bartender says" well, you're drinking those awfully fast." Guy says " you'd drink 'em fast too if you had what I have!" Bartender asks" what ya got?" Guy says " 50 cents."
