A travelling salesman was passing through a small town in the West when he saw a little old man sitting in a rocking chair on the stoop of his house. The little old man looked so contented that the salesman couldn't resist going over and talking to him. "You look as if you don't have a care in the world," the salesman told him. "What is your formula for a long and happy life?" "Well," replied the little old man, "I smoke six packs of cigarettes a day, I drink a quart of bourbon every four hours and six cases of beer a week. I never wash and I go out every night." "My goodness," exclaimed the salesman, "that's just great! How old are you?" "Twenty-five," was the reply.
