A passer-by noticed an old lady sitting on her front step: "I couldn't help noticing how happy you looked! What is your secret for such a long, happy life?"
"I smoke 4 packs of cigs a day", she said. "Before I go to bed, I smoke a nice big joint. Apart from that, I drink a whole bottle of Jack Daniels every week, and eat only junk food. On weekends I pop a huge number of pills and do no exercise at all."
"This is absolutely amazing at your age!!!!", says the passer-by, "How
old are you?"
