An Alcoholic, a Chain Smoker and a Homosexual go to the doctor. 14 5
The doctor says: "If any of you indulge one more time you'll die."
As they walk home they pass a bar. The Alcoholic has a shot of whiskey, falls off his stool stone cold dead. His friends are shocked.
As they walk along they come upon a cigarette butt lying on the ground still burning. The Homosexual looks at the Chain Smoker and says: "If you bend over to pick that up, we're both dead!"
