Little Billy was sitting on a park bench, busily munching candy bars one after another.
After he had eaten the sixth candy bar, a man who had been observing him from the bench across from him said, “Son, you know that eating all that candy isn’t good for you. It will give you acne, rot your teeth, and make you fat.”
Little Billy replied, “My grandfather lived to be 107 years old.”
“Oh?” replied the man, rather taken aback. ” Did your grandfather eat six candy bars at a time?”
“No” replied Little Billy, “he minded his own business!!”
