A lesson that some people will never learn.

Little Johnny was on a park bench stuffing all of his Halloween candy in his mouth. An old lady came over and said. "Son, don't you know that eating all of that candy will rot your teeth, give you acne, and make you sick?"

"My grandfather lived to be 105 years old!" replied Johnny.

"Did he eat five candy bars at a sitting?" the old lady retorted.

"No," said Johnny, "but he minded his own freakin' business."
