Little Johnny was sitting on a park bench munching on one candy
 bar after another. After the 6th one a man on the bench across
 from him said, "Son, you know eating all that candy isn't good
 for you. It will give you acne, rot your teeth, make you fat."
 
 Little Johnny replied, "My grandfather lived to be 107 years old."
 
 The man asked, "Did your grandfather eat 6 candy bars at a time?"
 
 Little Johnny answered, "Naw, he minded his own damn business."
