One day Little David was sitting on a swing munching one candy bar after another. After the 8th one a man sitting on a bench close to him said, "Son, you know eating all that candy isn’t good for you. It will give you acne, rot your teeth and make you fat!"
Little David replied, "My Grandfather lived to be 107 years old!"
The man asked, "Did your Grandfather eat 8 candy bars at a time!"
Little David answered, "No, he minded his own fucking business!"
