Little Johnny was sitting at a table by himself during lunch and pulled out eight Snickers bars. After he ate the first seven, he was just getting to the unwrapping of the eighth one when an old lunch lady walked by and saw all the wrappers.

"You know that those candy bars will rot your teeth, give you acne and make you fat. You shouldn't eat that many at once," the old lady said.

"Well, my great-grandfather lived to be 107 years old," Little Johnny said.

"Did your grandfather eat eight Snickers bars at one time?" asked the old lady.

"No," said Johnny with a smirk, "He minded his own fucking business."
