I present to you photographic evidence that eating too many Kit Kats does indeed cause bodily harm:

THAT is Kit Kat Belly. It's a condition that is likely to result in your shirt riding up and your jeans coming unsnapped. Repeatedly.

Hitting the dog on the head with a maraca will not cure your Kit Kat Belly. It will, however, get you in big trouble with your Mother and she WILL make you feel bad for being mean.
