Rumplepeniskin 

A German folktale told in the early 1900s, this is believed to have validated circumcisions outside of the Jewish Faith. The tale told of an old man who's foreskin hung to the ground and became a toy for neighborhood dogs. It was told as a bedtime story to make sure children cleaned under their foreskin after a Fasturbating match at school.

"Son, did you win your Fasturbating match in gym today?"
"No, I lost because my foreskin was rumpled."
"Well just make sure you don't forget the tale of Rumplepeniskin!"
