I have said it before and I'll say it again. I know a good idea when I steal one. I "stole" this one from Carmon at Buried Treasure. It is HILARIOUS! I promise you will laugh or your money back.
My kids were rolling around the floor cackling at the line, "I'm gonna tear up your behind." I really have NO idea why because we certainly do NOT use language like that in this household.
We say hind end.
