The door-to-door salesman knocked at the house. A strange and grubby little boy answers.

The salesman reels at the "unusual" looks of the kid.... and then asks, "Hello sonny, where's your Mommy?"

The kid says, "Oh, she's out back having sex with the billy goat."

The salesman exclaims, "Oh, that's the sickest thing that I've ever heard!"

The kid replies, "On no.... it's not that BAAAAAAAAAAd."
