A traveling salesman stops at a ramshackle rundown farmhouse. He knocks on the door and an ugly, ugly little boy answers the door. The salesman is taken aback and asks, "Uh, is your mother or father at home?"
The little boy casually answers, "I ain't got no daddy, and Mama's out back havin' sex with a goat."
The salesman exclaims, "Doesn't that bother you!?"
The little boy bleats, "Nah-a-a-a-a-a-a-a"
