A hillbilly kid walks into a Nashville whorehouse and says, "I want a woman, but I've always been scared, because my momma told me a woman has teeth between her legs."
The whore says, "Don't be silly. I'll take care of you."
She brings him up to a room, gets undressed, lies on the bed, and spreads her legs.
She says, "See? There's no teeth between my legs."
The kid says, "You couldn't have teeth down there. Look at the shape your gums are in."."
