The best porno either, infamous for a woman with four penises in her at the same time. Then stands over the men and pees on them, Five midgets. Spanking a man. Covered in thousand island dressing.

First gained popularity in South Park.
Randy: "Yes... uh... you see Token, that was called a pornographic film. Uh, it shows adult men and adult women having sexual intercourse." Token does not respond, but instead continues to stare blankly "You see when a- when a man and woman are in love, the man puts his penis into a woman's vagina. It's called love making, and its part of being in love." There is a long pause before Token at last speaks
Token: And when a woman has four penises in her at the same time. Then stands over the men and pees on them, is that part of being in love too? Five midgets. Spanking a man. Covered in thousand island dressing. Is that making love?"
Mr. Black: "Jesus! What kind of porno was that?!"
Gerald: "Back-Door Sluts 9"
Mr. Black: "Oh Jesus! Not that one!"
