Originally, there was supposed to be a scene where Shelley sets Stan on fire, then douses him out with water. Comedy Central forced Matt and Trey to cut it out of fear that impressionable viewers will imitate the stunt and the show would be plagued with the same controversy over dangerous, easily-imitated actions as the MTV shows "Beavis and Butthead" and "Jackass," which explains why after Stan gives Shelley the "family love" bit to keep from getting beaten, there's a shot of Stan on the floor with a puddle of water around him (it should be noted that even though the scene is cut in America, it is shown in other countries).

Mr. Garrison: Well spank my ass and call me Charlie, it looks like we have two "A" students in a cloning war.

(Watching an elephant have sex with a pig)
Chef: Now I know how all those white women must have felt.

Stan: What about our elephant pig?
Dr. Mephesto: I'm afraid I can't do that. Haven't you heard that song by Loverboy? (Breaks into song) Pig and elephant DNA just won't splice.

Kyle: Stan, you can use family love as a weapon against Shelley. The next time she's gonna kick your ass, just tell her, "Shelley, you're my sister, and I love you."
Kenny: (Muffled) And I want to take off your bra.

Mr. Hat: I'm your friend, Mr. Hat, Stan. You can tell me anything. Now, who hits you, is it your father, or your mother?
Stan: Oh, neither. It's my sister.
Mr. Garrison: (angry) Your sister?! Oh for Pete's sake, don't be such a little wuss. Stop wasting Mr. Hat's time with pansy little foo-foo problems, and give me back my cocoa!

Dr. Mephesto: Haven't you ever heard that song by Loverboy?
