- Beam Me Up, Scotty!: Cartman doesn't say, "No, Kitty! That's a bad Kitty!" in this episode. He actually says "No, Kitty! You bad Kitty!" and "No, Kitty, this is my pot pie! Bad Kitty!" He does say it twice in "Cartman's Mom is a Dirty Slut", however.
- Keep Circulating the Tapes: In 2009, South Park Studios hosted an updated version of the unaired pilot from mid-August to mid-September. This version was significantly different from the original release. Changes included removing all of the piano music, some new and changed dialogue, most of Karri Turner's clips being redubbed by other actors (including one instance where Trey Parker voices Liane Cartman), and more profanity. Since it's original hosting, not a single copy of this version has surfaced online. A list of it's changes is available, however.
- The Other Marty: The unaired version of the pilot had the female characters voiced by Karri Turner, as opposed to Mary Kay Bergman. Turner was let go for the final version, as the creators felt that her voice wasn't distinct enough for the characters they'd wanted her to play.
