1 mistake in Fat Butt and Pancake Head - chronological order
Starring: Trey Parker, Isaac Hayes, Matt Stone, Mona Marshall
Scott: All of these things link Terrance to the murder: hair fibers, blood samples, nail clippings, a piece of his shirt, a watch with his initials on it, a day planner with the murder scheduled, a haiku called "Time to Kill Dr. Jeffrey O'Dwyer": Dr. O'Dwyer, time to have your head smashed in with my new hammer. Terrance, you may be a famous surgeon, but you're not God. J'accuse Terrance.
Trivia: The creators of the show, Matt Stone and Trey Parker, based the Stan Marsh and Kyle Brosfloski characters after themselves (Stan being Parker and Kyle being Stone.) The Eric Cartman character was partly based on Archie Bunker.
Question: Forgot the episode and the season, but does Mark, the kid that gets home schooled and ends up beating Kyle, ever show up in later episodes?
Answer: He appears in at least 5 other episodes, but usually just as a background character. He can be seen at Cartman's party in "Immaginationland". He was also one of the kids trying out to replace Butters in the "Professor Chaos" episode.
