Factual error: Kyle says he has to log on before school. The next shot shows "Monday 8 days later." 8 days before is a Sunday. (00:04:45)
Kyle: Cartman, you have such a fat ass, that when you walk down the street people go, "God, dammit thats a big fat ass!'
Cartman: They do not!
Random guy: God Dammit, thats a big fat ass!
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.
