The movie's subtitle: South Park: Bigger, Longer & Uncut. At first, people think that Matt Stone and Trey Parker added that tagline to give the movie its uncensored/unrated status (it was originally going to be called South Park: All Hell Breaks Loose, but either the censors didn't approve of it or the creators wanted a better title), but really it's a penis joke (the "uncut" refers to a penis being uncircumcised).
Is it really considered Brilliance if that's the point of the joke? Especially for regular watchers of the show...
In "It's Easy, M'kay?" Mr. Mackey suggests to the kids that instead of saying Fuck they say M'Kay. Why is this important? Think about this: He considers M'Kay (his Verbal Tic) to be an equivalent of Fuck, so in his mind he's constantly swearing at children and his superiors!
When Mr. Mackey tells everyone over the PA that anyone wearing wearing Terrance and Phillip shirts needs to go home, Kenny runs out with the rest of them despite being dressed in his usual outfit. Kenny just wanted to leave school with his friends, he took advantage of the situation.
The scene where the general executes Bill Gates for Windows 98 fucking up after Gates had told them it would be faster, more efficient and with better access to the internet. Gates was telling the truth, the computer only failed due to Saddam Husseins interference from Hell. Bill Gates was killed for something that wasn't even his fault!
Kenny saw and eventually entered the Muslim version of Heaven, since there were 72 virgins waiting for him.
Kenny sees Mahatma Gandhi upon entering Hell. Since this is the Christian version of Hell, Gandhi was being put there for being a heathen presumably. Also, later South Park seasons show that only Mormons can enter Heaven anyway.
A little-known fact about Gandhi is that he abused women, which, in this fictional afterlife, would likely influence where he went.
If Sheila and the rest of MAC went through with their plan of putting V-Chips in all of the kids of South Park after seeing its success with Cartman, what if the kids with V-Chips just so happened to say a colorful metaphor while they were out swimming or taking a bath?
Being electrocuted would likely produce more obscenities, meaning that everyone in the pool would die, including those who werent actually swearing. One of these moms would walk outside and see these kids floating in a pool, dead. Theyd probably blame Canada.
