1. Fishsticks (Season 13, Episode 05)
It made a pretty lame joke seem funnier than it has the right to be, but this episode was a return to form after a largely disappointing season 12, and the absolute best from season 13, before they flopped again for the first run of the next, season 14.
An episode of South Park can easily derail when Cartman has no redeeming qualities (e.g. adventure spirit) to balance his evil side, and this is who he has been for most episodes since the end of Season 12 or so, i.e. a plain and stupid, one dimensional villain who barely has a good one-liner. With Fishsticks however, they achieve a balance to absolute perfection: with the help of Cartman himself who is now just a messenger or at worst the emperor with no clothes, an idiosyncratic rapper reaches an epiphany of religious proportions.
"Some people just have egos that are so out of whack that no matter what people tell them, they can't accept the truth of who they are" -Cartman.
Because no else will, the “voice of a generation” takes it on himself to put aside Ego (which in South Park is as good as Celebrity), and starts to “believe what people tell him.” In the end, he accepts his fate like a true hero, without hesitation discarding his former self to forever linger in his natural habitat and mix with his own kind. The suggestion of all this ridiculousness, if you missed it, is that Kanye is the archetype of FAIL for rap music in the mainstream eye, one of the last in the line from P Diddy to Fiddy Cent. To be fair to the man himself, he’s so easy to make fun of because he’s actually sincere in a roundabout way: that kid in class that acts like a big deal to hide insecurities, but who you know is harmless.
"I'm a genius, alright? I'm the most talented musician in the world. If I was a homosexual, or a fish, I would know!" -Kanye West
"Don't you get it? Please just get it." -Carlos Mencia
