I agree with most of your assessment of South Park. However, I have to disagree about the Imagination trilogy. While as a narrative, it didn't really go anywhere it had the best and most pop culture references I've ever seen. Seriously, I mean part 3 had ROM the Spaceknight, part 2 had a prolonged Stargate reference AND Manbearpig, and part 1 had the funniest joke they've ever done (which of course was the Butters/rape joke which still makes me wet my pants). Now that I think about it, Butters is probably my favorite character in any show ever. Including my favorite show, Futurama (end of the month, new movie!!!).
As for this week's episode, I didn't think it was as similar to the WoW episode as you. I thought it was more a parody of rock bands/musicians (Behind the Music) and the fact that the kids thought game was cool, the actual music not so much. I mean, they kept making heroin jokes (chasing the dragon was fantastic).
I used to watch the Fox sunday cartoon/whatever block, but i really don't care that much anymore. With the exception of King of the Hill, which I still think is the superior sunday show (right now).
