They showed it on TV at 8 MST but I didnt watch cause i tuned in to the Ultimate Fighter thinking they were going to Re-air the new SP episode after Stewart/Colbert like they usually do, but they didnt, I also looked on the guide for today and it looks like their not showing the new episode, damn guess im not gonna be able to see it fuuuuuck!!
Apparently it was edited quite a bit by Comedy Central on its original airing and that's why they're not showing it on their site

Here's what Trey and Matt had to say about the editing from their site:
http://www.southparkstudios.com/news/3878"In the 14 years we've been doing 'South Park' we have never done a show that we couldn't stand behind. We delivered our version of the show to Comedy Central and they made a determination to alter the episode. It wasn't some meta-joke on our part. Comedy Central added the bleeps. In fact, Kyle's customary final speech was about intimidation and fear. It didn't mention Muhammad at all but it got bleeped too. We'll be back next week with a whole new show about something completely different and we'll see what happens to it."
