Here it is, the whole episode:

...it`s one of the funniest Sout-Park-episodes ever, I laughed till I dropped. But just one thing: In the middle of the episode, theres this montage about "what scientologists really believe", and it`s a really, really crazy (and I mean really about-time-to-be-hospitalised-in-a-psyche-ward-crazy) science-fiction story about aliens and their souls causing depression in humans and oh my God, it`s so crazy it makes the WTS look really sane! And please tell me: This is not what scientologists really believe, is it? Cause if it is, I`ll never watch a Tom Cruise or a John Travolta-movie again.
Ps. I put it here in in the Beliefs-section cause I wanna know if this is what scientologists believe. If they believe what the SP-episode says, then holy, holy crap, holy mother of all crap, they`re all insane!
(oh, and btw: Tom Cruise tried to stop this episode, ha ha)
