Why is Scientology so determined to keep a nine-minute video under wraps? At least that's the question buzzing the blogs. The video, which features a manically laughing Tom Cruise rambling about the wonders of the "religion," was leaked on YouTube this past Monday -- but was quickly removed.

In the bizarre clip (complete with eerie "Mission: Impossible" music), Tom goes on and on about how Scientologists are the "authorities on the mind," and utters inside Scientology lingo -- like "SPs" and "KSW" -- code the Church probably doesn't want non-members to hear.
