Well, at least the things he believes in are tangible things. The 9/11 one isn't even crazy, it's just almost certainly not true, George W.

I always get Scientology mixed up with Mormonism. One of them, whose core belief is this fruity science-fiction monstrosity of nonsense that's more scientifically illiterate than star trek, far from having the details of its origins lost to the mists of time, was historically provably invented recently by a known con artist for the purpose of getting a bunch of money out of suckers, and requires you give the church lots of money. And the other, well.... wait. Which one was I talking about again?
