Kind of weak. Having Jerry Seinfeld as number 2 is retarded since it's pretty much known he's not actually a scientologist. As for Charles Manson, if you're going to claim that he's actually a Scientologist you're probably also going to have to claim he's buddhist. He also CLAIMED to have stopped looking into it because he reached the highest level one could, not because he thought it was crazy. Realistically, it was a fellow prison inmate who was teaching it to him, so take that as you will.
Whatever, Cracked.com really really blows. MAD wins again.
