The thing I like most about Scientology is that they have been found to be a completely criminal organization in much of Europe, had no end of legal troubles in the States (Operation Snow White comes to mind) and are called out for their activities all the time by ex-members.
The thing I like only slightly less than that is that this clandestine group does all this because they believe that an evil alien overlord brought a bunch of dissidents to Earth, put them at the base of a volcanco, then blew up the volcano with nuclear weapons. The souls of these aliens haunt us to this day.
And people say D&D;players are weird.
