1) Regarding Scientology: Tommy indicated that he does not know much about Scientology. One can easily find info about Scientology online. However, if you have about 20 minutes to kill, there is an infamous/famous episode of South Park explains WHAT SCIENTOLOGISTS ACTUALLY BELIEVE. Click here for the video (requires flash).
WARNING: The characters in South Park use bad language. I do not endorse bad language BUT I did find this particular episode funny.
2) Regarding Mormonism: Here is a video explaining what Mormons believe. Nickolas, you can tell me if it's correct. And here is South Park's explanation of Joseph Smith's origins. This is just a clip, not a whole episode. Dum dum dum dum dum.
3) On an unrelated note (not meant to be humorous), Evan's brother is at Silver City.
