"Religion"

What if people just started religions based on anything they wanted? Oh, wait. They already do. Some of them. Or at least it seems that way. Then again, maybe some of these religions we laugh at only seem silly to us because they haven't been around nearly as long as the established ones like Christianity, Judaism, Islam, etc., and aren't nearly as popular, so they don't have the same credibility yet. Anyway, I was reading a user comment on imdb (the Internet movie database) recently, and someone wrote that she was starting a religion based on the movie "Supergirl." I hope she was kidding--but I'm not sure. Actually, it's much funnier--though scarier--if she's not kidding. Kara, the Supergirl character--is the "goddess' of this "religion." Basically, the premise is that all the followers worship Kara and her perfect ways, and basically that acting like Supergirl is what everyone should do. What if this person took this thing to the next level and actually got converts and followers? And they had actual meetings? What would they talk about?
"I tried to fly like Kara today...it didn't work out. Yes, that's why I'm in a wheelchair. Kara be praised."
"I'm still trying to figure out where that darn magic orb is that was stolen from Krypton. it's somewhere here on Earth."
"Keep looking, Susan. Don't give up. Kara is with you."
"Today, I tried to stop a car full of bad guys fleeing from the cops--that also didn't quite work. Would everyone please sign my full-body cast? Oh, just not across the chest--that spots reserved for Kara's signature when she returns."
Maybe there's a rival religion that worships Lex Luthor. The goal is world domination--and thwarting the efforts of the Kara-ites, of course. Followers of this religion would all be completely hairless, of course, like Luthor. They'd probably have ritualistic hair removal procedures.
