That's just crazy talk! I don't think that anyone who gets raptured would deny they are being raptured, would they? I mean, how could they?
I was thinking earlier, just because this guy (Camping, not Thor) is a complete whack job and is making these predictions based on idiocy doesn't mean that the rapture couldn't happen when he predicts. It certainly wouldn't be for the silly reasons he's putting forth. It would be more whacky coincidence.
