The short version of what he believes is we are in the Matrix. If he jumps from a certain cliff on 12-12-2012 at 11:11 am then he'll stop the program from shutting down. And that he'll land safely.
Hopefully there will be a news crew there to watch. I want to hear him declare how stupid he was when he breaks both his legs.
Was it Doomsday Preppers? Because most of them are certifiable.
No, not Doomsday Preppers, though I have seen a few episodes of it. I think it was just called Doomsday 2012. Kind of a one-shot deal. One guy said that the Mayan calendar has hidden calculations to prove there will be massive solar flares, which are supposed to reverse planetary rotation. A couple of people were claiming that Nibiru is causing global warming and it's going to get worse as it gets closer (shouldn't we be able to see it by now?).
