So, Oct. 21 is the new Rapture. Right.

On Friday, Oct. 21, 2011, the Rapture will be upon us. That's according to U.S. Christian broadcaster Harold Camping anyway. Yes, that's the same Mr. Camping who "predicted" doom on May 21. But, as far as I'm aware, we're still here. So, Oct. 21 is the new Rapture. Right. Postponing doomsday is not uncommon amongst doomsayers (religious or otherwise), especially when the original day of doom doesn't happen. And for Camping, "Doomsday Deferral" seems to be a fun trick he likes to play. He did, after all, also predict doomsday in 1994.
So, how did the ailing 90-year old explain away May 21?
