According to three-strikes-you're-out televangelist Harold Camping, today is the absolutely official without a doubt painstakingly calculated and researched day the world will, in fact, end.
This article [complete with scary photo of Mr. Camping] details some of his wild ass predictions, which have become decidedly less wild since his May 21, 2011 debacle during which he had a bunch of his loyal followers so convinced they'd made it to Rapture day that they gave up all their worldly goods to drive cross country and sit at his compound to await the beginning of world-pocalypse.
They were disappointed.
The rest of us went about our lives, apparently effortlessly living through the Rapture which occurred invisibly on that predicted day. Now, with a bunch of months to churn around and really gear up for a good kaboom, the world is now fully cooked and ready to pop like a dried out corn kernel in hot oil, so pull up a slab of butter and get ready for the show.
Unfortunately, you may have to watch really closely, because not only does Mr. Camping feel "Probably there will be no pain suffered by anyone because of their rebellion against God", it's highly likely all this world-ending business will be largely invisible as well.
On the really off chance he's finally right this time [excuse me while I LMAO], I'll see you all in heaven or hell or wherever all us fun people end up. I suspect wherever it is, we'll be having a hell of a better time than Mr. Camping.
