As you've certainly heard by now, the world is ending tomorrow. Thanks to infallible Mayan prophecies and/or calendar design, we know the whole shebang comes to a hard stop on December 21, 2012. What our helpful future-seeing friends didn't see fit to tell us is how the world ends. Sure, you could argue it doesn't matter -- dead is dead, after all -- but the fact remains that, damn it, we want to know. Since we don't have the powers of prognostication that our long-gone Mayan pals did, we have to rely on our usual methods of figuring stuff out: drawing on years of pop-culture consumption and filling in any holes in our knowledge with a trip to Wikipedia.

That done, we've assigned odds to the various doomsday scenarios, in case you're the betting type -- although you're going to need to survive to collect and money will be useless in the post-apocalyptic wasteland, anyway. Maybe you can place your bet in canned goods and toilet paper?
