End of the World, 2012? WTF

What the hell is this all about? Many people have mentioned it recently. I really don't have the tolerance to get too far into it. Frankly it's just disturbing for me to think about. Even right now on The Daily Show there is a man talking about an asteroid hitting in 2029. Guess that is kinda comforting though because that means he doesn't believe the 2012 theory. Hm...
