This is not a joke. I believe I have figured out the 2012 Doomsday theory. Let's begin. Take December 21, 2012, and put it in a standard date format: 12/21/12. Look closely at the date. Yes, it does consist of 1's and 2's, but let's put those together. 1+2/2+1/1+2. Add that together, we have 3/3/3. The "/" symbol is used in math as division. Standard math, let's do it. 3/3 = 1 1/3 = .33333, repeating. The 3's are repeating. There is only one true answer. Half Life 3 confirmed.
