In case you were wondering...

Instead of most people taking this whole 21/12/12 theory with a pinch of salt (no, not the bath salts that make people turn into 'zombies' and eat people's faces: http://ieweekly.com/2012/11/feature-stories/bath-salts-the-new-hard-drug-or-just-something-for-the-youngsters/), many people have seemingly been taking it so seriously that NASA have felt to obliged to add a FAQ for "Will the world end in 2012?" to their official site - http://www.nasa.gov/topics/earth/features/2012.html 

Sigh.
