It's not a 'stunt'. The Mayans believed the world would end on 21/12/12 and have made detailed descriptions on just what will happen so no-one can escape. However, they didn't include leap years so we're actually in 2013 by the Mayans' calendar, so the date has already passed.It shall not happen. only fat head jocks believe in this utter pathetic stunt.
Anyway, given that most people will be doing something related to mocking the end of the world, i'd love to join in with the 'final hours' thing, so long as i remember and my parents allow it.
