You don't think people will do crazy things on the day we have all been waiting for our whole lives?
I imagine there is going to be a lot of out of the ordinary things happening, A little terrorism, some bankers getting charged, and a lot of the worlds insane killing themselves and there we have "the end of the world as we know it"... even if it is only slightly different :p
