We should all start making brew shelters and stock up on homebrew. Something tells me it'll be hard to get malt after the apocalypse.
On the other hand, before that, the apocalypse was in 2008 and in 2000 before that so... Just because Mayans' Calendar is ending, does not necessarily mean the world is ending.
And I don't think world apocalypse is a very good one for the end of the world. It is derived from greek Apokalipsis which means "Revelation."
