Coozer Prophesy: Is 12/21/12 the end of the world?

I'm getting really, really drunk on December 20, 2012. From CNN:

Fueled by a crop of books, Web sites with countdown clocks, and claims about ancient timekeepers, interest is growing in what some see as the dawn of a new era, and others as an expiration date for Earth: December 21, 2012.

The date marks the end of a 5,126-year cycle on the Long Count calendar developed by the Maya, the ancient civilization known for its advanced understanding of astronomy and for the great cities it left behind in Mexico and Central America.

(Some scholars believe the cycle ends a bit later -- on December 23, 2012.)

Speculation in some circles about whether the Maya chose this particular time because they thought something ominous would happen has sparked a number of doomsday theories.
