This is the first comic of the new year! And what better way to welcome 2012 than by referencing the Mayan Prophecy?
The Mesoamerican Long Count calendar (also utilized by the Mayans) runs in long cycles, one of which ends on December 21st 2012. Of course, this is just the end of a "world age" in their calendar. More optimistic individuals would believe a new age follows, but the pessimists (and conspiracy theorists) have warped this into an apocalyptic prophecy.
