This bit of Mayan humor goes right along with the news that the earliest known Mayan calendar shows no hint of world's end. Archaeologist William Saturno of Boston University said, "We keep looking for endings. The Maya were looking for a guarantee that nothing would change. It's an entirely different mindset." All that is supposed to end in 2012 is one of the Mayan calendar cycles. See Wikipedia @ http://en.wikipedia.org/wiki/Maya_calendar.
This, of course, is an alternative understanding for Americans who "watched the ball drop" on many a New Year's Eve and already miss Dick Clark.
