Mayan apocalypse- remember Y2K?

There is all this bunk about the Mayan calendar ending in December of 2012, and therefore the world will end in a fiery ball of wonder.

I say BAH! First off:
How the heck did those Mayans know about the roman calendar anyway? Do they count Leap years?
Second off:
What do you do with your old calendars when the date runs out on December 31st?
Third off:
Remember all the hubbub of Y2K? Yeah? Really?

Again I say -BAH!
I truly think that we will wake up in January of 2013 and start it all over.
