What are the odds of that happening?

Alright, we've got the calendar up to 2012, let's take a vacation. I doubt that people in some future civilization would be stupid enough to think that means the world will end in 2012. After all, future people would have their own calendar - maybe with a picture of a cat on it. Anyway, we'll continue work on the calendar later, as long as some aliens don't come across the ocean & destroy our culture.
