I once ran across a website that had compiled alot, if not all, of the 'end of the world ' dates since the beginning of civilizations.
You could read about the group/cult/religion, what they believed, and most amusingly what they did when the date came and went without global incident.
It also pointed out how the smarter ones eventually went to a 'can't tell you when, but it's soon' policy. (or 'we know but we ain't telling')
Century and millennium marks are always the most popular picks.
Was hours of fun reading!
I personally am putting in a leave slip for December 21st 2012. Just in case those crazy Mayans are right.
