Sometimes you can find one of those brilliant Apocalypse 'documentaries' on the History Channel where some somber narrator enjoins you to watch dubious theories without much backed-up evidence and last night was no exception - apparently Isaac Newton believed in a bible code that predicted 2060 as the end of days.
My favourite though has to be the Mayan Calendar.
According to the theory, because the calender ends in December 2012, then that is when the world will end...
I reckon it was simply some junior civil servant finally having enough of the pointless task in front of him:
"Why are we doing this calendar? We're already up to 2012, it's ridiculous. That's it, I've had enough, I'm off to the Slaughtered Llama for a beer!"
