So put your head between your legs and kiss your **** goodbye although to be honest I doubt they'll have got the date correct.
The current speculation is that tomorrow is the end of the world as fortold by the Mayan calendar which gives 21.12.12 as the end of the 5th sun. This unfortunately assumes we knew when the first sun was born and have counted accurately ever since. Given that the calendar has developed from before Egypt through the Romans to the current day with Popes moving days and Roman Emperors adding days having originally fouled up by not starting at zero (see this link for a summary) then the chances of anything happening tomorrow seems slight and most commentators speculate that the meaning of 'end' has been misinterpreted.
Given that though, the first four Mayan suns representing fire, air, water and earth (as in most civilizations) generally concluded in flood and fire so I look out of the window at the pouring rain and wonder. Oh bugger it, at least I won't have to buy any presents!
