Ah! The old 2013 iMac trick!
SHJ said
"The 20th of December, that is one day before the end of the world according to the Mayans"
Just because some old Mayan priest said "Fcuk this, I'm not carving any more predictions, it's time to stop!" Throws down his chisel and the stone says Dec 21st 2012 and millions of present day stupids think that means an end to the world and and all it was was the end of the stonemason's elbow that the Priest had been getting for carving some future unverifiable stone chipped decades.
