Planking

"The lying down game is an activity consisting of lying face down in an unusual or incongruous location. The hands must touch the sides of the body, and having a photograph of the participant taken and posted on the internet is an integral part of the game.  Players compete to find the most unusual and original location in which to play. The location should also be as public as possible, and as many people as possible should be involved. It is known as "Planking" in Australia and New Zealand."

A friend and coworker asked me one day last week if I'd go planking with him.  He was just being stupid, but knowing that he's out during a half day each week, I took the opportunity to plank without him.  In his cube.  It was surprisingly uncomfortable, but I didn't fall to my death like a Kiwi, and I think the developers in his area were highly amused.
