Planking

I was just watching the new episode of the Office, (Which was great by the way) and in the beginning of it they were all planking. I really don't understand the obsession with planking. I mean it looks kind of cool but how did it ever become this big? What I really want to know is how did it even start. Did someone really just think "Hey, I bet it would look cool if I lied flat like a plank and took a picture"? Alright, so I understand some planking, but some people are just stupid about it. Is it really worth your life just to get a picture of you planking in a cool place? I don't think so.

Oh well, if they were stupid enough to do it, the least we can do is enjoy it:
