OK, now you have all had a go at the planking craze, and to most it is harmless silliness of the younger generation, if performed safely.
Now to all you others who have dubbed this to be the stupidest, unsafest and ridiculous thing you have seen.
"Fess up", what dangerous and stupid things did you do when you were young and no one was looking.
Well I rode untamed horses, through the bush, bareback when I was 12 years old, with my older brothers. Made cubby houses in the bush, got tied up inside, and my brothers torched it,

and then rescued me whilst playing Cowboys in the Bush.
Made canoes out of old sheets of Galvanized tin and paddled around the two dams we had and sunk many, and I could not even swim then.
Now you guys have a go.
