What's The Purpose For Planking?

According to wiki "Planking" is the act of lying face down with arms to the sides of the body, in unusual public spaces and photographing it. The term "planking" was coined in Australia and became a "Fad" in 2011.  Some people  are saying "Planking" has it roots in slavery I'm sorry  personally   I don't believe that  to be true. Nor do I  see a connection in any way to slavery.

I’ve seen a number of pictures all over facebook, and it makes me wonder what is it  about us humans and our culture that makes us craves this kind of silliness and foolishness?  So when I found a pic of Gospel Rapper Lecra  partaking in this foolishness I'm thinking what is it that  make  people act the fool?  There's nothing wrong with it!! Neither is there any redeeming  purpose  for it either.  I don't have anything against it but  I’m just wondering what gives? When you find Christians following the world with this kinda foolishness you have to ask what gives? Again there is no religious, political,  economics nor social purpose in this act at all. So what's the purpose for Planking?
