Rapper turned actor Xzibit sees nothing funny about planking, the latest trend that seems to have swept Hollywood in the last few weeks. He wrote on Twitter:

Planking is THE dumbest sh-t ever. #Planking was a way to transport slaves on ships during the slave trade, it’s not funny. Educate. Don’t get it twisted. I care less where your dumb asses lay face down and take pictures of the shit, I’m just telling you where it came from.

Among many others, pictures of Rosario Dawson, Ellen Page, Justin Bieber, Katy Perry and more “Planking” have hit the net in the past few weeks. Check out a ton of pics of celebrities planking below:
