"Fifty Shades of Grey"-mania has even taken over the stars of CW's Supernatural! During a panel discussion last weekend, Richard Speight, Jr. and Matt Cohen took to the popular book for a some impromptu theatre.

At a panel discussion held during Creation Entertainment's "Salute to Supernatural" event, the two stars snagged a copy of the popular "mommy porn" novel from the crowd and interpreted scenes to the shock and delight of the crowd.
