Inspired by ABC's Shaq Vs, James Franco decided to spend the day challenging members of the entertainment industry at their own crafts.
He wasted all morning trying to convince John Mayer to participate in a guitar competition, but Mayer politely declined.
Franco then tried to challenge Chris Rock to see who could come up with the best YO MAMA joke. Rock was confused by the request and couldn’t understand why his mother was being verbally attacked by the guy from Pineapple Express.
In the late afternoon, Franco was finally able to convince the rapper Common to square off in a rap battle. The battle went down inside a small bar in the heart of Brooklyn. It turns out Franco is a horrible rapper – he was practically booed off stage. Nevertheless Common was excited to have participated and looks forward to doing it again.
