Will Smith smacks Chris Rock in the face

During the Academy Awards ceremony, Chris Rock was on stage when he then made a joke about Will Smith's wife shaving her head. Will at first laughed at the joke but then his wife looked at him and he went up on stage and hit Rock right in the face. Chris Rock refuses to press charges on Will Smith. Many people think what Chris Rock said was wrong but Will Smith quite clearly overreacted to this 'joke'...
