It's the smack that was heard all around the world. Moments before winning the Academy Award for Best Actor, Will Smith was on stage for a totally different reason.

Enraged by a joke made by host Chris Rock about his wife, Jada Pinkett Smith, Will Smith stormed the stage and slapped the comedian before telling him to 'keep my wife's name out of your mouth'.

Dermot and Dave along with producer (and telly expert) Maria Devereux looked at the lead up to the slap and debated if it has shadowed Will Smith's win.
