Its amazing how much being a good actor lets you away with being a tosspot. Cordon was right, Stewart called him out tried to show him up and Cordon defended himself by making a fool of Stewart which he did. The Becker video is clearly James after having a few drinks and being egged on by mates (The Brawn Team) and just having a laugh. Stewart should have accepted his award or whatever he was doing and walked off stage.
Both acted like tits and both were not funny. Corden shouldn't have been standing the way he was and Stewart shouldn't have reacted.
