Jon Stewart

Jon Stewart may be one of the hardest working men on television, but it looks like he's about to take a break from hosting 'The Daily Show' for a few months. But he's not going on a vacation: he's going to direct a movie. 'Rosewater' will not only be Stewart's first time behind the camera, it will be something completely out of his regular wheelhouse.

Over the years, Jon Stewart has had many actors as guests on 'The Daily Show' but there's one person Stewart says will never return to his stage. Who is this person and what did he do to piss of the 'Daily Show' host and his staff?

Neil Young had to reschedule Wednesday night's planned Twitter chat when he realized he was supposed to be a guest on a popular talk show.
