Jon Stewart, the 15th season overview

Because most of us have completely forgotten Jon Stewart -- what he looks like, what he used to do, even who he is -- Comedy Central has posted this four-minute overview. It's helpful. He  returns tonight to "The Daily Show" after a three-month break to direct a movie in the Middle East ("Rosewater," based on the book by Maziar Bahari). And don't forget this either: "The Colbert Report" is back after a break, too.

Jon's first quest: Andrew Harper, Head of the UN Refugee Agency in Jordan.
