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).

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