49 hoaxes (like the myth of "Pope Joan") that some people actually believed

A weekly show hosted by John Green, where knowledge junkies get their fix of trivia-tastic information. This week, John looks at some of history's greatest hoaxes including "Balloon Boy" (the boy, by the way is now in a metal band), "Lonelygirl15" and "War of the Worlds" (you didn't think we could do an episode on hoaxes and NOT include it, did you?).
