Al Sharpton joined Jon Stewart on The Daily Show tonight. When the subject turned to Occupy Wall Street, Sharpton expressed his support for the movement, but Stewart wasn't quite as enthusiastic, taking issue with some of the protesters' attention-getting theatrics. Stewart also wondered about where Occupy Wall Street goes from here. "What they've done there is so unusual that it can't be ignored," Stewart started. But now that they've managed to capture the world's attention, we're left asking, "When are you going to change the world for us?"
