Hillary Clinton had to be fast on her feet during a speech in Las Vegas today. A woman in the audience chucked a shoe that whizzed past her head, reports the Las Vegas Sun. "Good thing she didn't play softball like I did," said Clinton, drawing laughter. The unidentified woman apparently threw a stack of papers, too, before being escorted from the convention to face arrest, reports the Review-Journal. Clinton was speaking before the Institute of Scrap Recycling Industries, and the woman wasn't part of the convention, says a spokesperson. It's unclear at this point what prompted her protest. "My goodness, I didn’t know that solid waste management was so controversial,” said Clinton. (Click to see George W. Bush's famous close call with a shoe in Iraq.)
