Voting with His Feet
"This is the farewell kiss, you dog!" Iraqi journalist Muntazer al-Zaidi shouted at George W. Bush during a press conference on Dec. 14, 2008. Al-Zaidi then hurled his shoes at the startled U.S. President — a gesture embedded with great scorn in the Arab world, where the act connotes extreme disrespect. Bush, who narrowly dodged the flying footwear, brushed off the insult, but Iraqi security forces weren't so forgiving, beating al-Zaidi brutally. The stunt made international headlines and turned al-Zaidi into a hero in the eyes of many. It even spawned copycats: less than two months later, a Cambridge University student, Martin Jahnke, lobbed a sneaker at visiting Chinese Premier Wen Jiabao.
