Chinese dissident artist Ai Weiwei is the latest to go "Gangnam Style" — but in a trademark act of cheeky irreverence, he's thrown in a pair of handcuffs and a poke at Chinese censors. In a video posted on YouTube and Chinese websites, Ai sports a neon-pink T-shirt, black jacket and dark sunglasses and energetically mimics rodeo-style dance moves made famous by South Korean rapper PSY, whose original video became an Internet sensation. Ai says he and several friends made the video Wednesday and uploaded it overnight. In one scene, he swings two pairs of handcuffs while dancing. The video is titled "Grass Mud Horse Style," in Chinese, a sly insult Ai coined as a stab at the country's Internet censors. The Chinese characters are homonyms for a vulgar slur.
