So a very political-minded Chinese artist named Ai Weiwei made his own "Gangnam Style" video in which he kinda sorta hinted — with handcuffs — that the Chinese government wasn't very nice to him. Like that time they arrested him. Boom, his video is gone. So then his buddy, artist Anish Kapoor, organized a mega-music-video protest! Note the handcuffs and a brief glimpse of Weiwei himself in the opening seconds. Watch it, yell "Booyah!" at your screen, and then share it if you're into freedom of expression.
