So you've already picked out your PSY Halloween costume, you've been practicing the pony dance, and you're well-versed in the subversive message of "Gangnam Style" but here's one thing we're betting you new K-Pop obsessives haven't done: watched Ai Weiwei's parody video. Labeling his version "Caonima Style" or "Grass Mud Horse Style" (which, along with a shot in handcuffs may reference a frequently-incorporated protest symbol meme), the celebrated dissident Chinese artist recorded and tweeted this clip of himself getting in full-blown PSY mode with some friends, in-between shots from the actual music video. And you know what? He's got some moves! Well...kinda.
