Just when you thought Gangnam Style might have peaked, it gets a boost from Chinese dissident artist Ai Weiwei, who has released his own version of the hit South Korean pop song on YouTube, with a decidedly political edge. The NY Times explains:
The artist, who mimics the mock horse-riding dance moves of the original while wearing handcuffs in his remix, calls his version “Grass-Mud Horse Style,” a reference to a Chinese Internet meme that employs a pun on an obscene phrase to mock government censorship of the Web...the grass-mud horse is “a mythical creature whose name, in Chinese, sounds very much like an especially vile obscenity.” Chinese bloggers invented the alpaca-like creature to demonstrate the absurdity of censorship by embedding foul language in an innocent-looking video for a children’s song about its adventures.
And if you're curious about that 'obscene phrase', this video explains.
