WASHINGTON: Chinese dissident artist Ai Weiwei hopped onto the "Gangnam Style" bandwagon Wednesday, posting his own parody of Psy's viral hit that remained at number two on Billboard's Hot 100 for a fifth week.

Ai, 55, banned from traveling abroad, joins the likes of hipsters, flash mobs, prison convicts, wedding parties and, on Tuesday, UN Secretary General Ban Ki-moon in mimicking the South Korean rapper's signature pony dance.
