Video: UN's Ban Ki-moon dances Gangnam Style with K-Pop's Psy On a visit to the United Nations (UN), South Korean rapper Psy attempted to teach Ban Ki-moon, a South Korean, his popular dance from the video of Gangnam Style. Admitting at first that he was "nervous," the UN Secretary-General relented and copied Psy's horse-riding style dance moves. Psy was at the UN to discuss with Ban Ki-moon how they could work together to help global issues. Earlier, Ban Ki-moon had joked: "I was thinking about you when you were coming - you know we have tough negotiations in the United Nations. In such a case I was also thinking of playing the Gangnam Style dance so that everybody would stop and dance, maybe you can bring UN style. Psy's song Gangnam Style, which mocks the consumerism of a rich Seoul suburb, and his hit horse-riding-style dance went viral on video-sharing website YouTube. It has been viewed more than 560 million times since it was released in mid-July.
