Days after teaching Britney Spears his coveted equine dance, Korean pop star Psy is back in the invisible horsey saddle, this time performing on the “Today” show. The K-pop rapper blew up Rockefeller Plaza yesterday with his infectiously rhythmic dance hit "Gangnam Style," which most listeners agree is one part super-catchy and one part completely ridiculous. The ridiculousness, however, is nothing the rapper is unaware of. Psy himself has proclaimed the key to the song to be to "dance cheesy," and the tune's own lyrics softly mock the rich culture of Seoul's affluent Gangnam district. So if you haven't gotten on the Gangnam trolley yet, grab your fake lasso and get those hips shaking. The dance begins around 1:23.
