If you thought you were going to get through the day without experiencing any 'Gangnam Style,' think again. Here's video footage of Psy rising onstage from underground at Madonna's concert in Madison Square Garden last night. The two do a little 'Gangnam Style,' then there's a slightly awkward interview in which it seems Psy is completely unfamiliar with Madonna's entire body of work. Just kidding you guys, of all her songs, he somehow knows the words to 'Music,' and now he's going to grind on her 54-year-old body in front of everybody to prove it, which is awkward in a much different way. Enjoy?
