Just got schooled!

So last week I posted an article on PSY's new epidemic song "Gangnam Style". I know I mentioned that Big Bang's Seungri and Daesung were spotted in disguise in the background dressed as two older men. Now the only reason I was able to display this info is not because I was able to recognize them, it was because this info was released to the public about their partaking in the video. As for Hyuna I didn't feel there was any need to mention her... I mean she was in plain view. But something I failed to notice and to look into was the strange man in the yellow suit who has a dance off with PSY.
