The guy who dresses up like Deadpool and goes to all the West Coast comic/otaku events took time to do the best parody of a music video in Little Tokyo. This is the second Gangham related thing I've posted on in just a few days.
I'm unsure, but there are some other locations other than Little Tokyo in the video, one has to be a college campus and one of them is Westfiled mall. Also, some sort of playgound? Try and name them in the comments.
I'd guess he'd be at Comikaze Expo this weekend, give him a hug!
