LMFAO Mash Up Video With North Korean Army [VIDEO]

I will start off by saying this isn't politically correct but interesting though.  Billboard.com has named LMFAO's "Party Rock Anthem" as the song of the summer and it's got a new video featuring Kim Jong-il's Korean Army.  The video features the army marching to the beat of the song along with images of children performing dance routines and some scenes of North Korean's dancing.  Although their leader is very stiff.  Check out the video after the jump and let me know what you think of it.

Now at 3:49 in the video is what I don't understand.  What is Kim Jong-il doing?  Yes, they are cabinets and a sink and water runs in both sides of it, I just wonder what this video footage is from.

Let me know what you think.  Leave your comments below.  By the way the official video is below too for you to check out!
