OMG. These guys are my new heroes. It's along the lines of the Numa Numa song that was out a few months back. The guy in the background who seems oblivious to all the commotion cracks me up. Apparently you can use Google to search for videos and that's how a friend of mine found this.
UPDATE Nov. 28 - I found out who these guys are! They're majoring in sculpture at the Guangzhou Arts Institute. They have a blog but it's in Chinese.
