There is not much else I can say to introduce this clip other than "Here is a video of Karateka characters singing and dancing along to Michael Jackson's 'Bad'." You can skip to 1:20 for the "Bad" portion, but the intro (and end credits) is quite entertaining, too.

I can't tell you what posessed Youtube user Koi72 to match this 27-year-old-game's visuals with this song, or why I enjoy this so much, but I can say that he created this with the MikuMikuDance software -- so, grab that, create your own dance video, and send it over!
