Just when you thought it was safe to walk into a co-workers office

You find them watching this slightly disturbing official Korean VSTS flash cartoon/song.  I'm probably the last person to see this thing because everyone I told seems to know about it.  I'm not sure whether to laugh or cry, but I do know that I'm going to steer clear of any office I hear that song coming from. BTW - The rough translation is available on the page as well.
