Honestly, this is exactly what it sounds like...so you should probably skip the next few sentences and just watch this German family murder LL Cool J like no one else could. So much fun these Germans have!
OK, fine, I'll give you a better description. But, since I am not that good at describing that which cannot be described I'm just going to paraphrase Sara McLachlan's "Building a Mystery": This video is a beautiful, fucked up mess. (Also I just realized that the lyric is "beautiful, fucked up man," which I guess works, too.)
