Maximum the Hormone - Zetsubou Billy

I've already posted this guys once. Was listening to a J-Rock album a friend of mine got me, and I still feel that these guys are one of the best J-Rock bands I've listened to so far.
The video is a parody of the clichet videos made in Japan. Around the middle, the band shows itself as they are.
Once again, it's an anime theme song. Anime really moves a lot of money and influence in Japan!
