Perhaps the only Skeletor and the Boners blooper footage ever captured, this short video will undoubtedly spawn discussion, argument, and controversy among rock fans for decades to come. 

As mysterious as it is intriguing, the clip features the band referred to as “the Godfathers of Evil Metal” apparently shooting their much anticipated music video for the song, Bloodfeast. After the lead singer inexplicably begins laughing, ruining the shot, we see a hairy, bare-chested man enter the frame from below. Who is this man? Where did he come from? The world may never know.
