I watched this video and he really does scare his fans. I think he is pretending to be a wax figure, but then he comes alive or something. I think what is even scarier is when he bites off a head of a bird some years ago in front of fans.

These acts of biting bird heads (not for purposes of food) seem wrong to me. I would not bite a head of a live bird.
