Since it was staged maybe he had a stunt double asshole. I know what you mean about listening to yourself. I would rather watch an ISIS beheading than that.
He's fucking insane. Does the stupidest shit for effect but it doesn't even phase him. He pretends it does for the camera.
That strain on his face trying to shove that plastic pipe up his ass sure looked real. Kinda hard to fake that even if it was for pleasure.
He does that when doing any stupid stunt. He's not human so he pretends to be bothered. He prolly does that everyday for fun.
