I'd say "David Bowie and David Hyde Pierce fused together in a teleporter accident."

This terrifying dude right here is allegedly the friend of one redditor slupo, to whom he supplied this personal photo and the one below. I know what you're thinking: is he going to jump through the screen and kill me, or what? Surprisingly, no. It turns out that this mad scientist/inappropriate teacher/crooked cop is actually an acting teacher, and as far as I can tell, not a murdering one.
