Reminds me of a text Batman/Joker story (Tales of Batman? Tales of the Joker) where as part of his plot, the Joker kills a couple of rich eccentrics by cutting their faces off on live TV, but does it so he's facing the camera and the victim is strapped to a chair facing the Joker, so the viewing population don't see anything specific but it's left to their imagination with the sound effects.
And then, with ghastly mental imagine playing in their heads, the Joker peels the face off and tucks it nonchalantly into his suit pocket like a handkerchief.
At that point I think I threw up in my mouth a little, damn this imaginative minds eye of mine!
