mystery of quote solved

So here is J.'s version on how you could slap the head off a person's face.
In a demented way it does make some sense:
Instead of a rubbery face that got knocked out from a blank beige head, you have a head rolling off leaving a layer of flappy skin precariously dangling onto the rest of the body.
Oh gosh typing this down gives me the shivers...I prefer a blank beige head, its cuter in a cartoon-like manner
