Gargoyle

I SAW a mouth jeering. A smile of melted red iron ran over it. Its laugh was full of nails rattling. It was a child's dream of a mouth.
A fist hit the mouth: knuckles of gun-metal driven by an electric wrist and shoulder. It was a child's dream of an arm.
The fist hit the mouth over and over, again and again. The mouth bled melted iron, and laughed its laughter of nails rattling.
And I saw the more the fist pounded the more the mouth laughed. The fist is pounding and pounding, and the mouth answering.
