“He wanted to knock these humans’ heads together and toss them out of the suite, preferably out the window.”

“He smacked the heel of his hand against his forhead, as if that could knock the mental picture out of his head. Hell, he though irritably, he didn't want to knock the image just out of his head. He wanted to send it clear across the room and out the window.”

“He had an extraordinarily casual air about him. I'd noticed that before, when he had tossed himself out the window.”

“He grinned, making sure to flash his straight, gleaming teeth, every last one of which I wanted to knock out of his head”

“You don’t let them knock you out, you make them knock you out. You make them break their fucking hands knocking you out, you let them know that they’ve been in a fight, you give them something to remember you by every time they look in a mirror.”

“Do not think of knocking out another person's brains because he differs in opinion from you. It would be as rational to knock yourself on the head because you differ from yourself ten years ago.”
