[to Dr. Zaius after he finds a lobotomized Landon]
George Taylor: You did it. You cut up his brain, you bloody baboon!
Dr. Zaius: Dr. Zira, I must caution you. Experimental brain surgery on these creatures is one thing, and I'm all in favor of it. But your behavior studies are another matter. To suggest that we can learn anything about the simian nature from a study of man is sheer nonsense. Why, man is a nuisance. He eats up his food supply in the forest, then migrates to our green belts and
ravages our crops. The sooner he is exterminated, the better. It's a question of simian survival.
Dr. Zaius: Have you forgotten your scripture, the thirteenth scroll? "And Proteus brought the upright beast into the garden and chained him to a tree and the children did make sport of him."
Dr. Zira: But what about your theory? The existence of someone like Taylor might prove it.
Cornelius: Zira, do you want to get my head chopped off?
Dr. Zira: Oh, don't be foolish. If it's true, they'll have to accept it.
Cornelius: [chuckles] No, they won't.
General Thade: Everything in the human culture takes place below the waist!
