As the human mating ritual seems to only involve chocolate milkshakes during the casual dating phase, I am inclined to say that this is the only truly civilized part of this particular Homo sapien custom.
Dr. Zira, I must caution you. Experimental brain surgery on these creatures is one thing, and I'm all in favor of it. But to suggest that we can learn anything about the simian nature from a study of man is sheer nonsense. Man is a menace, a walking pestilence. 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.
