"Well," said the animal, "I know many vegetables that are very clear on that point. Which is why it was eventually decided to cut through the whole tangled problem and breed an animal that actually wanted to be eaten and was capable of saying so clearly and distinctly. And here I am." …….
"A very wise choice, sir, if I may say so. Very good," it said, "I'll just nip off and shoot myself."
(D.Adams, The restaurant at the end of the Universe)
Douglas Adams the writer of the Hitchhikers Guide to Galaxy, in his science fiction book the “The Restaurant at the End of the Universe”, has a wonderfully surreal scene. Guests at the restaurant are asked to choose which parts from a live animal they wish to eat, while watching the end of the Universe. The animal voluntarily wants to be eaten.
