“Four legs good, two legs bad.”

“Four legs good, two legs better! All Animals Are Equal. But Some Animals Are More Equal Than Others.”

“Whatever goes upon two legs is an enemy. Whatever goes upon four legs, or has wings, is a friend.”

“...out from the door of the farmhouse came a long file of pigs, all walking on their hind legs...out came Napoleon himself, majestically upright, casting haughty glances from side to side, and with his dogs gambolling round him. He carried a whip in his trotter. There was a deadly silence. Amazed, terrified, huddling together, the animals watched the long line of pigs march slowly round the yard. It was as though the world had turned upside-down. Then there came a moment when the first shock had worn off and when, in spite of everything-in spite of their terror of the dogs, and of the habit, developed through long years, of never complaining, never criticising, no matter what happened-they might have uttered some word of protest. But just at that moment, as though at a signal, all the sheep burst out into a tremendous bleating of- "Four legs good, two legs better! Four legs good, two legs better! Four legs good, two legs better!" It went on for five minutes without stopping. And by the time the sheep had quieted down, the chance to utter any protest had passed, for the pigs had marched back into the farmhouse.”
