Fantastic Fablesby Ambrose Bierce
THE Dog, as created, had a rigid tail, but after some centuries of a cheerless existence, unappreciated by Man, who made him work for his living, he implored the Creator to endow him with a wag. This being done he was able to dissemble his resentment with a sign of affection, and the earth was his and the fulness thereof. Observing this, the Politician (an animal created later) petitioned that a wag might be given him too. As he was incaudate it was conferred upon his chin, which he now wags with great profit and gratification except when he is at his meals.
