Quote: The monkey is the only animal, except man, that practices this science; hence he is our brother; there is a bond of sympathy and relationship between us. Give this ingenious animal an audience of the proper kind, and he will straightway put aside his other affairs and take a whet; and you will see by the contortions and his ecstatic expression that he takes an intelligent and human interest in his performance.?
-Mark Twain, from his speech, Some Thoughts on the Science of Onanism, 1879.
