Excellent repartee by Tenshin Okakura, when an young American made fun of him and his group walking about in traditional Japanese outfit in 1903 Boston, as recounted in the Japanese wikipedia entry of Okakura:
Young man: "What sort of nese are you people? Are you Chinese, or Japanese, or Javanese?"
Okakura: "We are Japanese gentlemen. But what kind of key are you? Are you a Yankee, or a donkey, or a monkey?"
Okakura was a famous art critic and philosopher who was instrumental in preserving pre-Meiji Japanese arts that were being thrown away at a furious pace after the Meiji Restoration, but I just learned that he also wrote a book in English on tea, titled "The Book of Tea". The book was first published in 1906, and it is still sold today.
