PHILOSOPHY MASTER: And the vowel I, by bringing the jaws still nearer each other and stretching the two corners of the mouth towards the ears: A, E, I.
MONSIEUR JOURDAIN: A, E, I. I. I. I. That's true. Long live science!
PHILOSOPHY MASTER: The vowel O is formed by opening the jaws and drawing together the two corners of the lips, upper and lower: O.
MONSIEUR JOURDAIN: O, O. There's nothing truer. A, E, I, O,I, O... That's admirable! I, O, I, O.
PHILOSOPHY MASTER: The opening of the mouth happens to make a little circle which represents an O.
MONSIEUR JOURDAIN: O, O, O. You are right! O. Ah! What a fine thing it is to know something!
PHILOSOPHY MASTER: The vowel U is formed by bringing the teeth nearly together without completely joining them, and thrusting the two lips outward, also bringing them nearly together without completely joining them: U.
MONSIEUR JOURDAIN: U, U. There's nothing truer. U.
PHILOSOPHY MASTER: Your two lips thrust out as if you were making a face, whence it results that if you want to make a face at someone and mock him, you have only to say to him "U."
MONSIEUR JOURDAIN: U, U. That's true. Ah! Why didn't I study sooner in order to know all that!
