Pygmalion.

The complete text of George Bernard Shaw's play 'Pygmalion', perhaps better known as the basis for 'My Fair Lady', is available at wikipedia.org. I've always liked this story, mainly for its object lessons in the importance of language to the structure of society.

The original play contains a completely different ending, which alters the meaning of the entire story. This is not some flimsy love story, but rather a story about strength of character. If you read and appreciate this version, the watered down 'My Fair Lady' will disgust you to no end.
