参考：

Duncan was a famous woman dancer. She was very beautiful and successful in dancing, but she wasn’t so bright.

Bernard Shaw was a world-famous writer and humorist, but he was an ordinary-looking man.

Duncan admired Bernard Shaw´s genius for literature and wrote to him for love. In her letter she said, "Dear Mr. Bernard Shaw, I love you very much. You have a wise brain and I have a pretty body. If we get married, I´m sure we will have a baby with your brain and my body."

Having received Duncan’s letter, Bernard Shaw gave her a humorous answer. It said, "Dear Miss Duncan, glad to receive your letter, but I dare not accept your love. I love you even more, but I´m sorry I can´t marry you because I´m afraid that if we get married perhaps we will have a baby with your brain and my body."
