How did you start the flood? 你是怎么引起洪水的？
A doctor vacationing on the Riviera met a lawyer friend and asked him what he was doing there. The lawyer replied, " I'm here because my house burned down, and the insurance company paid for everything. What are you doing here?" "That's quite a coincidence," said the doctor "I'm here because my house were destroyed by a flood, and my insurance company also paid for everything." The lawyer looked puzzled. "Gee," he asked, "how did you start the flood?"
医生在里维埃拉度假时遇到他的一位律师朋友，医生问他怎么会到这里来。律师回答：“我到这里是因为我的房子被火烧了，保险公司赔偿了我所有的损失。” “真巧，”医生说，“我是因为房子被洪水冲垮了，保险公司也赔偿了我所有的损失。”律师看起来有些困惑，他问“哎呀！你是怎么引起洪水的？”
