Jim and Mary were both patients in a Mental Hospital. One day while they were walking by the hospital swimming pool, Jim suddenly jumped into the deep end. He sank to the bottom. Mary promptly jumped in to save him. She swam to the bottom and pulled Jim out. When the medical director became aware of Mary's heroic act he immediately reviewed her file and called her into his office. "Mary, I have good news and bad news. The good news is you're being discharged because since you were able to jump in and save the life of another patient, I think you've regained your senses. The bad news is Jim, the patient you saved, hung himself with his bathrobe belt in the bathroom，he's dead." Mary replied, "He didn't hang himself, I hung him up to dry." Jim和Mary都是精神病院里的病人。一天，他们沿着医院的游泳池散步，Jim突然跳入泳池的深水区，他沉到了底部。Mary立刻跳下去救他，她潜到水底，把Jim拉了上来。 当院长听闻了Mary的英勇行为后，他立刻翻看了她的病历档案,把她叫进了自己的办公室. “Mary，我有一个好消息和一个坏消息要告诉你。好消息是你能跳入水中救其他病人，这说明你的意识已经恢复了，你可以出院了。坏消息就是，Jim，你救的那个病人，他还是用自己的浴袍带子在浴室上吊自杀了。” Mary说：“他没有自杀，是我把他吊起来好让他晾干。”
