A psychiatrist said to his patient, "Mr. Patient, I understand that you have a problem. Your problem is that you always contradict whatever other people say or do, right?" And Mr. Patient said, "No, that's not right." So the psychiatrist said,"OK! Then I must be mistaken, eh?" And the patient replied,"No! No! You're not!" And the psychiatrist said, "Oh, oh, oh,I got it. I got it. You're contradicting everything I say." And the patient said, "No, you're being ridiculous! You're crazy!"So the psychiatrist said, "I see, I see. Then you're perfectly sane, right? You're not crazy, right?" And the patient said, "No. No. I'm crazy as a loon." Then the psychiatrist said, "Oh, yeah, now we're making some progress here!"
一位精神科医生问病人：「先生，我知道你有个毛病，就是不论别人说什么或做什么，你都一概否定，对吗？」病人回答：「不对，不对。」医生说：「好，那一定是我弄错了，是吗？」病人回答：「不，不，你没有错！」医生又说：「噢，我明白了，你就是一直否定我所说的话。」病人说：「不对，你这个人真可笑！你疯了！」医生就说：「我懂了，你神智完全正常，没有疯，对吗？」病人回答：「不对，不对，我是神智不清的疯子。」这时医生说：「很好，我们现在总算有点进展了！」
