幽你一默：医生你确定我得的是肺炎吗

　　Patient: “Doctor, are you sure I’m suffering from pneumonia? I’ve heared once about a doctor treating someone with pneumonia and finally he died of typhus.” Doctor: “Don’t worry, it won’t happen to me. If I treat someone with pneumonia he will die of pneumonia.”

　　病人：“医生，你确定俺得的是肺炎吗？我曾经听说过一位医生按肺炎给一个病人治疗，结果那个病人因为斑疹伤寒而死了。”医生：“不要着急，这种情况在我这儿不会发生。如果我按肺炎给病人治疗，他一定会死于肺炎的。”
