The Brain Surgeon was about to perform a brain transplant.

"You have your choice of two brains," he told the patient, "For $1000 you can have the brain of a psychologist, or for $10,000 you can have the brain of a politician."

The patient was amazed at the huge difference in price. "Is the brain of a politician that much better?" he asked.

The Brain Surgeon replied, "No, it’s not better, just unused."
一个外科医生正要作一个脑移植手术。
　　“你可以从两个脑子中选一个给你。”医生告诉病人，“一个心理学家的大脑1000美元，一个政治家的大脑10000美元。
　　病人很惊讶二者之间这样大的差别，“政治家的大脑好一些吗？”他问。
　　医生说：“不是好一些，只是没有用过。”
