脑移植 A Brain Transplant
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."
