The Brain Surgeon was about to do a brain transplant. "There are two brains which wait for your choice ," he told his patient, "if you pay $2000 you can have the brain of a psychologist, or for $20,000 you can have the brain of a politician." 　　The patient was surprized at the big 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."
