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."
