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.
