The brain surgeon was about to perform a brain transplant.
"You have the choice of two brains," he told the patient, "for $1000 you can have the brain of a Astronaut, or for $10,000 you can have the brain of a Politician."
The patient was so much amazed at the huge difference in the prices, "Is the brain of a politician that much better?"
he asked.
The brain surgeon replied, "No, it's not better, just unused."
