A client of a hospital where they made brain
transplantations asked
about the prices.

The doctor said,
“Well, this Ph.D. brain costs $10,000. This brain
belonged to a NASA
top scientist and costs $15,000. Here we have a
policeman’s brain as
well. It costs $50,000.”

The client asked, “What? How’s that
possible?”

The doctor replied, “You see, it’s totally unused.”
