A client of a hospital where they made brain transplantation’s 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 blonde’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.”
