A man's brain replacement

A man's brain replacement

A man was at his doctor's office planning his brain replacement surgery. He was
told that a male brain replacement would cost him approximately $50,000. He
also was told that a female replacement would cost only $3,000. He was curious
about the difference of the cost and was told that the male brain would not have
been used very much but, the female brain would be used and very probably
completely used.
