A large difference

A man went to the doctor's. The doctor came in and said,"Well, I've got some good news and some bad news. The badnews is that you have an inoperable brain tumor. The goodnews is our hospital has just been certified to do braintransplants and there has been an accident right out frontand a young couple was killed and you can have whicheverbrain you'd like. The man's brain costs $100,000.00 and thewoman's brain costs "30,000.00." The patient could not help but ask, "Why such a largedifference between the male and the female brain?" The doctor replied, "The female brain is used."
