Good News & Bad News

A man has a headache and goes to see the doctor.  The doctor says "I
have bad news and good news.  The bad new is that you have a brain
tumor.  The good news is that we can do a brain transplant, and we
have just admitted a couple who was in a car accident.  We can get you
one of their brains.

The male brain will cost your insurance company $100,000, and the
female brain will cost $30,000."  The man says "I hate to be rude, but
why does the male brain cost so much more than the female brain?"
The doctor replies "Because the male brain has never been used."
