'$8,000 for a male brain, and $500 for a female brain'.
A group of relatives were at the hospital, visiting a very sick member of the family.
The doctor appeared, looking grave, and told them the bad news:
'Your relative is seriously ill, and his only hope is to have an experimental operation - a full brain transplant. This is a very risky and costly operation, but your insurance will cover everything but the cost of a replacement brain'.
After a period of silence, one of the family members asked, 'Well, how much will it cost for a brain ?'.
'$8,000 for a male brain, and $500 for a female brain', the doctor replied.
'Why does a man's brain cost so much more ?'.
The doctor smiled. 'Well', he said. 'Female brains are priced at a discount because they have actually been used'.
