In the Hospital the relatives gathered in the waiting room, where
their family member lay gravely ill. Finally, the doctor came in
looking tired and somber.

"I'm afraid I am the bearer of bad news," he said as he surveyed
the worried faces, "The only hope left for your loved one at this
time is a brain transplant. It's an experimental procedure,
semi-risky, and you will have to pay for the brain yourselves."
The family members sat silent as they absorbed the news. After a
length of time, someone asked, "Well, how much does a brain
cost?" The Doctor quickly responded, "$5000 for a male brain, and
$200 for a female brain."

The moment turned awkward. Men in the room tried not to smile,
avoiding eye contact with the women, but some actually smirked. A man, unable to control his curiosity, blurted out the question
everyone wanted to ask, "Why is the male brain so much more?"

The doctor smiled at the childish innocence and then to the
entire group said, "It's just standard pricing procedure. We have
to mark down the price of the female brains, because they've been
used."
