In the hospital, the relatives gathered in the waiting room, where a family member lay gravely ill. Finally, the doctor came in looking tired and sombre. "I'm afraid I'm 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, quite risky, and you'll have to pay for the brain yourselves." The family members sat silent as they absorbed the news. At length, someone asked, "Well, how much does a brain cost?" The doctor quickly responded, "A female brain goes for $20,000. A male brain costs $50,000." The moment turned awkward. Men in the room tried not to smile, avoiding eye contact with the women, but some actually smirked. A girl, unable to control her curiosity, blurted out the question everyone wanted to ask, "Why does the male brain cost so much more?" The doctor smiled at her childish innocence and then said to the entire group, "It's a standard pricing procedure. We mark the female brains down because they're used."
