Labor pains!!

A married couple went to have their baby delivered.
Upon their arrival, the doctor said he had invented a new machine that
would transfer a portion of the mother's labor pain to the baby's
father.
He asked if they were willing to try it out.
They were both very much in favor of it.

The doctor set the pain transfer to 10% for starters, explaining that
even
10% was probably more pain than the father had
ever experienced before. However as the labor progressed, the husband
felt fine and asked the doctor to go ahead and kick it up a notch. The
doctor then adjusted the machine to 20% pain transfer. The husband was
still feeling fine.
The doctor checked the husband's blood pressure and was amazed at how
well
he was doing. At this point, they decided to
try for 50%. The husband continued to feel quite well. Since the pain
transfer was obviously helping out the wife considerably, the
husband encouraged the doctor to transfer ALL the pain to him. The
wife
delivered a healthy baby with virtually no pain. She and her husband
were
ecstatic.

When they got in the car to get home, they found the driver dead in the
car.
