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 labour pain to the baby's father.
He asked if they were willing to try it out. They were both very
much
in favour 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 labour 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 home, the mailman was dead on the porch.
