A married couple went to the hospital together 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
father.

He asked if they were willing to try it out. They were both very much in
favor of it.

The doctor set the knob to 10% for starters, explaining that even 10
percent was probably more pain than the father had ever experienced before.
But as the labor progressed, the husband felt fine, so he asked the doctor
to go ahead and bump 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 pulse and was amazed at
how well he was doing. At  this, they decided to try for 50%.

The husband continued to feel quite well.

Since it was obviously helping out his wife considerably, he encouraged the
doctor to transfer ALL the pain to him. The wife delievered a healthy baby
with virtually no pain.

She and her husband were ecstatic. When they got home, the mailman was dead
on their porch.
