A married couple went to the hospital to have their baby delivered. Upon their arrival, the doctor said that the hospital was testing an amazing new high-tech 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. Both said they were 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.  But, 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 then 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 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, and the husband had experienced none. She and the husband were ecstatic.

When they got home, they found the UPS man dead on the porch. ??
