A married couple went to the hospital 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 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.  But
as the labour progressed, the husband felt fine and 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 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 milkman was lying dead on the porch.
