A married couple went to the hospital together to have their first
baby delivered. Upon their arrival, the doctor said that the hospital
had invented this machine that would transfer a portion of the mother's
pain through to the father. He asked if they would be willing to try it
out. They said they would both be very much in favour of it.
The doctor then set the dial to give the husband just 10% of the
pain his wife would be feeling, explaining that 10% of this pain would
probably be more pain than the father had ever experienced in his 
life before.  Soon after the woman began to go into labour. As this
progressed the man felt fine and his wife was in agony so he asked
the doctor to put the machine up to 20% of her pain. After 10 minutes
the doctor checked the man's blood pressure and pulse and was amazed a
how well he appeared to be doing. Because of this the doctor decided to
try for 50%.
The man still felt fine and because this was obviously helping his
wife out he asked the doctor to transfer ALL the pain to him.
Eventually, his wife delivered a perfectly healthy baby with 
virtually no pain. The doctor was amazed and told the man that 
the pain that he had endured was enough to kill any normal man. 
Obviously the man and his wife were ecstatic about their newly 
born child and the virtually pain free way he was delivered. 
This was until they got home to find the milk man  lying
dead on their porch.....
