A married couple went to the hospital together to have their baby delivered. Upon their arrival, the doctor said he had invented a machine that could transfer a portion of the mother’s labour pain to the father. He asked if they were willing to try it out, and they both agreed enthusiastically. The doctor set the knob 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, 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, so the doctor upped the percentage to 50% and finally 100%, since the wife was obviously benefitting from the transfer. 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 their porch.
