A married couple went to the hospital to have their baby delivered. Upon arrival the doctor said that he had invented a machine that would transfer a portion of the labour 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 at 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 bump the machine up a notch. The doctor then adjusted the machine to 20%. The doctor checked the husband's blood pressure and pulse and was amazed at how well he was doing. At 50% the husband was still holding up fine, since this was obviously helping out his wife he encouraged the doctor to transfer all of the pain. The wife delivered a healthy baby with virtually no pain. She and her husband were absolutely thrilled. Everything was great until they got home and found the postman dead on their porch.
