英語笑話:Pain Transference 疼痛轉移

A married couple went to the hospital together 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 labor 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 to 10 percent for starters, explaining that even 10 percent was probably more pain than the father had ever experienced before.

But as the labor 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 percent pain transfer.
The husband was still feeling fine. The doctor checked the husband's blood pressure and pulse and was amazed at how well he was doing. At this, they decided to try for 50 percent.
The husband continued to feel quite well. Since it was obviously helping out his wife considerably, he 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 mailman was dead on their porch.簡介：一對夫婦去醫院，女的面臨生產，醫生告訴他們他發明了一個能將產婦生產過程中的疼痛轉移到孩子父親身上的儀器，夫婦倆高興的想試一下，可是在生產過程中，醫生把旋轉鈕調到 10% 疼痛轉移， 20%， 50%， 丈夫都沒感到任何不適，最後乾脆調到了 100%，可是丈夫還是一點都不疼，同樣的，妻子感覺也很好。醫生覺得非常驚訝。當夫婦倆興高采烈的回到家後，才發現常給他們送信的郵遞員死在他們家門口了。
