雅舍小品txt下载:帮我看看这个英语笑话讲的是什么？

摆脱帮我翻译一下这个笑话好吗？非常感谢
A married couple went to the hospital to have their baby delivered. Upon

their arrival, the doctor said that the hospital was testing an amazing

new high-tech machine that would transfer a portion of the mother's

labor pain to the baby's father. The machine was remarkable as it

required no attachments to the dad but would transfer the pain.

He asked if they were willing to try it out. Both said they were very

much in favor of it. The doctor set the pain transfer to 10 per cent 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 and asked the doctor

to go ahead and kick it up a notch. The doctor then adjusted the machine

to 20 per cent pain transfer.

he husband was still feeling fine.! The doctor then checked the husband's blood

pressure and was amazed at how well he was doing.

At this point they decided to try for 50 per cent. The husband continued

to feel quite well.

Since the pain transfer was obviously helping 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, and the

husband had experienced none. She and her husband were

ecstatic..................

When they got home, the postman was dead on the porch
