A couple rushed into the hospital because the wife was going into labor.

As they hurried down the hall, a doctor stopped them and said, “I’ve invented a machine that can split the pain of childbirth between the mother and the father.”

They agreed and were taken into a room where they were hooked up to the machine.

The doctor started it at 20% transferred to the father.

The wife said, “Oh, that’s actually better.”

The husband said, “I don’t feel anything.”

The doctor increased it to 50%.

The wife smiled and said, “That doesn’t hurt nearly as much now.”

The husband replied, “Still nothing.”

Encouraged, the doctor turned it all the way up to 100%.

The husband still felt nothing, and the wife was thrilled because she felt no pain at all.

The baby was born.

Later, when the couple arrived home, they found the postman lying on the doorstep, groaning in pain.
