Giving birth.

[Deus Ex Machina.]

Once, there was a couple who went to this hospital, with the mother ready to give birth.

The doctor wanted to try his new invention on the couple. He told them his new invention will relocate certain percentages of the pain from the mother to the father. The couple agreed to try it out.

Afraid to knock out the father, the doctor first set the transfer rate at 90-10. As the mother struggled, the father said he doesn't feel anything. The doctors upped the transfer to 80-20. Still no response from the father.

Amazed, the doctor kept raising the transfer rate. 70-30, 60-40, 50-50. Soon, the father was getting most of the burden, but he still claimed he felt nothing.

Finally, the rate of transfer was maxed out at 0-100. The mother then delivered the birth with zero pain while the father was ecstatic. They both walked out of the hospital, feeling very happy.

They went home to find the milk-man dead by their front yard.
