Transfer Pain

Mr and Mrs Duyankpan were having their baby and were invited to make use of a new machine that would transfer a portion of the mother's labour pains to the baby's biological father wherever he may be. Both were happy to try it.
The pain transfer was set to 10 percent but Mr. Duyanpkan felt nothing so the doctor increased it to 20 percent. He said he still felt fine and his blood pressure was normal. He invited the doctor to kick it up to 50 percent. Still no reaction. The doctor was amazed and slowly transferred all the pain until Mrs delivered a healthy baby with virtually no pain. She and Mr Duyankpan and the doctor were ecstatic. When they got home, they found their gateman lying dead at the gate. Ouch!
