Once a doctor invented a birthing pain share machine, where a spouse could share the joys and pains of birthing with their partner. So a couple walks in and was ready for labor and they agreed to try the device.
The doctor diverted 1 % and checked to see how the husband felt, he said he was okay. They proceeded with 5%, 10%, 25% and up to 50% and the husband was still feeling fine. They were proud parents of a beautiful baby and proceeded to head home.
When they got home, they found the mailman dead at their front door.
