Russian scientists invoked unique device which teleports the pain of the woman in childbirth to the child's father. They decided to test the device, connect it to the woman in childbirth, turn it on 50% of power. They calls her husband:

"Do you feel something?"
"I'm feeling nothing! I'm watching the football!", answers the husband and hangs up.

The scientists turns the device on 75% of its power and calls again:
"Sorry, do you feel something?"

"I'm feeling nothing! I'm watching the football! Don't distract me!"

Scientists are in utter confusion. They turn the device on 100% of power. The woman feels nothing. They calls her husband:

"But now do you feel something?"

"Fcuking bastards you are! My team loses. The neighbour screams like crazy! And the phone rings every minute!"
