A woman goes into labor with her child. The doctor says that they have invented a new device to transfer the pain of childbirth to the father. He asks if it is ok to use the new device. The couple agrees, and so he turns the pain to the father to 10%. The man feels nothing.
They then bump it up to 20%. He still feels nothing, then his friend calls and he is groaning. He said he was having cramps, so the husband tells the doctor, "Doc, turn it up to 40%!" So he does, and his friend throws up, so he said, "Doc, turn it up to 100%!" and his friend dies.
