No one has both given birth and been kicked in the nuts really hard, so let’s settle this finally by getting some steel toed boots, kicking a guy in the nuts really really really really fucking hard, then smashing him in the head with a sledgehammer really hard, we’ll have to do it multiple times till we get the exact amount of pain he has when he was kicked in the nuts, then we hit a mother with the sledgehammer with the same amount of force & she’ll tell us if it hurt more or less than giving birth
If one or more of the test subjects doesn’t make it, we’ll have to try again on a different test subject
