LOL. But I don't think anyone should be forced to be a father if he doesn't want to be. Let's just not delude ourselves that signing a piece of paper which means fetus gets born but you don't have to pay for it has very different emotional impact to ensuring it never will.
I am sure that very many women considering an abortion would go for the 'sign the piece of paper so the problem goes away for you without killing the fetus. Someone else will go through the pain & discomfort of pregnancy & 18 years of hard work' if it were available.
