Why do men exist? To provide genetic material, of course! But if that's all they're doing, why do they make up 50% of the population? Wouldn't we only need a couple of men around to fertilize eggs, before sending them back into their man caves? Don't worry, I'm talking about the animal world, because I know humans need men to help care for their offspring, install lighting fixtures, and make tough financial decisions.
