Someone holds the world record for the bloodiest fart. No one cares because it’s gross and humiliating. Sadly, someone’s greatness will go unrecognized for posterity’s sake.
Batman asks Superman, “Do you bleed?” This is a subtle nod to the fact that Kryptonian males MENstruate. This line of inquiry is simply Batman trying to get more information on Kryptonian physiology because he is unsure if Superman has gone through “the change.”
Batman did NOT ask Wonder Woman because he didn’t want to get kicked in the pee pee.
