Eh….okay but if you u didn’t know that the joker fell into vat of acid when dressed as the red hood and bleached his entire body giving him white skin and green hair and that bleach causes cell death and deterioration on sensitive skin and the penis im pretty sure is the softest skin of all would seriously mess that shit up but you can’t exactly put dick surgery in a comic book so until proven otherwise based on The facts we know about the chemicals in the vat he fell in and how long he was in it plus what those chemicals do to the body we can conclude that. JOKERS DICK DON’T WORK and is probably just a giant infection
