This Saturday at Comic-Con, our own Papa Lama (Dr. Travis Langley) and his fellow psychologist Dr. Robin Rosenberg (editor, The Psychology of Superheroes) will delve into the psyche of Batman’s arch-nemesis, the Joker, with the help of an illustrious panel of industry professionals, starting with the man who created the Joker back in 1940. Recently Travis and Robin enjoyed speaking with Jerry for the better part of an hour.
