2019 marks the 80th anniversary of Batman's debut in Detective Comics #27 and has seen the Joker motion picture break box office records. The grim, brooding hero who looks like a monster found his arch-nemesis in the bright, laughing monster who looks like a clown. What is it about these two characters that has kept them locked in relentless conflict through literally hundreds of stories? And why do people (not just Harley Quinn) love that killer clown? Join Dr. Travis Langley (Batman and Psychology; The Joker Psychology) and Athena Finger (Batman and Bill) as they strive to answer the killing joke.
