In this episode, Curt and Kevin return to Gotham City and put on their Dark Knight Detective caps to sift through labored puns, fun-house felonies and other offenses as they consider the strange case of Alan Moore and Brian Bolland's highly acclaimed 1998 DC Comics graphic novel, Batman: The Killing Joke! But first, they take a quick detour to the black-and-white days of 1951 for a very different look at the origin of Killing Joke antagonist the Joker! Listen to our heroes match wits with the Caped Crusader and his Boy Wonder as they try to crack the conundrum of The Man Behind the Red Hood! Will our dynamic duo sentence the Joker to rot behind the imposing gates of Arkham Asylum? Or will the Clown Prince of Crime find himself laughing all the way to that big score known as ... The Comics Canon?
