“The Joker’s Last Laugh” arc is Lorenzo Semple Jr.’s last writing for “Batman”, a teleplay from a story written by crime novelist Peter Rabe. But that story originally featured Two-Face! (Read the treatment here. Thanks to High C for providing!) The Joker version contains at least one vestige of the Twofaceiness of the original story, and also shows Semple seeming to comment on the sitcom that the series had become. Other topics include: how we, too, were driven crazy by laugh tracks; the history of the Jokemobile; the Iggy Pop version of the Batman theme (NOTE: has a few f-bombs in it); and of course, your mail!
