Batman: The Killing Joke - The episode's ending is similar to Batman: The Killing Joke, where the Joker, after failing to shoot Batman with a gun, tells Batman to beat the heck out of him after confessing what he had done to Barbara and Comissioner Gordon, but Batman denies, saying that he will help the Joker rehabilitate but the Joker said no, saying that it's far too late for that. But Joker tells Batman a joke that made him laugh, like where Francis tells Timmy and Ivan it's too late to be redeemed but asked them to dance with him because his parents are not here.
