Memetic Mutation: "Batman, you killed the Duplicant Bullock!" "He was a Duplicant?" Explanation The scene in which Batman destroys the robot Bullock, due to him and Barbara not having any proof that "Bullock's" not human and isn't just acting more of an asshole than usual before the Robotic Reveal, often ends up drawing comparisons to a certain scene from the "Treehouse of Horror III" episode of The Simpsons.
