This iconic clip originates from the 2016 animated film 'Batman: The Killing Joke,' featuring the legendary voice talents of Kevin Conroy as Batman and Mark Hamill as the Joker. The scene takes place at the very end of the movie after Batman apprehends the Joker, who proceeds to tell a joke about two inmates escaping a lunatic asylum. In a rare moment of shared humanity, Batman realizes the dark irony of their endless cycle and joins his nemesis in a fit of uncontrollable, rain-soaked laughter. Culturally, this meme represents the 'bonding over trauma' or 'finding humor in chaos' trope that resonates with internet users. It is frequently used to show two unlikely friends or enemies laughing at a situation that is actually quite dire or self-destructive. Popular captions often include: 'Me and the homie after making the worst decision of our lives,' 'When you're both failing the class but the joke was funny,' or 'Realizing we are both equally mentally unstable.'
