The 'You're Laughing' meme originates from a pivotal scene in the 2019 psychological thriller Joker, featuring Joaquin Phoenix as Arthur Fleck and Robert De Niro as the talk show host Murray Franklin. In the scene, Murray reprimands Arthur for his behavior, famously stating, 'You're laughing. Someone was killed today because of what you did, and you're laughing.' Internet users quickly adopted the format to highlight the absurdity of finding humor in tragic, mundane, or niche situations. It is frequently used as a reaction image to mock people who enjoy others' misfortunes or to ironically point out a dark sense of humor in digital discourse.
