The meme featuring Casey Affleck trying to shoot himself arises from a poignant yet intense scene in the film "Manchester by the Sea." In this 2016 drama, Affleck's character, Lee Chandler, is engulfed in grief and despair, leading to a moment where he attempts to take his own life by grabbing a police officer's gun. This scene, laden with emotional weight, has been transformed by the internet into a darkly comedic meme. It's the stark contrast between the gravity of the scene and the triviality of the situations it's applied to that gives this meme its punch, making it a staple in the world of online humor.
