The "Joker Hospital Explosion" meme is one of our favorites. It features a still from The Dark Knight movie, where the Joker blows up a hospital, with the caption "I'm a man of my word." This meme is typically used to express satisfaction or fulfillment of a promise, often in a humorous or sarcastic way. We find it funny because it's a dramatic and memorable moment from the movie that's been turned into a humorous meme. You can use this meme to react to someone who has fulfilled a promise, or to sarcastically express your own satisfaction with something.
