Mr. Grumpy is the quintessential curmudgeon of the Mr. Men world—he hates everything happy, beautiful, and pleasant, especially Christmas. The book focuses entirely on his miserable, perpetually frown-faced existence. The story usually revolves around an attempt by the other Mr. Men to cheer him up, which Mr. Grumpy naturally resists with all his might. The humor comes from the sheer absurdity of his endless unhappiness and his attempts to shut the world out. Despite his best efforts to remain miserable, the narrative often ends with a tiny moment of reluctant joy or a humorous realization of the futility of his grumpiness.
