This classic Christmas comedy was a major source of festive memes before memes were even a thing! All Ralphie (Peter Billingsley) wants for Christmas is a BB gun, but he's having a pretty hard time convincing the adults in his life that it's an appropriate present. Along the way, he and his family have several other, loosely connected adventures. It's best known as a movie that gets traditionally marathoned on TV on Christmas Day, but it's actually based on In God We Trust: All Others Pay Cash, a semi-fictional book based on a series of anecdotes by humorist Jean Shepherd.
