The Angry Tom Reading Book meme originates from the 1951 Tom and Jerry animated short titled Jerry's Cousin. In the scene, Tom Cat is trying to enjoy a newspaper or book when he is repeatedly bothered by Jerry's incredibly powerful cousin. The meme captures Tom's look of intense, wide-eyed fury as he lowers the book to glare at the source of his annoyance. It became a viral sensation on platforms like Reddit and Twitter, typically used as a reaction to seeing something nonsensical, offensive, or confusing. It perfectly encapsulates the feeling of being interrupted or shocked by something ridiculous in the real world.
