The My leg line is a long-running gag in SpongeBob SquarePants, where a background fish repeatedly suffers an accident and shouts the same pained cry. Because the joke recurs in different episodes, viewers began to recognise the fish by that single line alone, and clips of the shout spread widely as a reaction sound in memes, gaming videos and short-form edits. Its appeal has lasted because the cry is short, clear and instantly comic, turning almost any minor injury or failure into an exaggerated cartoon moment.
