The 'Say the Line, Bart!' meme originates from the 1994 'The Simpsons' episode titled 'Bart Gets Famous.' In the scene, Bart has become an overnight sensation for his catchphrase 'I didn't do it,' but he quickly grows depressed by the repetitive nature of his fame. The meme features a dejected Bart surrounded by classmates who are eagerly waiting for him to speak. On the internet, this template is used to mock people or brands that are expected to deliver a predictable, cliché, or repetitive statement that the audience already anticipates.
