The 'That's It? That's the Lost Episode?' meme is taken from the SpongeBob SquarePants special 'The Sponge Who Could Fly' (2003). In the episode's live-action segment, Patchy the Pirate is overcome with rage and disappointment when the highly anticipated 'lost' episode turns out to be nothing more than a cheap loop of SpongeBob walking. Patchy's reaction—screaming the line before having a breakdown—perfectly captures the feeling of being let down by massive hype. It has since become a go-to template for the internet to criticize lackluster movie endings, disappointing game updates, or any situation where the reality fails to meet the expectations.
