Mermaid Man and Barnacle Boy are the retired superhero duo from SpongeBob SquarePants, famous in Bikini Bottom for their endless bickering and for being past their prime. Their grumpy exchanges became a favourite source of reaction clips because the contrast between heroic status and everyday old-age squabbles is easy to reuse. As short soundboard clips spread on social media, lines like this one travelled far beyond the original episode, kept alive by fans who use them to deny blame with comic stubbornness.
