The line comes from 'Coconut,' Harry Nilsson's novelty song released in 1971, built around a woman telling her doctor she put the lime in the coconut and drank them both up. Its odd, repetitive call-and-response and island lilt made it a lasting earworm, revived by its appearance in Reservoir Dogs and countless commercials, covers and comedy bits. Online it lives on as a reaction clip: creators use the short phrase to mock circular logic, silly recipes or remedies that are secretly the problem. The 1971 record's charm keeps it funny decades later.
