The joke works because the Titanic theme is one of the most recognisable melodies in film, instantly signalling romance and tragedy even when it is played badly. Short, deliberately rough covers of famous tunes have long circulated on soundboards and in meme edits, where a familiar song is stripped of its grandeur for comic effect. This flute version follows that pattern, keeping the tune just clear enough to recognise while the shaky performance does the comedy, which is why creators keep reaching for it when a scene needs to feel both dramatic and ridiculous.
