Oh Don Piano comes from the Oh Long Johnson talking cat video that spread online in the late 2000s, where viewers transcribed the cat's meows as a string of slurred phrases. The misheard lines became the joke, repeated in remixes, captions and parodies, and the cat was later referenced in animated television. Because different listeners hear different words, the clip stayed shareable as a guessing game as much as a sound effect. It remains a staple meme audio for pets, dubbed animals and any scene built around incomprehensible muttering.
