Old MacDonald Had a Farm is a traditional children's song about a farmer and his animals, known for generations through nursery books and singalongs. Comedian and musician Bill Wurtz, known online for his deadpan songs and history videos, gives the rhyme a brief absurdist twist in this version, where the expected animal sounds are replaced by an explosion. Shared as a short soundboard clip, the farm exploded version spread through meme edits and reaction videos, where creators reuse the familiar opening as a setup for sudden failure, destruction or an unexpected ending.
