Home Alone is the 1990 Christmas comedy film about Kevin McCallister defending his house from two burglars, with a festive orchestral score by John Williams. This flute and kazoo version strips that score down to two toy-like instruments, which is why editors adopted it as a meme song for sneaky, childlike scheming. It circulated online in short video edits and soundboard collections alongside other joke covers, and it remains popular every holiday season because the melody is instantly recognisable even when played badly on purpose.
