The song itself is a long-familiar folk tune that many people first learn as a children's song, which is part of why this version feels so strange. In this clip, the cheerful lyrics are delivered in the style associated with the LeEvil James meme, giving a warm, well-known melody an eerie, off-kilter edge. That contrast helped it spread through short-form edits, reaction clips and horror-themed memes, where creators use the familiar tune to set up comfort before subverting it. Its staying power comes from that instant recognition.
