Did you guys sing songs about killing Barney in school, too? Is this phenomena passed down knowledge or spawns naturally in kids?

I hate you, you hate me, let's get together and kill Barney ♪

Recently I found out that pretty much every kid had a version of this song in their school—from the US, to the UK, to the Caribbean. Is this remix passed down or do kids think of it themselves every generation? I'm genuinely curious.
