Around here it's mostly Na-na-na-na-na-na, I think, although I have heard the one ending in boo-boo too. "Here" being southern Ontario, Canada. It's got to be the most annoying tune of all time.

Remember the old Batman TV theme?...Na-na..na-na..na-na..na-na..na-na...na-na...na-na..na-na...Batman!...Batman!...Batman...Na-na-na...etc. It's a different tune, but equally relentless, and it just goes on and on endlessly. I used to hear kids doing that one a lot.
