I'm trying to figure out how that second point worked. Is it that you were whistling too often and it would have been a problem even if you were going with, say, the Andy Griffith theme, or did you both whistle so well and have school administrators so educated that they identified that you were whistling Nazi propaganda?

It's not that characteristic a tune.

It was the national anthem of Nazi Germany. If you have a even a passing interest in WWII, which I hope at least some teachers would, it should be familiar.
