Ah - the benefits of an international forum. One thing that resonates perfectly across all cultures is music. Within these borders, I've found two childhood songs that make my skin crawl every time i think of my childhood days singing these in classes.
First one is a great little tune with a patriotic message too:

Second is a nice little Deutsch (spelt 'Dutch' in North America) Canadian influence. Happy polka times:
What are your culturally relevant folk songs you reminds you of your childhood?
