Before I learned about the alcoholic drink, I thought the song "Brass Monkey" was about those kitschy toy monkeys that bang the cymbals together. Due to that, I really really liked the song and would go around singing it and pantomiming that I was banging cymbals together.
People probably thought I was retarded.
A childhood belief about songs

I'll never let you go...
I thought he was singing:
Another machine gun...
