When I was in primary school, maybe 7 or 8, I was in a school assembly and our principal was making a speech. He was just joking around with us when he said one of the secretaries at the school was a ninja and that we had to keep it a secret. I really, truly believed the woman was a ninja and that if we told anyone, we'd get detention.
