In my Senior year of high school, I was taking a quiz in my Calculus class that I hadn’t studied for, and I knew I was going to fail. So when my teacher wasn’t looking, I folded the quiz paper up as small as I could, and stuck it into my shoe. I walked out of class pretending that I had turned it in. The next day, my teacher came up to me and said he had “misplaced” my quiz. He gave me a week to retake the quiz, and I got 100% on it.
