Haha, that was pretty funny. I had a history teacher that never really checked chapter reviews. He would always just look at how much you wrote. One time I decided to test my theory, and I wrote something to the effect of
"I don't really know the answer, but I'll just keep rambling on so it looks like I wrote a detailed answer.Hopefully, it'll fool you and my theory will be proven correct. Then I will rejoice and make fun of you with all of my friends."
It worked and I did as promised, but then I got too confident and tried it again, needless to say, my plan was foiled. Only spent an hour in detention though, was worth it.
