Teens have a knack for coming up with clever ways to rage against the system.
When I was in high school, the most notorious urban legend whispered about in hallways and at parties went like this: A teacher told his class that they were allowed to put "anything" on a notecard to assist them during a science test. Supposedly, one of his students arrived on test day with a grown adult at his side — a college chemistry major, who proceeded to stand on the notecard and give him answers. The teacher was apparently so impressed by the student's cunning that he gave him a high score, then canceled class for the rest of the week because he was in such a good mood.
Of course, I didn't know anyone who'd ever actually try such a thing. Why ruin a good story with reality — that pulling this kind of trick would probably earn you detention?
