Back in the bad old days, I had my ninth graders choose and re-write a fairy tale. One student asked if he could use a thermonuclear device somewhere in the story*. Before I could say anything, another student chimed in with: "Well, that gives new meaning to the name 'Cinderella', doesn't it?"
*Unless something was truly warped or disturbing, I tried not to censor content too much in student assignments. The school where I taught was a fairly conservative (but not insanely so) Christian school. One girl, who was in the full throes of teen rebellion, asked if she could do her term paper on Aleister Crowley. "Sure," I said.
Pause.
"You know who he was, right?" she asked.
"Self-styled 'most evil man on Earth' and a big influence on Led Zeppelin. Speaking of which, Dean's doing his term paper on them, so you may want to share some sources," I replied.
I think she was expecting to get in trouble. The final paper included a rather graphic retelling of an incident involving a goat. I honestly think this girl was hoping/expecting to get suspended or expelled. IIRC, I think I pointed out that she used improper formatting for an extended quotation.
