Via Charles Shields’s And So It Goes: Kurt Vonnegut: A Life comes this great prank idea from Kurt Vonnegut:
He came up with a prank to ridicule his classmates’ angst over grades. Taking a seat for a final exam at midyear in a class he wasn’t registered for, he waited until everyone was deep into the test. Then with a groan of disgust, he ripped the exam to shreds, stalked up the aisle, and tossed the pieces of paper into the astonished instructor’s face, storming out the classroom door. It started a fad among the student body that lasted a few semesters.
It’s getting to be final exam time, and though teacherly propriety prevents me from endorsing this prank outright, I do sort of think it would be cool if it caught on.

It’s something I think many students fantasize about doing someday!
