One day at first school everyone's rubbers/pencil sharpeners went missing, nobody confessed to it, and during the final playtime of the day they were all left on my desk. I had no choice but to say it was me. I still have no idea who was responsible.
Do you have any stories as terrifying/mind bending as this? If so this is the place to post them, who knows, with the combined brain power of DiS maybe we could even crack a few of these cases.

By the way, no jokes about rubbers at first school.
