Was a teacher in a 9th grade class. My students pranked me like a master. I bowed to their greatness. Looked out at the class that I'd get each and every one of them. I never brought it up again. They were on the edges of their seats whenever they saw me. For four years this went on. On the day of their graduation they asked me why I didn't prank them. My response was I pulled the greatest prank I could think of. You spent fours looking for me to get you. Four years looking over your shoulders. Best prank ever. They agreed. Best innocent revenge story out there.

Someone once told me they genuinely believe the earth is flat and argued for an hour like it was common sense.
