Senior Skip Day and Pranks

Everyone did that their senior year of High School, right? Had an official skip day and/ or Senior prank? I'm guessing not so much on the other side of the pond, which is a shame, because those were some good times. ( This was all prompted by a report in my local paper today, for the record...)
