Long story short, when I graduated high school the seniors got out on Wednesday to do graduation rehearsal. The sophomores and juniors still had class Thursday and Friday.
The school I went to had a big open air court yard in the center. Wednesday night A bunch of friends and I loaded up a pickup bed with horse crap. We drove across the football field and hid the truck behind a portable building. We then proceeded to hoist guys and the bags of crap onto the roof. We then spread the manure all over the courtyard along with a huge sign that said, "we took your $hit for four years here's ours!"
Hahahaha, that is a good one. I love it.
