When I was in my junior year in high school, my class put a skunk in the cafeteria and got the Homecoming Queen and King...and most of the cheerleaders in trouble. We dumped four BIG boxes of Tide in the Senior's ONLY Fountain, red dye in the swimming pool...and sprayed WD-40 all over the dance floor.
"We also stole all their dance music and replaced it with what I usually call 'elevator' music. We took the principle's car completely apart...and put it back together again on top of the building. Hee, hee...we even filled the tank with gas, chocked the wheels and left it idling...."
