Poetic Terrorism
Sneak into your old high school with some accomplices (wear disguises and black head sock thingies), hold hostage the faculty by first binding them and duck-taping their mouths shut, and then proceed to the office unhindered. Make sure you have someone with you who is a techie or good at electronics, and program the bells so that they are constantly going off, and at about the 20th ring, say into the loudspeaker/school intercom system that school is officially being let out because of the observance of "Fuck institutionalized education and go artistically express yourself" day.
Afterwards, play led zeppelin into the intercom. When you are leaving, strip totally naked (except for the head sock disguise) and run around the school, get into a car, and drive as quickly away as you can. Have someone in your group take photos of the whole thing from beginning to end, then give them to the highschool newspaper to cover.
