we did several pranks.
1.) we TP'd the trees, egged the walls, drew on the floor and walls with chalk and shaving cream.
2.) we let chickens out onto the school so the teachers had to catch them.
3.) we brought our dogs to school and let them play.
4.) we got up out of class at 11:45 exactly, met at the middle of the school, and walked out the school together so the police couldn't stop us.
