This is a very involved prank that took weeks to plan and ended up getting three people expelled, but hilarity ensued after we pulled this off. After a wrestling practice, members of the senior class (actually about 30 people out of our senior class), were let into the building at night by the wrestlers, who were staying late. We got lucky in that the coach just left and there were no security patrols of any kind. We got into the room of the one teacher in school that we absolutely hated...and it just happened that his third floor room is strategic in that right out the window is the lower second floor roof. So, we moved everything from the classroom onto the roof and superglued everything to the roof. We set up the classroom just like it was inside, but instead put it on the roof. We moved cabinets, books, even the teacher's desk. Now, you may ask yourselves how we got desks and cabinets out through the windows...all I can say is thank god for those removable science windows...we coulda put a building through those suckers..lol.

The entire room was left empty and when the teacher showed up the next day he saw the entire class out on the roof acting like nothing happened. I thought he was gonna drop dead right there......it was great.
