1. Get a big radio. 2. Load a CD with a sound track of a girl having an orgasm. Make sure there are 30 seconds of blank sound BEFORE the orgasm sound starts. This will give you 30 seconds of time to walk away and act natural once you start the radio. 3. Put the radio into a locker. 4. Lock the locker. 5. Using a remote control, start the radio. (do this while classes are in session) 6. Walk away and act like you have no idea what the hell happened. 7. The orgasm will start in 30 seconds, make sure you get to the end of the hallway and pretend you're doing homework on the ground! You get to watch all the teachers go WTF? :) 7. Laugh your ass off as students are laughing their asses off, and teachers are bewildered! Optional: A camera to record everything. You could upload it to Youtube and get popular! Why this prank isn't bad? It isn't vandalizing anything, it can easily be cleaned up, and the only effect will be the smiles on students' faces and the everlasting memories. there are usually a few lockers that people don't use. i'd put the radio in that of course i wouldn't put the radio in MY locker.
