Help me pull off the neatest senior prank ever!

[Jessweeee♪]

I didn't take place in a single high school tradition, so it's been so very uneventful and boring. Thought I'd do something fun.


The part I need help with involves hijacking the school's PA system and playing music and other things constantly. How do you all suggest I go about doing such a thing?


I know I will definitely need help from other students. Problem is, my friends are flakes and blabbermouths so I can't rely on them. I might be able to get help from my cousin and my brother, now that we're all going to the same school. I know of at least one person who might have helpful information. How do I approach someone about this? xD


EDIT:

I also thought it would be neat to have a surprise rave, but there's no way that I could get the lighting and audio equipment that I don't have int he building unnoticed, and I don't think I can knock out the school's power xD


Current Neat-o Idea of the Now:

YouTube - pacman school prank


My brother will help on the grounds that he is pacman, so I've got two people already! Currently researching how to make the costumes.
