Well, not really an idea, but I've got a bit of a story to tell I suppose.
See, my area is...less than technologically advanced. Well see, our highschool had this jerkoff, we'll call him Jim, working in the technology department. On the school's main server, he had installed Novell Board Manager, something I'm sure some of you are familiar with as it's quite common. Well this past year, he began blocking every site imaginable. Now I can completely understand blocking porn, Myspace, Facebook, ect, but this idiot went as far as to block Yahoo, Disney, 911Tabs, and eventually, Youtube. Also, he blocked any site that had the words, sex, rape, drugs, ect, you get the idea. This was ofcourse a VERY bad idea, as an extremely large amount of legitimately educational sites were blocked. Every English teacher, infact, gave students a list of proxies to use to access such pages for research of court cases, historic events, ect.
Anyhow, the whole school was pissed. Teachers could no longer look up projects, business classes couldn't do their work, even the Ag and shop teachers wanted this guy dead. It all the way to the Principal wanting this guy out.
So, a friend of mine and I hatched a plan. If he was going to block us, we were going to block him. So here's what he did.
First, we took a sheet of 1/2" plywood and painted on it the message that popped up when you accessed a restricted site, "Organizational policies prohibit access to this page," as well as the matching logos, and such. It looked exactly like the Novel Board Manager page. Then, the night after prom at exactly 3:00am, we took this board to the technology department. Using brute force and a substantial amount of duct tape, we sealed his main door shut with the the board.
We then circulated an email detailing what we had done, yet keeping our identities hidden. Our little stunt was literally the talk of the school until the end of the year. It even made it into the school's newspaper, AND the local newspaper. After graduation, we questioned the principal about it. He simply stated that, "Who ever did it should be quiet until they receive their diploma, and then they should let me take them out to dinner."
