With a pocket protector Kaftan? I think we have a winner! :D
I guess the evilest and most geeky thing I've done is what is referred to as my stereo prank
Back in the day, when I was in Sixth Form, our common room had a stereo in it. It was supposed to be for all of us to share and use equally, but there was a group of smelly boys that would insist on playing their music on it all the time and threatened to beat up anyone who went near the stereo. Me and my friends had had enough, so one day we came up with a cunning plan
The next morning I arrived early at school and conveniently had a screwdriver in my bag (because one does) and decided to unscrew the stereo plug and remove the fuse :D
It was so funny to watch them all try and figure out what was wrong with the stereo
