We were evil in 6th form...
When I was in 6th form, our classes were used as isolation rooms for the disruptive kids from lower years. Mostly upon being put into a room full of us they would sit down and shut up.
One guy sticks in my mind however. He would regularly end up in our physics lessons. On one occasion, Mr J (our teacher) had to go out of the room, leaving us, the isolation guy and a van de graafe generator in the room. Unsupervised.

I don't remember the exact chain of events, but it ended up with the isolation kid standing in a polystyrene box, touching the generator. For about 15 mins before Mr J came back. His reaction was classic.

Upon re-entering the room, he asked us 'How long has he been holding that for?'. Upon hearing the response, he asked the kid 'Do you know what that is?' When the kid claimed not to, he went and fetched his teacher from over the corridor, who promptly laughed at him, and explained his predicament and turned off the generator.

After the kid had been discharged, Mr J turned to us, and told us 'If we ever do that again, he will be discharged through you. But good work boys'.

I never saw that particular kid in our lessons in isolation again. I am also told that he couldn't feel his hand for most of the day.
