I just remembered something horrible I did in middle school. I took basic electronics, which meant we did things like learn how to wind an electric motor. So we had really thin copper wire... which we quickly learned was great to wrap a invisible strand around things that needed to be plugged in... Not sure WHY I remember that, and I feel guilty about laughing at the memory...
@antares I think torturing the cussed is a perfectly acceptable activity. I got innocent teachers plugging in movie projectors, janitors plugging in vacuums, and any poor random undeserving souls I could target. For about a month, the school was plagued with this. I was horrid. I don't know why I suddenly remembered this, but I did this.
