I worked IT in a high school for about 10 years. Here are some of the doozies:
- weed stashed in a PC case
- pop tart jammed into a DVD drive
- illicit domain admin account created by a student worker
- script to set porn to be the default background on reboot.
I still haven't fully figured out the fridge after a year and 7 trips. We invested in a separate canopy with screen walls and that's a lot more reliable than the awning.
