I think the most interesting thing that happened to me at high school wasn't at the high school, it was at the tech center (which is basically an epic version of electives that you had to apply for, things like cisco networking, cooking, 3d animation, adv. CAD, most hvac-related fields, car repair, etc)
So it was the the very near end of last school year, and there was all of 5 or 6 people in class since at that point, you don't go to tech unless you have a reason, like certifications. We have a server or three in our lab (we being the cisco class), the IT guy at the tech center is friends with both teachers of ours (and everyone that was there that day, though not as much since we only saw him occasionally), and the class across the hall, 3d anim, wanted to see if the rendering worked well enough to use the servers some of the time as a render farm sorta thing. To test this, we of course need to take the requisite cables across the hall, and attached them temporarily to the ceiling. In the middle of this, the IT guy comes up the hall (the place is basically a giant squared C with an additional structure attached when they needed more space, so this isn't exactly rare) and says something like "I feel like I should say something about this, but I'm not sure what."
Then basically everyone else in the middle area of the C heres him comes to see why we're attaching ethernet cables to the ceiling of the main hallway with paper and zip-ties.
