They gave all the kids in my grade this extracurricular assignment thing where we watched an episode of The Twilight Zone and then wrote a report on it, but the teacher had trouble playing the video so I sent them a rickroll link disguised as the link to the video, he clicked it, and since it was an MS Teams meeting, everyone was watching and got rickrolled.
I also make the printers in the teacher’s lounge print hentai and I haven’t got caught.
