Not myself but the most memorable one that sticks out for me.
Around year 10/11 in secondary school, my class and one other (both the high performing classes of the year) started holding wrestling matches in empty classrooms at lunch for a little while.
It was all kayfabe and people held their punches but as this went on you could tell people were starting to get stiffer with their hits as their was a unspoken rivalry between our classes (being the top 2).
One day I remember one of the guys from the other class, who was really tall and built, grabbed one of my class mates, got him in the position for a pedigree, took a few seconds to look across 'the audience' and then hit him with it. This was on that hard, almost marble looking style flooring you get at schools. My classmate got up, a bit dazzed and a bloody nose and that was the end of wrestling at school lol. As bad as it was, the way he executed it makes me laugh to this day, 20 years later 😂
Also I remember me and another guy from that class (the other tall and built guy in their class) randomly decided to 3D someone in technology class while everyone was standing around and the teacher was out. Guy wasn't hurt too badly and it was funny as hell.
You do have to remember how dangerous this shit can be though, worst was a thing people used to do while the class was lined up outside a classroom. Someone would run into the person at the back and try to domino the entire class. I remember doing it once but like half the class realised and moved out of the way, I eventually went into one guy, now with more speed and knocked him down. As he fell his back hit a small electrical box on the bottom of the wall and he was screaming and crying in pain. I thought at first I had paralysed him and was shitting myself. He was perfectly fine after but that really scared me straight lol.
