In the school we were using slow PCs for learning MS Office things. Every single step we did took ages. There were one guy who was an informatics antitalent: he never were able to work fluently with any electric machine from a microwave to anything smarter. In addition he was a semi-pro athlete and he had some kind of anger management issues, sometimes yelled to the teacher after a bad mark or with us when we lost a in-school soccer match. You know, he was that competitive guy.
One time on computer science class he was very focused. He tried to follow every steps precisly and his machine seemed faster than as usual. He felt like he broke some kind of wall which was between he and the machine.
When we had a break and he went out we tought that we should make a prank. We made a fullscreen screenshot from the desktop and set it as the wallpaper, then killed explorer.exe. As a result the icons and the start menu was only on the screen by the wallpaper.
When he came back he said that there were some bad news from some of the sport event he wanted to go, so he was angry. But then... You know the gif when the guy first hit the side of the screen multiple times then throws out the machine? Yeah, we saw that in real life, but not in that office. First he was just clicking everywhere, we just watched how his face just transforming. Then he started to talk just in himself as the machine could understand. After two minutes he just yelled to the machine why did it freeze, but the last drop was when the teacher said: You'll have to send me your work and it will be marked. In this moment he was just roard a huge and droped the CRT out of the window from the second floor. Luckily the window was facing to a brushy part of the garden so no one was there. He just standed there, looked out to the CRT sitting in a brush for a while, then he turned to the teacher as "Mr, I think something is wrong with my machine"
