We had a typing class in grade 9, using this old dos program. There was a ginger kid in my class that I originally tried to become friends with but he turned out to be an asshole, he was always bothering me etc. One time I reach over and hit CTRL+C and it just made the program go completely haywire on him, beeping etc. I think he even had to reboot the whole machine, it would just lock everything up. The program apparently did not take well to that command. The whole class basically consisted of both of us messing each other up while doing the typing exercises lol. I actually grabbed the whole program and put it on a floppy so I can practice at home lol. I wonder if I actually still have it somewhere, I need to look for it for nostalgia sake.
