For my other stunt (see my "C64" post also on this page), I got in early to the library room in 5th grade (1983). They had 20 or so Commodore PET computers for us to use to learn from. The teacher was going to have us play Oregon Trail and had already preloaded the game into the memory of all the machines. A simple LIST of the program revealed the supplies you had available. Another command to update the line (lines?) of code to change supplies (Oxen becomes Monkeys, Bullets becomes Bubble Yum, you get the idea). Once we all started playing, the confusion and giggling ramped-up pretty fast. It didn't take long for the teacher to figure out the perpetrator. It was the first time I had to stay after school.
