Back when I was in high school, On one Friday afternoon I discovered the ethernet cables connecting the computer to the network had the same plug on both ends. I wondered what would happen if I had a cable coming out of the wall plugged back into the wall, so I pulled out the cable out of one of the computers and plugged both ends into the wall. On Monday, One of the teachers went to each class and (loudly & angrily) asked "Who was it that pulled the cable from one computer and plugged it into the wall?!". It was only when they got to our class, I realize something was wrong because of something I did, so I timidly said "I did". Well, as you might have guessed, what happened was a short-circuit and all the computers in the school couldn't connect to any network anymore. The office staff lost all their current work and had to work for extra 4 more hours each, doing office work manually. They didn't find out what was the problem until Monday. The principal asked me why I did it, and I answered "I was curious." Due to my "stellar" past performance and history at the school, I was fined $300 (the cost of the technician) and sentenced to 2 days suspension. I was told that if I was any other student I'd have been expelled. My lesson that day was: "If you ever muck with stuff for fun, PUT IT BACK TO IT WAS BEFORE." My school record indicates I have been put in detention 0 times and suspended 2 days in total.
