I was on a Cathay Pacific flight a few years ago and was looking at all the games they had in the in flight entertainment system. This was an older plane with really bad games, one of which was a number guessing game. I was bored and so wondered what would happen if I entered a negative number as my guess. The entire in flight entertainment system on the plane was down for a couple of hours until the crew figured out how to restart the system properly.
