One day, I decided to reuse one of the available disks from the pool of previously used disks at work. On inserting it into the computer, I found that the disk had belonged to someone that I didn't particularly care for, so I erased the disk and renamed it "stupid". Some time later, I ejected the disk. When I finally tried to shut the computer down, I was greeted with the message "insert the disk stupid". There's a lesson there somewhere.
