Your comment reminds me of something I saw once. I worked a night shift in a video factory in London years ago when I was backpacking around Europe and running low on funds. At one point I was working next to a guy whos job it was to prevent videos going into a shrink wrapper crooked because they'd get stuck in the machine. Thing was, they were all going in straight anyway. The guy was so tired he'd occasionally try to "straighten" the odd video to show he was doing his job - it would then get stuck and start melting. Fortunately after about 20 mins of nodding off he actually fell asleep in his chair at which point everything worked perfectly. Here was a man who was more productive while asleep.
