They know when you're watching, they know when you're awake...
Long ago, and far away... A 400hz Motor-Generator set had a nasty habit of tripping off. We'd go down into the hole and pull the case, only to find no fault. So we'd dutifully close it up, report the lack of defect, and go about our day. Until it tripped again. After several cycles (heh) of this, the Chief finally tapped a picture of himself to the inside of the case. Never again did that particular unit trip offline. Because clearly, the machines know when you are watching them.
(No joke. True story.)
