"The factory doesn't like to hear too much talk about things it doesn't believe in. Contrary to what you may have heard, the factory has never found a single problem caused by ghosts. So if you meet any ectoplasmic spirits up there in the high crane, I suggest you be polite and they'll probably be polite right back. You're up there alone for fourteen hours a day, and you might find it's nice to have someone to talk to."
