A long time ago, I worked as an operator on an old IBM 370/Model 138 mainframe at a local college. My position had been reclassified to fall into a new area outside of the IT staff.
One day, my new supervisor entered the room and stared at the air conditioning unit directly behind me. He studied the two flashing lights for a few moments and asked what job it was currently processing.
I killed my career by replying, "Actually, sir, it's cooling the room. The computer is over there."
