Once, I worked as an operator on an old IBM 370/Model 138 mainframe at a local college. My position had been reclassified so that it fell into a new area outside of the Information Technology staff.

One day, my new supervisor entered the room and stared at the unit directly behind me. He studied the flashing lights for a few moments and asked what job it was currently processing.

I then ended my career by replying, “Actually, sir, it’s cooling the room. The computer is over there.”
