Once 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 I/S 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."
