Hearing the VM joke reminded me of what a co-worker once did. He taught a VM class to Operations one day, explaining the VM concept of 'virtual' vs 'real' devices. Everyone got it, except the first shift OPs supervisor. It was generally agreed she had not gotten her position by technical aptitude. He tried explaining the concept a few more times, then had to move on. She threw a fit, saying it was his fault, he wasn't a good teacher, etc.. He apologized, smiled, and finished the class. Later that day, a myster- ious thing happened: a mag-tape mysteriously appeared on the old dusty CDC card-reader (maybe it was a paper punch !!) in the corner. It was threaded to an empty 'take-up' tape spool that was also 'jury-rigged' to the side of the old punch. Underneath, a large sign was taped. It read: VIRTUAL TAPE READER No person ever owned up, but I have my suspicions.
