This tho:
Back in the day I worked in for small startup in the Purdue research park. The professor who's idea started the company would do tours, and as the IT guy, I just spent my time in the server room, where we had one rack filled with a few switches and maybe a couple 1U servers. Well the professor would ALWAYS open the door to the server room and show off the pretty blinking lights of the switches which actually never failed to amaze the onlookers. He usually gave some description of what those blinking lights meant, which was invariably wrong, but hilarious. No one ever called him out on it, so it seems that the people on his tour were technical in ways other than computers and networking.
