Headphoneus Supremus
I used to teach at two California Universities back in the 90's. I was also running my own business and consulting for a couple others at the same time. I can't tell you how many times I heard some jerk in industry say "those who can, do, and those who can't, teach." I loved looking at them and replying, "And only those with very exceptional skills can do both." That usually shut them up.
