If you are your own worst enemy, don't do yourself any favors. — Tom Heehler

Big professorial words are good to know but not necessarily use at every turn. Try not to serve vichyssois to a coal miner, and do not give Cheerios to the queen of England. Neither will be amused.

Fear not the tyrant; fear the tyrant's wake.

The educated don't get that way by memorizing facts; they get that way by respecting them.
