Shakespeare once said, "Brevity is the soul of wit." He probably should have just said "Be brief," but his point still stands: sometimes saying very little is more effective than saying more.
One of the better examples in history is when, at a dinner party, Federalist Andrew Jackson toasted that "Our Federal Union, It must be preserved," while segregationist John C. Calhoun retorted with a 35-word response that no one remembers.
Pro wrestling has an even better example than that:
Eddie Guerrero taught me that you don't even have to use words to get your point across. Sometimes the soul of wit...is silence.
