When speaking, be sincere, be brief, and be seated.

The line is a compact piece of advice about public speaking: tell the truth, don’t ramble, and know when to stop. Its humor comes from the blunt final imperative—“be seated”—which punctures the self-importance that can accompany speeches and meetings. Read more broadly, it reflects an ethic of disciplined communication: sincerity builds trust, brevity respects the audience’s time, and ending promptly signals self-control. The maxim is often invoked in civic and organizational settings as a corrective to long-winded or performative rhetoric, emphasizing that effectiveness in speech is measured as much by restraint as by eloquence.
