secrets

A bald, bearded professor wearing glasses and a brown suit with a yellow tie stands holding a piece of chalk in front of a green chalkboard. The chalkboard reads: "(Number of people required to have a conspiracy) = 2" and "(Number of people on planet who can keep a secret) < 2." A caption below reads: "Professor Ericson disproves all conspiracy theories." Votey: an extreme close-up of a man's face drawn in loose black ink, eyebrows raised and mouth curled into a sly, knowing grin, with a speech bubble whispering: "Tell no one." The joke: he just told everyone the secret that nobody can keep a secret, while conspiratorially urging silence.
