Deadpan is an adjective, describing a deliberately emotionless and otherwise impassive, matter-of-fact manner. It is also a form of comic delivery in which humor is presented without a change in emotion or body language. It is usually spoken in a casual, monotone, or cantankerous voice, and expresses a calm, sincere, or grave demeanor, often in spite of the ridiculousness of the subject matter. This delivery is also called dry humor or dry wit, when the intent, but not the presentation, is humorous, blunt, , sarcastic, laconic, or apparently unintentional.
