During a May 2008 episode of Late Night with Conan O’Brien, Conan O’Brien paused mid show to investigate a single, unmoving presence in the audience who refused to laugh at anything. That presence turned out to be Nick Offerman, locked into an unblinking stare that immediately became funnier than the jokes themselves. Conan, clearly rattled, called out the situation in real time, noting that the show was doing just fine, thank you, and yet this one man had not cracked so much as a polite smirk. The bit spiraled into a perfect slow burn, with Conan trying harder, the audience laughing louder, and Offerman remaining gloriously unmoved, unknowingly delivering one of the most memorable reaction performances in late night history without saying a word.
