Actors, comedians, and improvisers Thomas Middleditch and Ben Schwartz feel both sizzlin’ and curious about being Conan O’Brien’s friends. Thomas and Ben sit down with Conan this week to talk about their two-man improvised show (plus Conan’s own improv history), playing off mistakes in the moment, performing at Carnegie Hall, and cross-theatrical integration. Later, Conan responds to a listener voicemail regarding celebrity codenames.
