Quote from Dwight K. Schrute in The Duel
Jim: What are you standing for? Dwight K. Schrute: If I'm sitting, I can't disable his neck or his groin. Jim: You're not gonna do anything to his neck or his groin. Dwight K. Schrute: If I'm sitting, I don't have the option to. Jim: I'm in charge when Michael's gone, and I need you to sit.
