Quote from Dwight K. Schrute in The Fight
Dwight K. Schrute: I am a practitioner of Goju-Ryu Karate here in Scranton. My sensei, Ira, recently promoted me to purple belt. And gave me the duties of a sempai. Not that a lot of people here in America know what a sempai is. But it's equally as respected as a sensei.
