Quote from Jim in The Fight
Jim: [on the phone] Right. Oh, let me just check the pricing list. Hold on one second. Dwight K. Schrute: [also on the phone] Sensei, hello, it's Sempai. Dwight. Jim: You know what, let me give you a call right back. I'm gonna find it and then I'll call you back. Thanks. [hangs up] Dwight K. Schrute: Yes, I just had a question. Yes, Sensei. [speaks Japanese, then hangs up] Jim: Was that your mom? Dwight K. Schrute: No, that was my sensei. Jim: Oh, I thought it was your mom. Dwight K. Schrute: I am now Sempai, which is Assistant Sensei. Jim: Assistant to the Sensei, that's pretty cool. Dwight K. Schrute: Assistant Sensei.
