Quote from Phyllis in The Seminar
Dwight K. Schrute: What are some of your small business ideas? Old Guy: I was thinking we could buy up of abandoned mine shafts. Phyllis, Stanley & Dwight: [unenthusiastic] Ooh. Dwight K. Schrute: That's great. There's a big, big future in that. Phyllis: A lot of mines in Scranton.
