Michael Scott: And I'd like to start today by inspiring you. May I borrow someone's textbook, please? [A student hands Michael his text book] Thank you. What have we here? Ooh, economics. Very, very interesting. [rips pages out of the textbook] You cannot learn from books. [still ripping] Replace these pages with life lessons, and then you will have a book that is worth its weight in gold. I know, those are expensive, but the lesson is priceless. Good. All right, I think you're inspired. Shall we proceed? There are four kinds of business, tourism, food service, railroads and sales. And hospitals/manufacturing. And air travel.

Michael Scott: Yeah, sure. You know business. Sitting up here in your ivory tower and your ebony tower. Well, you know what? I tell you one thing, Dunder Mifflin is here to stay!
Student: But how can you compete against a company with the resources of a nationwide chain?
Michael Scott: David will always beat Goliath!
Student #2: But there's five Goliaths. There's Staples, OfficeMax-
Michael Scott: Yeah, yeah. You know what else is facing five Goliaths? America. Al-Qaeda, global warming, sex predators... mercury poisoning. So do we just give up? Is that what we're learning in business school?

Michael Scott: A boss is like a teacher. And I am like the cool teacher. Like Mr. Handell. Mr. Handell would hang out with us, and he would tell us awesome jokes. And he actually hooked up with one of the students, and then, like, 12 other kids came forward. It was in all the papers. Really ruined eighth grade for us.
