Oscar: Dwight, what are you telling this girl?
Dwight K. Schrute: The truth.
Oscar: Stop filling her head with nonsense, okay? She doesn't know any better.
Erin: Oscar, I am so glad you just got here. I would've believed everything he said.
Dwight K. Schrute: No, no, no! You're filling her head with nonsense. You and the history books. I'm telling the truth.
Erin: Interesting.
Dwight K. Schrute: Yes, thank you. All of history has been whitewashed.
Oscar: Really? Why don't you tell us the real history, Gore Vidal?
Dwight K. Schrute: Okay, I will. I don't know who that is, but I'm gonna tell you this-
Oscar: He's a historian.
Dwight K. Schrute: Gettysburg was very important. Credit where credit is due, okay? Big, mad props to Gettysburg. Was it, however, the most northern battle of the civil war?
Oscar: Yes, yes, yes!
Dwight K. Schrute: Not by a long shot!
Erin: No!
Oscar: Yes!
Dwight K. Schrute: No, it was not!
Oscar: Argh!
Dwight K. Schrute: No, it was not. Was it the second-most northern?
Oscar: What?
Dwight K. Schrute: Sure! I will cede it was the second-most northernmost battle!
Oscar: Erin-
Dwight K. Schrute: Was it the northernmost? No. Get out of here, Oscar.
Erin: Get out of here!
