Quote from Dwight K. Schrute in After Hours
Jim: I don't know, Dwight, I think maybe you should check again. Dwight K. Schrute: Nope, I wasn't bitten. Jim: Well, maybe it isn't warm enough in here. Dwight K. Schrute: Oh, it's plenty warm, and I was farting continuously under the sheet, creating a kind of greenhouse effect. Jim: Come on. Dwight K. Schrute: If there were any in here, they would've embedded themselves in me.
