Quote from Dwight K. Schrute in Traveling Salesmen / The Return
Jim: After you, sir. Dwight K. Schrute: No, thank you. I never let anyone walk behind me. Seven out of 10 attacks are from the rear. Jim: Okay. Well, that still leaves a 30% chance that I'll attack you from the front. Dwight K. Schrute: Yeah, but it'll be easier to stop. I can always block the blow. Or I can counter it-[Jim slaps Dwight's face]
