Jim Halpert: After you sir.
Dwight Schrute: No, thank you. I never let anyone walk behind me. 7 out of 10 attacks, are from the rear.
Jim Halpert: Ok, well that still leaves a 30% chance that I will attack you from the front.
Dwight Schrute: Yeah, but it will be easier to stop. I can always block the blow, or I can counter it.
