Jackie: No, Dolfo, I need something right here, right now- like a knife or a stick.
Adolf: Hmmm. We must start ze planning at once... get into ze janitor's closet. You will find what you need in zere. Advance in pincer formation until you get to Paris, unt don't speak to ze Bolsheviks! When you are done, I will help you again. For ze Fatherland! Czechoslovakia as a nation has ceased to exist!
