You are walking down the street in a village in Northern France. You hear a muffled shot fired from several blocks away. Suddenly, a SS-car rounds the corner and stops sharply in front of you. Before you are able to react 4 soldiers and an officer jump out of the car aiming their guns at you. The officer walks towards you smiling and says. "Hallo Sir, I had been planning to kill ze first person zhat I happened upon this morning. Luckly for you, you are ze second person. I now give you a choice, either take this gun and kill one of ze children", indicating a group of children playing, "or I shall shoot both your kneecaps in and then kill you" He then pulls out a revolver and procedes to unload it except for one bullet. He then hands you the gun saying: "The choice is yours, Freund"
