There were three final agents, with only one of the three to be chosen for a very special mission. The Chief had to know he could depend on the final agent that would be chosen for the mission, to absolutely follow orders no matter what!
Independently and separated by a long hallway with many rooms, one by one he explained as much. To the first agent he said, "I am giving you this loaded gun. Inside the next room you will find your wife sitting in a chair. Go inside and kill her." In a minute or two the agent returned with regret and tears in his eyes "I'm sorry Chief, I just can't do it". The chief said, "Its ok, get your wife and go home."
The Chief went to the holding place of the second agent, If I choose you for this mission, I have to know you will follow orders no matter what they are, while placing the same loaded gun in his hand. "Inside the next room you will find your wife sitting in a chair. Go inside and kill her." After a longer period the second agent returned and said about the same thing. The Chief said "Its ok, get your wife and go home."
The Chief went further down to the long hallway to the holding place of the third and final agent and said the same while placing the same gun in his hand. "Inside the next room you will find your wife sitting in a chair. Go inside and kill her."
The third agent eaglery went into the room which held his wife, shut the door and the gun rapidly fired until empty. Then there was banging and cracking of chairs, rattling and knocking against the walls as of a big struggle, the sound of the table as it was being broken and splintering as it collapsed upon the floor.
Shortly the third agent with his clothes tattered, face scratched, some hair noticeable missing, opened the door and and said, "Chief; Would you believe some fool loaded this gun with blanks?" "She put up a heck of a good fight and it took some doing, but I finally got her pinned down and choked to death!!"
