The CIA has three candidates, two men and a woman, for one assassin position.
On the final day of testing, the CIA proctor leads the first male candidate to a large steel door and hands him a gun. "We must know that you will follow our instructions, regardless of the circumstances," he explains. "Inside this room, you will find your wife sitting in a chair. Take this gun and kill her."
The man is horrified, "You can't be serious! I could never shoot my wife!"
"Well," says the proctor, "you're definitely not the right man for this job then."
The CIA proctor leads the second male candidate to another large steel door and hands him a gun. "We must know that you will follow instructions, no matter what the circumstances," the proctor explains. "Inside this room, you will find your wife sitting in a chair. Take this gun and kill her."
The second man steadies himself, takes the gun and enters the room. After three quiet minutes, the man exits the room with tears in his eyes. "I wanted to do it -- I just couldn't pull the trigger and shoot my wife. I guess I'm not the right man for the job."
Finally, the CIA proctor leads the female candidate to yet another large steel door and hands her a gun. "We must be sure that you will follow instructions, no matter what the circumstances. Inside this room, you will find your husband sitting in a chair. Take this gun and kill him."
The woman takes the gun, enters the room, and before the door even closes completely behind her, she's fired off six shots. Then all hell breaks loose behind the door -- cursing, screaming, crashing. Suddenly, all goes quiet.
The door opens slowly, the woman exits, and wiping the sweat from her brow, she says, "Did you guys know the gun was loaded with blanks? I had to beat the son of a b**ch to death with the chair!"
