"Opening for an Assassin" joke

A few months ago, there was an opening with the CIA for an assassin.
These highly classified positions are hard to fill, and there's a lot
of testing and background checks involved before you can even be
considered for the position.
After sending some applicants through the background checks, training
and testing, they narrowed the possible choices down to two men and a
woman, but only one position was available.
The day came for the final test to see which person would get the
extremely secretive job. The CIA men administering the test took one
of the men to a large metal door and handed him a gun.
"We must know that you will follow your instructions no matter what
the circumstances," they explained. "Inside this room, you will find
your wife sitting in a chair. Take this gun and kill her."
The man got a shocked look on his face and said, "You can't be
serious! I could never shoot my own wife!"
"Well," said one of the CIA men, "you're definitely not the right man
for this job then."
So they brought the second man to the same door and handed him the
gun.
"We must know that you will follow your instructions no matter what
the circumstances," they explained to the second man. "Inside you will
find your wife sitting in a chair. Take this gun and kill her."
The second man looked a bit shocked, but nevertheless took the gun and
went in the room. All was quiet for about five minutes, then the door
opened.
The man came out of the room with tears in his eyes, "I tried to shoot
her. I just couldn't pull the trigger and shoot my wife. I guess I'm
not the right man for the job."
"No," the CIA man replied. "You don't have what it takes. Take your
wife and go home."
Now they were down to the woman left to test. Again they lead her to
the same door and handed her the same gun.
"We must be sure that you will follow instructions no matter what the
circumstances. This is your final test. Inside you will find your
husband sitting in a chair. Take this gun and kill him."
The woman took the gun and opened the door. Before the door even
closed all the way, the CIA heard the gun start firing, one shot after
another, for 13 shots. Then they heard screaming, crashing, and
banging on the walls. This went on for several minutes, then all went
quiet. The door opened slowly, and there stood the woman.
She wiped the sweat from her brow and said, "You guys didn't tell me
the gun was loaded with blanks! I had to beat the S.O.B. to death with
the chair!"
