The CIA had an opening for an assassin. After all of the background checks, interviews, and testing were done there were three finalists...
Two men and a woman.
For the final test, the CIA agents 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.
In side of this room, you will find your wife sitting in a chair. Kill Her!!!"
The man said, "You can't be serious. I could never shoot my wife."
The agent said, "Then you're not the right man for this job."
The second man was given the same instructions. He took the gun and went into the room. All was quiet for about five minutes. Then the man came out
with tears in his eyes." I tried, but I can't kill my wife."
The agent said, "You don't have what it takes. Take your wife and go home."
