A CIA officer was interviewing 3 candidates for an open position.
He explained to each of them, "In the next room is your mother. Take this
gun, enter the room, and kill her."
The first candidate became pale and quickly declared he simply
couldn't  do such a thing. The officer thanked him for his time
and excused him.
The second candidate took the gun and went into the room. Ten minutes
passed with no sound or anything. Finally, he came out without shooting
his mother. He told the officer he simply couldn't do it and left.
The third candidate took the gun and briskly walked into the room.
Seconds later three shots blasted out from the room. Shortly after
a scuffle ensued inside the room. The officer looks surprised and just
as he is about to go in, the man walks out. "What idiot put blanks in
the gun?! I ended up having to strangle her!"
The officer cooly replied, "you're hired".
