"CBI's Recruitment!" joke

The CBI is considering three men to be hired. They bring them in to speak with the interviewer separately. The first man comes in and sits down. The interviewer asks him:
"Do you love your wife?"
"Yes I do, sir."
"Do you love your country?"
"Yes I do, sir."
"What do you love more, your wife or your country?"
"My country, sir."
"Okay. We brought in your wife. Take this gun and go into the next room and kill her."
The man goes into the room, and all is silent for about 5 minutes. He comes back, with his tie loosened and he is all sweaty. He puts down the gun and leaves.
The second guy comes in and sits down. The interviewer asks him the same questions, and the responses are the same. The interviewer gives him a gun, and tells him to go kill his wife.
The guy puts the gun down and says "I can't do it..."
The third guy, Our Santa comes in, the same thing happens. The interviewer gives him a gun, and tells him to go kill his wife.
The guy goes into the room, and BLAM! BLAM! BLAM! BLAM! BLAM! BLAM! This is followed by a bunch of crashing sounds that end after a few minutes. Santa comes out of the room with his tie loosened, and puts the gun on the table.
The interviewer looks at him and says "What happened?!?!"
"The gun you gave me was filled with blanks so I had to strangle her!"
