They finally get through all their written and physical tests when they are pulled aside by one of the instructors who takes them to a small room with a one way mirror in it looking into another room.
They bring the first guy's wife into that room and leave her there.
The instructor then loads two rounds into a pistol, hands it to the first man and says "Go kill your wife of five years."
The trainee takes the weapon, goes into the next room but comes back out 1 minute later and says "I can't do it."
The instructor replies, "Then you fail out - get out."
They then bring the second guy's wife into the room and leave her there.
The instructor then loads two rounds into a pistol, hands it to the second man and says "Go kill your wife of ten years."
The trainee takes the weapon, goes into the next room but comes back out 3 minutes later and says "I can't do it."
The instructor replies, "Then you fail out - get out."
Finally, they bring the third guy's wife into the room and leave her there.
The instructor then loads two rounds into a pistol, hands it to the third man and says "Go kill your wife of fifteen years."
The trainee takes the weapon, goes into the next room where there is silence for 1 minute.
Suddenly, there are two gunshot sounds followed by a huge commotion in the room.
The third man came out finally, sweating profusely, and says, "Good job, asshole!
You gave me blanks - I had to choke the bitch!"
