A sergeant was passing the barracks after lights out, when
he heard some voices from inside. He slammed open the door, and shouted: Listen,
you guys! A few minutes ago, you all heard me say good night. What you must
realize, is that when I say "Good Night," what I really mean is "Shut up!!!"
The room instantly fell silent. But after a few seconds,
a small voice could be heard from somewhere in the far back of the dark room:
"Good Night, Sergeant"
