The Manager hired a new secretary,  she was young, sweet and polite.  One
day while taking dictation, she noticed his fly was open.  While leaving the
room, she courteously said, "Oh sir, did you know that your barracks door is
open?"
He did not understand her remark, yet latter on he happens to look down and
saw that his zipper was open.  He decided to have some fun with his new
employee.
Calling her in, he asked, "by the way, Miss Jones, when you say my barracks
door open this morning, did you also see a soldier at attention?"
The secretary, who was quite witty, replied, "Why no sir, all I saw was a
disabled veteran sitting on two duffle bags."
