Soldiers Salute

One day a secretary noticed her boss’s fly was open.
Not wanting to embarrass him, she whispers in his ear, “Your barracks are open, and your soldier is saluting at the gates.”
The man, realizing what she means, decides to have some fun and says, “Do you see the colonel standing to attention?”
She whispers back, “No; all I see is a veteran sitting on his two duffel bags.”
