the zipper

[eman]

A man walked into a supermarket with his zipper down. A lady cashier
walked up to him and said, "Your barracks door is open."
Not a phrase that men normally use, he went on his way looking a bit
puzzled. When he was about done shopping, a man came up and said,
"Your fly is open." He zipped up and finished his shopping.
At the checkout, he intentionally got in the line where the lady was
that told him about his "barracks door." He was planning to have a
little fun with her, so when he reached the counter he said, "When
you saw my barracks door open, did you see a Marine standing in there
at attention?
The lady thought for a moment and
said, "No, no I didn't! All I saw was a disabled veteran sitting on a couple of old duffel bags."
