The Zipper

[Nick]

A man walked into a supermarket with his zipper down. A cashier walked up
to him and said, "Your barracks door is open."

Not a phrase with which he was familiar, 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 quickly 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 happen to notice 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".
