I remember something along these lines. Semper Fi.
A young boy and his family were waiting out a long lay-over at a busy airport. The boy noticed a spit and polish Marine in his dress uniform. The youngster walked over to the Marine, and overwhelmed by the impressive figure, expressed his admiration, "Wow!!!" was about all the kid could utter, as he stood staring at the Marine. The Marine felt a sense of pride at the kid's admiration, and grabbing his snow white saucer cap with the highly polished bill, said, "Here kid, why don't you try this on..."
The youngster donned the cap, and although it was too big for his head, began to cockily strut up and down the concourse at the airport, wearing it. The kid strayed into a men's room where he saw a Ranger standing at the urinal. Decked out with his black beret, blue infantry cord, CIB, combat patch, and stack of ribbons and badges. The kid walked up to the Ranger, and as just with the Marine, was overtaken by admiration..."Wow!!!!" marveled the youth.
"Blow me, kid," stated the mannerless Ranger.
"Oh no sir, it's not like that," said the kid, "I just borrowed the hat!"
