City of Las Vegas : Know the Code

After Prince Harry was photographed playing strip billiards and cavorting with "party girls" in a Las Vegas suite, the City of Las Vegas has launched a cheeky tactical ad campaign that shames the photographers who violated a key tenet of the Sin City Code: What happens in Vegas, stays in Vegas.

The City took out an ad in USA Today that begins: "For Shame! To Those of You Who Trades in Their Pledge to Their Las Vegas Brethren, We Deplore You," and goes on to ask the customers of Vegas to shun those who violate the code by photographing English royals in compromising positions. "No bottle service. No bikini clad girls. No Bucatini from Batali. In other words, we will not play with them anymore," it reads.

Vegas partiers are encouraged to go to the "Know the Code" website to "take an oath" and also ties in some tourist information about all the things you can do in Vegas that you are allowed to safely write home about. The Vegas airport has also supposedly put up a sign that reads "Keep calm and carry on, Harry."
