After photos of the Prince playing strip billiards at Las Vegas' Winn hotel made its way to the internet and cover of the The Sun, Sin City, itself, is outraged that a photog broke the code: "What happens in Vegas stays in Vegas!"

Never one to overlook a marketing opportunity, the Las Vegas Convention and Visitors Authority too out a full-page ad in USA Today that reads, in huge letters, "FOR SHAME! TO THOSE OF YOU WHO TRADED IN THEIR PLEDGE TO THEIR LAS VEGAS BRETHREN, WE DEPLORE YOU."

The ad continues:

We are calling on you, the defenders of what happens in Vegas staying in its rightful place -- in Vegas. We are asking for a shun on these exploiters of Prince Harry. We shall boycott partying of any kind with them. No bottle service. No bikini clad girls. No Bucatini from Batali. In other words, we will not play with them anymore.

Vegas travelers are encouraged to submit an oath to follow the code on Las Vegas' official website.
