Sometimes what happens in Vegas doesn't stay in Vegas. Prince Harry had to learn that the hard way.

The city of sin is now capitalizing off of the prince's over-exposed weekend with cheeky ads (pun intended). Just days after Prince Harry's naked photo leak, companies quickly reacted with clever campaigns.

The Las Vegas Convention and Visitors Authority and Lynx deodorant are the first to launch new ad campaigns inspired by the naked royal rogue.

The Vegas tourism ads are now reinforcing the "what happens here stays here" policy and are threatening the partygoers who exploited the prince in all his nakedness. The ad launched in Us Weekly, just days after the scandal broke. In an Old Western style poster, the tourism ad laid down the law:

"For Shame! To those who traded in their pledge to their Las Vegas brethren, we deplore you. 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. Who's with us?"

Sin City is serious folks. The national party-leaders have coined the secrecy policy with the hashtag #Knowthecode. Of course, it's not to say one can never tweet, Instagram, or Facebook their Vegas moments. Vegas permits visitors to tweet about their fab hotel suite, their plate of Vegas-style food, and even some entertainment on the strip. However, wild photos of a royal are off-limits. That's all. Get the full details below.

In effort to promote this secrecy unity, Vegas encourages party goers to keep it cool. The ad reads, simply, "Keep Calm and Carry on Harry."

Lynx was just as speedy to react to the prince's plight. The deodorant brand takes full blame for Prince Harry's naked night. The ad suggests that it was Lynx's enticing scent that caused the ladies to go wild and rip of the prince's clothes. "Sorry Harry if it had anything to do with us," reads their latest ad, complete with an image of their body spray and a slightly tilted crown. Below the body spray reads, "The Lynx Effect."

Another industry trying to make some dollars off of the prince's royal bum is the pornography industry. Because of course, with naked celebrities come porno deals.

Vivid Entertainment, the leading adult film enterprise to capitalize on naked celebrities, has given the royal playboy and offer he will most likely refuse. Vivid Entertainment founder Steve Hirsch wrote a letter  (obtained by TMZ) to the prince offering him $10 million to star in a big budget adult film called "The Trouble with Harry." Hirsch assures the prince that "little Harry" will not be "minimized" in any way. Hirsch then closed the letter telling the prince to think of the "good it will do in the hands of the Prince's trust."

Prince Harry isn't the first to be exploited for his public dilemma; Kristen Stewart has it much worse. Robert Pattinson's cheating lady has bashing t-shirts made about  her. One shirt reads "Trampire" and another is just downright harsh --  "Kristen Stewart F*cking Sucks." At least this scandal is much more light-hearted. It could be worse Prince Harry, it could be worse.
