You know the rest of the line. What happens in Vegas stays in Vegas. And being the uncreative copycats that most people are you have probably seen this misguided advertisement ripped off and used on t-shirts all over the country. I have seen shirts for Sullivan, Illinois which read what happens in the corn field stays in the corn field (I don't even want to consider the possible meanings that could have). I have seen Cubs t-shirts what happens in Wrigley... And Cardinals what happens at Busch... All of which are lies, especially the last two examples since the ball games are on television for the world to see.
I do think that it would be an accurate advertising slogan for many of our churches. "What happens at Second Assembly of God stays at Second Assembly," because so much of what happens during our services is not reflected in our lives on a daily basis. And that is just as pathetic and even more inexcusable than someone believing the lie about Las Vegas.
