Ancestry's running a website where you can (based upon marriage record entries) determine the chance that you get married in Los Vegas and the name of your spouse. Those who want to try their hand at the marriage game can do so here. Most of us have played the marriage game without ever heading to Vegas ;-)
I don't know about anyone else...but the odds I get married in Vegas are 0. This is closely tied to the odds that I enter a casino which are also 0 (for those who don't know, I live within shoutin' distance of numerous gambling boats on the Mississippi River and have never set foot in one. I have also never purchased a lottery ticket either. More proof that I descend from a bunch stubborn and contrary people). Actually I was taught that life was a gamble enough as it was and have had enough statistical and probability theory to KNOW who comes out ahead on the boat or in the casino.
Don't get me wrong, I love searching to find famous people in census and other records---more for the search than for anything else. And searching for someone else can give me ideas on my own lost people.
