A dozen newlyweds pose for photos after participating in a mass wedding as part of a radio station contest at the Little Chapel of the Flowers on December 12, 2012 in Las Vegas, Nevada. Couples around the world are hoping that a once-in-a-lifetime event, the date 12/12/12, will bring added luck to their marriages if they tie the knot today. This will be the last such triple date for almost a century, until January 1, 2101. Photo: Isaac Brekken, Getty Images / 2012 Getty Images
