It’s going to happen to all of us at some point in our lives — usually when we let our guards down, and, of course, when we least expect it. It may happen so quickly that a few of us won’t even realize what happened until it’s over.What I’m talking about are those brief, self-aggrandizing moments when the whole world is our oyster. For most, these 15 minutes of fame will come to us at no cost. We simply have to live our lives and be ourselves — fate will do the rest.Others are willing to go to great lengths to achieve their fame.But what is the true cost of that quarter-hour of fame?Jon and Kate — with the eight kids and failed marriage — tried their luck at it and their 15 minutes came to a crashing halt when their lives imploded on national television. In a similarly ridiculous episode, Richard and Mayumi Heene contrived a story that their son floated away in a homemade hot air balloon. After a 50-mile, hours-long chase of the balloon and the following frenzied media storm, their son was found above their garage.  Needless to say, the rest of the Heene’s 15 minutes will be spent in court.Most recently, we saw Michaele and Tareq Salahi crash President Obama’s first state dinner, evading the Secret Service and starting a media frenzy in the process. The thing with fame is that people get so caught up in obtaining it, they forget to be unsung celebrities of the real world: parents who actually raise their children, community volunteers, teachers, doctors, police officers, firefighters, the friend who will always be there and all the others that make our world a semi-habitable place.They are the real celebrities of the world, and their 15 minutes should never end.
