You've seen them before - maybe in person, maybe on television. Someone who, at first look, appears to be nothing special (if that good), and they suddenly find themselves in the spotlight.

As the moment unfolds, we ask ourselves, "Is this going to be something magical or a complete train wreck?" Then, they step into that spotlight - and become famous for all the right reasons.

I have three examples of "Susan Boyle Moments." One of which, of course, is the obvious one.

Example one: In 2013, Michael Pollack was a freshman at Vanderbilt University. Billy Joel was there doing a Q&A, and Michael, a pianist, asked Joel if he could accompany him on his classic song, "New York State of Mind." Joel agreed.

Michael Pollack did not let his moment in the spotlight go to waste:

Example two: Also in 2013, Sarah Horn was a college voice teacher and a big fan of Broadway star Kristin Chenoweth. Sarah went to hear her idol perform at the Hollywood Bowl. A standard part of Chenoweth's concerts was to pick someone out of the audience to sick the duet, "For Good" from the musical Wicked with her.

That night, Kristin picked Sarah, and she did not disappoint.

Example three: Of course, is the 47 year old Scottish spinster who stepped onto the stage of Britain's Got Talent in 2009. Her appearance and her attitude had the judges smirking to themselves.

And then, Susan Boyle started to sing
