You know the drill -- Jay Leno pulls some sort of "prank" on random people, and then we all are supposed to laugh at how dumb they are. Yaaaawn. Fortunately this time Leno's plan went awry, when the person he was attempting to startle turned out to be a talented, extroverted singer, who knows all the words to Bon Jovi's "Living on a Prayer."

Oh, and his wife can sing too. In fact, the audience loved them so much, that they actually got invited onto Leno's show. Some dumb bits *can* have a happy ending.
