Hidden talent?  As in "the super hot chick I spend time with when my wife thinks I'm playing poker with my buddies?"  Not exactly....but that's a killer idea!  

In this case, Hidden Talent refers to members of the Q101 Morning Show that contribute to the show, but for some reason want to remain "hidden."  Not sure if it's a Witness Protection Program thing or what?  Bottom line....if you're laughing while listening to the Q101 Morning Show, this crew had a part in making that laugh happen.
