Today, we had a special mystery guest join us in studio for our segment "Who's Your Daddy."

Watch the video above as WGN's weatherman Paul Konrad and anchorman Larry Potash miserably fail at guessing the father of the mystery guest.

The mystery guest was Karen Knotts, the daughter of comedic actor Don Knotts better known as Barney Fife the deputy sheriff on The Andy Griffith Show.

Karen has a show Friday and Saturday at the Comedy Shrine in Aurora called "Tied Up In Knott."
