In Surprise: Instant Xmas Carol!, celebrity carolers from across the entertainment spectrum hit the road in search of people who look like they could use a little extra holiday cheer. They then surprise their listeners with their own unique renditions of a classic Christmas carol; some good, some bad and someÂ well, you know. The result is a holiday special packed with unforgettable songs performed in often wild and unpredictable situations.
