Cal learns how we all can bring some happiness into our lives from a man who became a national and international whistling champion. Chris Ullman has whistled in the Oval Office, whistled on The Today Show and The Tonight Show, and whistled with a symphony orchestra in front of 60,000 people. His message boils down to this: It’s hard to be unhappy when you’re whistling a happy tune. Chris brings joy to people almost every day with a Happy Birthday serenade. It will be hard for you to walk away from this episode without whistling yourself.
