We've all heard the old saying, "If you have nothing nice to say, don't say anything at all."  But if you do have something nice to say, feel free to step up to the podium and let everyone around hear it. That's the idea behind this latest Improv Everywhere video. A lectern is set up in the heart of New York City and passersby are encouraged to say something nice.  Check out the video
