The Great Union Square Laugh-In that was held in New York City this past Saturday, September 25, had participants falling over with laughter. Doug Collins, the man with the most contagious laugh, made a guest appearance as one of many unique laughers. The event was inspired by the filmmaker Albert Nerenberg's latest documentary, Laughology. The film discusses the benefits of laughter in our daily lives and the ever growing practice of Laughter Yoga. With the participation of various NYC laugh groups, onlookers were drawn towards the fun and encouraged to join in.
