Filmmaker Rob Stewart stopped by the show to share his Best Story Ever - the tale of a young man who was overweight and had trouble speaking, who discovered a whole new world underwater.
Eventually, that led him to filmmaking, where he's made a living telling people about issues close to his heart.
Rob's latest film, 'Revolution', is in stores this Tuesday, August 20.
