Imagine that you've achieved an incredible accomplishment and personal dream - you've completed a storied career as a pitcher for the New York Mets. To you, there is no bar higher. You have a family, including a daughter, and then that daughter totally shows you up by competing on the world stage of the olympics. You'd be proud, but you'd also be like, "why I oughta." That's the story of Frank Viola and his daughter Brittany Viola, though I can't confirm if Frank Viola has ever said, "why I oughta."
Brittany started out as a gymnast, but didn't want to pursue the sport any further when she realized training would take her away from home. That's when she began to pursue swimming. She entered the olympics as a swimmer, doing very well in several events. That's how you do your father proud.
