In the above video, Norine Dresser answers the question, "What is the significance of ducks at a Korean wedding?" Although brief, I think it covers the basics well. I have to disagree with her on how she phrases the feelings of the "younger generation" about this tradition. She probably just meant that younger folks don't see them as being absolutely necessary part of the wedding ceremony. That's probably true, but we have also claimed this tradition for ourselves as well in new fun ways as Rick and Sara have (see our article on Navigating the Newlywed Years).
