Three men and a beautiful woman

Question: Three men were told by God, " If you step on a duck, you shall marry the ugliest woman. However, if you do not step on a duck, you shall marry the most beautiful woman in all the land." The three men accepted. The first man stepped on a duck from not paying attention. The second man accidentally stepped on a duck in his son's room. The third man never stepped on a duck and was then married to the most beautiful woman he's ever seen. But why was he really married to the beautiful woman?
