Nick and Molly have a wonderful surprise for Margaret- a bike! Trouble is, Nick and Molly don't know much about current fashions in bikes, instead of a ten-speed racer, they buy her a great balloon-tired antique that makes her a virtual laughing-stock among her pals. Afraid of hurting Molly's feelings, Margaret tries ways of her own to get rid of the ugly duckling, and, in the process, learns something about conformity - when it's good and when being different isn't so bad.
