Elizabeth tells Cody the story of the ugly duckling but changes it from it's classic telling. In the original story, the ugly duckling really was a swan and not a duckling. The way Elizabeth told the story it was a duckling who found he fit in with the swans and not the family he was born into.
At the end of the episode, Cody rips up his spelling certificate out of anger. Later we see it taped back together by Abagail and it's hanging on the wall. The show is set in 1910. Adhesive tape was not invented until 1925.
