Trivia

 * During Career Day in "D.W. Aims High", she can be seen wearing a safari hat, which suggests that she may want to become an explorer when she grows up.
 * Maryann was shown with Fern in the episode Sue Ellen's Little Sister as Fern's little sister. Fern, from what we've seen and known, is most likely an only child. Plus Maryann's father is very different compared to Mr. Walters.
