She is an evil teacher, and is said to be the meanest there ever was. She was very strict, and if the students did anything she disliked, she'd turn them into apples.
In the TV Show, it is realized that she is responsible for Maurecia's tomboyish personality. Maurecia's pet porcupine, Fluffy, was also turned into a pineapple. Mrs. Gorf is also the reason for Maurecia's tomboyish personality today. From then on, the evil teacher was never, ever seen again. Oddly, before she turned Myron into a potato, she seemed to be inspired by Myron's rebbelion and hinted that she might be friends with him. She was defeated easily by Maurecia when she was overpowered by the transformed students.
- In Sideways Stories from Wayside School, there is a chapter called Mrs. Gorf about her turning all the students into apples. This chapter was adapted into an episode of the cartoon, but with many changes.
- In Wayside School is Falling Down, there is a chapter called She's Back! which shows Deedee in fear that she was on the monkey bars.
- Also in the second book is Another Story About Potatoes, where she appears in Joe's potato salad.
