Behind the scenes
- Professor Egg visited Hogwarts School of Witchcraft and Wizardry, during the winter of 1993 for unknown reasons.
- It is possible that he was the male Muggle Studies teacher replaced by Charity Burbage, thus explaining both his knowledge of Muggles and his presence at Hogwarts. Another possibility is that he gained his title through his work at the Institute of Muggle Studies.
