Continuity: Across the show, the number of kids in a class/what kids are in which class varies. For example, in "The Great Can Drive", the Ashleys are in Ms. Furley's class. However, in almost every other episode besides this one, the Ashleys are all in Ms. Grotke's class, and the exception are a couple of episodes in which 2 Ashleys are in Ms. Grotke's class, and the other 2 Ashleys are in another class (which is not specified by name), making a serious consistency error.
