3. Mrs. Hoover
20th Century Fox TelevisionMrs. Hoover is a teacher at Springfield Elementary. Since she teaches second grade, most of her interactions are with Lisa and sometimes with Ralph (typically with hilarious consequences). However, she doesnt really get any of the credit for the laughs because her partner is the one usually doing all the work. There are a few reasons why a character like Mrs. Hoover should work. She is completely apathetic and hates her dead-end job. Many people can relate with that, but yet her character is still nowhere near what she could have been. Lisas class is featured just about as much as Barts class in the show but there is a huge discrepancy when you compare Mrs. Hoover with Ms. Krabappel in terms of how well-developed their personalities or their backstories are. There was once a moment when Hoover received tenure and decided to let Ralph teach for a little while and, honestly, it would have been a lot better if they just stuck with it. After all, how else are we going to find out what year 1+1 was in?
