Mrs. Drone

Mrs. Bofini was a past substitute teacher for Mr. Ratburn's class. The class disliked her, because she had the habit of chewing an apple with her mouth open in front of the class, plus talk while she was eating, and blinking her eyes. During the flashback, she told Mr. Ratburn's students to spell the word "leather", but her habits distracted them from spelling. She was ranked #2 of the worst substitute teachers behind Ms. Tremello, according to Arthur and his friends.
