Cartoon debut Arthur's Substitute Teacher Trouble

Ms. Blank was an unseen substitute teacher for Mr. Ratburn's class, mentioned during a flashback in "Arthur's Substitute Teacher Trouble." She was unable to show up for class, and instead Miss Sweetwater was the substitute, letting the class color and have snacks.


  • It is likely Ms. Blank is a fictitious substitute teacher made up by Miss Sweetwater, who in turn, was the actual substitute teacher for Mr. Ratburn's class.
    • Her last name being a reference that she was never seen on-screen, combined with Miss Sweetwater's playful teaching styles could imply that the idea behind Ms. Blank is a lighthearted joke Miss Sweetwater wanted to poke fun with the class together.
