Arthur's Substitute Teacher Trouble

Arthur's Substitute Teacher Trouble is the second half of the 27th episode in season 1 of Arthur. It originally aired on April 28th, 1997, along with "D.W.'s Blankie".

Summary
When Mr. Ratburn's sister substitutes for him while he is sick, she makes school so easy that it becomes boring.

Plot
The episode begins with Arthur and Buster carrying a huge stack of books and papers home from school. Arthur begins to complain about how difficult Mr. Ratburn is as a teacher because of the enormous amount of homework he assigns.

He goes on to tell how Mr. Ratburn once managed to turn a routine trip to the zoo into class time, much to the dismay of his students. As they continue walking, Buster trips on a crack in the sidewalk and falls into a mud puddle, losing his work. He tells Arthur that he wishes Mr. Ratburn would just disappear sometimes.

During a routine day in class as Mr. Ratburn teaches his students, he begins to show signs of losing his voice. While the kids are at recess, he tries to tell Mr. Haney he won't be able to continue teaching the class, but loses his voice before he can say so. Mr. Haney sends Mr. Ratburn home on sick leave and announces to the class that they will have a substitute teacher until Mr. Ratburn returns, much to the excitement of the students.

Arthur and his friends wonder who the substitute will be, and recall a few past stand-ins they didn't like. First was Mr. Elkin, whose big antlers accidentally knocked several of the kids out of their seats. Another was Mrs. Bofini, whose loud chewing of an apple made it impossible for the kids to concentrate on their work. Then there was Ms. Tremello, who mumbled everything so the students couldn't understand her. She was considered the worst of the three.

Their favorite substitute was Ms. Blank, who apparently never showed up to teach the class. Miss Sweetwater filled in for her, and let the kids color and have snacks all day. Hopeful that Ms. Blank will come back, the kids are horrified when Mr. Haney names their substitute: Miss Rodentia Ratburn, Mr. Ratburn's sister.

After school the kids wonder what Miss Ratburn is like, figuring that since she is Mr. Ratburn's sister she is probably as tough or even tougher than him. The kids begin thinking up ways to get out of class if Miss Ratburn turns out to be as terrible as they fear.

Arthur and his friends imagine Miss Ratburn as a baby in a crib doing calculus while her brother bothers her to spell the word "antediluvian". Then they imagine the two of them as eight-year-olds, eating nails for breakfast (based on Prunella's myths about Mr. Ratburn's dietary habits).

The eight-year-old Miss Ratburn says she likes her nails without milk, and screws are her favorite. Arthur and his friends then imagine Miss Ratburn and her brother in college; he teases her that he notified one of her professors of a mistake she made on a final paper, and her grade will be lowered accordingly.

Miss Ratburn gets back at her brother with the news that she proved the star he discovered was nothing but gas, and his name will be taken off the Honor Roll. In response, young Mr. Ratburn vows that someday he will show her, by becoming the toughest teacher in the universe. Miss Ratburn disagrees, vowing that she will be even tougher.

The next day, Miss Ratburn arrives, but is surprisingly sweet and cheerful. Rather than having the students do complicated math as Mr. Ratburn does, she practices the multiplication tables with the class, only doing the 1x table. Surprised by how easy her class is, the kids gladly play along.

Miss Ratburn also puts on a puppet show, teaches the names of the four seasons, quizzes the students on basic color concepts, and has them recite simple words and phrases to match with pictures.

The class enjoys the unusually easy workday at first, but are soon bored by the simplicity of the assignments. Brain speaks up about it, so Miss Ratburn tries to make things more difficult...by doing the 2x table. The kids are relieved when class finally ends, and Brain runs out in a panic. At the treehouse, the kids realize they actually miss Mr. Ratburn.

The next morning, the class waits in dread for another day with Miss Ratburn, knowing they will be bored again. However, Mr. Haney announces that Miss Ratburn will not be back today, because Mr. Ratburn has returned. The class enthusiastically welcomes him, and he immediately gets back to work.

Seeing Mr. Ratburn's return, a couple of the kids watching in Miss Sweetwater's room say to each other that they feel bad for Arthur's class. Back in Mr. Ratburn's room, however, Arthur says he feels sorry for the students of Miss Sweetwater, who doesn't present much more of a challenge than Miss Ratburn. Buster makes a remark about how tough their work is, but the boys are happy to be challenged again.
