Desk Wars

Desk Wars is an episode of Arthur. This episode breaks the fourth wall, when Francine claims to Arthur, "How come you always get to introduce the show?".

Synopsis
It is a warm day in Mr. Ratburn's class. Through a series of unfortunate events (no copy of the book title intended), pandemonium breaks out in Mr. Ratburn's class.

Trivia

 * In this episode, Mr. Ratburn received a call from his sister Miss Ratburn, and told the class he became an uncle, which meant she had given birth to a child; although in her exclusive appearance in Arthur's Substitute Teacher Trouble from the first season, she was single and was not pregnant, nor did it reveal whether or not she had children.
