Arthur Takes a Stand

Official synopsis
Arthur thinks that Mrs. MacGrady is being treated in an unfair way and seeks guidance from Congressman John Lewis.

Plot
Sue Ellen Armstrong informs Arthur (who doesn't know who John Lewis is) that he was "a really important civil rights leader from the 1960s and challenged the lack of equal rights for black Americans" while Ladonna Compson elaborates he "helped guarantee that everyone could vote" and that he "was one of Dr. Martin Luther King Jr.'s most important allies".

Episode Connections

 * When Ms. Tingley is speaking on the loudspeaker, George is wearing the same H.M. hat from "The Hallway Minotaur".
 * Arthur refers to Ms. Tingley as "the principal" since she has assumed the role of Lakewood Elementary's temporary principal while Mr. Haney is in Tanzania. This is the first episode since "The Hallway Minotaur" to show her in this new position.
 * The episode's title sounds similar to the twelfth season episode, "Mei Lin Takes a Stand".

Production notes

 * Some broadcasts changed some of Ladonna's dialogue. In the original, she says, "He was one of Dr. Martin Luther King Jr.'s most important allies." In the alternate cut, she says, "He also wrote this really cool graphic novel called March. I have it at home."
