Arthur Takes a Stand

Official synopsis
Arthur thinks Mrs. MacGrady is being treated unfairly and seeks guidance from Congressman John Lewis.

Plot

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".
