YMMV / Arthur S16 E10 - "So Funny I Forgot to Laugh" / "The Best Day Ever"

• Bile Fascination: The reason why many people watch this episode is because of its negative reception among the Periphery Demographic due to Arthur being uncharacteristically mean towards Sue Ellen.
• Broken Base: The episode is divisive among the fandom, since while pretty much everyone hates it, there's debate over whether Arthur was truly being a bully and thus the episode is bad because he was out of character, or whether Sue Ellen really did overreact and she was the one being out of character for being so offended by the jokes, and Arthur's friends were the ones being mean by giving him the Silent Treatment and calling him a bully.
• Don't Shoot the Message: The Aesop against bullying, especially the message of how teasing can go too far and that a "Just Joking" Justification is not an appropriate apology, is a good lesson for the show to have. However, the reason why this episode is widely disliked is due to how there were several characters going against their usual personalities in order to deliver this message, which makes the lesson come off as awkward.
• Fanon Discontinuity: We wish you good luck finding anyone who likes this episode, especially for its derailment of Arthur into a bully who mocks Sue Ellen's sweater.
• Never Live It Down: Many fans have not forgiven Arthur for bullying Sue Ellen over her sweater despite him normally being a genuinely Nice Guy as well as the fact that showed remorse and apologized at the end.
• Unintentionally Unsympathetic: Arthur's friends giving him the Silent Treatment and calling him a "bully" was meant to be him getting karma for taking his teasing of Sue Ellen too far, but some of the viewers thought that this was meaner than Arthur's dog jokes, especially with Francine and Muffy, who were seen by some as hypocrites since they're usually mouthier than Arthur.
