I really did not like "So Funny I Forgot To Laugh". Remember, Sue Ellen stood up to Binky Barnes in "Bully for Binky" way back in season 1, and she also wasn't afraid of anything until "What Scared Sue Ellen?" in season 3. This new episode has her really out of character. I would have liked to see Fern being bullied, rather than Sue Ellen. Or better yet, bring back Jenna and have her get bullied. 

Also, why was Arthur the bully? Why not a Tough Customer? Maybe it was in effort to show that ANYONE can be a bully, and not realize it at first.
