“The Simpsons” paid tribute to the late Marcia Wallace in its final episode for Edna Krabappel, Springfield’s long-standing elementary school teacher. Wallace voiced the character in more than 100 episodes of the show.
The episode revolved around the comeback of villain Sideshow Bob, but the touching final scene portrayed Ned Flanders daydreaming about Edna. In the dream, Ned dances with Edna and she proceeds to laugh. Ned then awakens and says, “I sure do miss that laugh.”
The touching moment is then abruptly disrupted by Nelson’s signature cackle, but he then says, “I miss her, too.”
