They'll miss that laugh. When actress Marcia Wallace passed away a few months ago, it left The Simpsonsshowrunners saddened and tasked with sending off Mrs. Krabappel. This is how they chose to handle it in last night's episode. Without giving away too much, it features Ned Flanders honoring his late second wife. Also, Flanders married Mrs. Krabappel? Seems like a lot has changed on The Simpsons in the years since I've stopped watching. Now I'd get my ass handed to me on Simpsons Trivial Pursuit.
