"The Simpsons" paid tribute to Marcia Wallace Sunday night with a sweet sendoff for the actress who provided the voice of Bart's teacher Edna Krabappel for more than 20 years.
Wallace, who also played wisecracking receptionist Carol Kester
on the 1970s sitcom "The Bob Newhart Show," died Oct. 25 of complications of pneumonia. She was 70.

"The Simpsons" said goodbye to Wallace Sunday night in the opening credits of the long-running animated sitcom. The classic chalkboard scene, in which Bart is seen writing the same sentence over and over again in detention, was rejiggered to show him writing just one sentence: "We'll really miss you Mrs. K."
"I was tremendously saddened to learn of the passing of the brilliant and gracious Marcia Wallace," "Simpsons" executive producer Al Jean said in a statement. "She was beloved by all at 'The Simpsons' and we intend to retire her irreplaceable character."
Other voice actors from the series mourned the loss of Wallace on Twitter.
Wallace completed her voice work on "The Simpsons" before her death so her character will continue to be featured on the show. Jean said the retirement of Mrs. Krabappel will come later this season or early on in the show's 26th season.
The loss of Mrs. Krabappel is not what execs meant when they announced last month that a main character would be killed off this season, Jean said.
"Earlier we had discussed a potential storyline in which a character passed away. This was not Marcia's Edna Krabappel," he said. "Marcia's passing is unrelated and again, a terrible loss for all who had the pleasure of knowing her."
"The Simpsons" airs Sundays at 8 p.m. EST on Fox.
