The Simpsons paid tribute to Marcia Wallace – the voice behind teacher Mrs Krabappel – who died on Oct 25.
In the show’s opening credits, in the episode that aired Sunday night in the US, a sad looking Bart chalks, “We’ll really miss you Mrs K,” on the blackboard.
The 70-year-old actress died on Oct 25 at her home in Los Angeles of complications from pneumonia.
“I was tremendously saddened to learn this morning of the passing of the brilliant and gracious Marcia Wallace. She was beloved by all at The Simpsons and we intend to retire her irreplaceable character,” said executive producer Al Jean in a statement.
Mrs Krabappel is famous for her scathing laugh and appeared in 178 episodes of the long-running TV shows.
