(UPI) -- For 24 years, Marcia Wallace was the voice of fourth-grade teacher Edna Krabappel on The Simpsons.
Wallace died last week, and to honor her, Fox and producers for the longtime animated show plan to reschedule their Sunday lineup to air one of the most memorable episodes featuring her character.
In "Bart the Lover," the 16th episode of Season 3, Bart learns his teacher, Edna Krabappel, has posted a personal ad. He starts writing fake love letters as a prank, and sets her up on a fake date. After she sits alone at a restaurant for hours, Bart begins to regret playing the prank. It won Wallace an Emmy in 1992.
The episode will air at 7:30 p.m., leading into a new episode, "4 Regrettings and A Funeral." The 8-p.m. half-hour will end with a tribute card in Wallace's honor.
"I was tremendously saddened to learn this morning of the passing of the brilliant and gracious Marcia Wallace," said producer Al Jean. "She was beloved by all at The Simpsons and we intend to retire her irreplaceable character."
Wallace was 70 when she died. She was a 28-year survivor of breast cancer. She became a star playing Carol Kester on The Bob Newhart Show from 1972-1978.
