The Simpsons include Edna Krabappel in Christmas credits Bart Simpson's schoolteacher Edna Krabappel had a fleeting cameo role in The Simpsons' Christmas episode when it aired in the US on Sunday. In the episode's elaborate opening credits, Edna Krabappel could be seen with her favourite coffee cup and a pair of wings and a halo. The actress who voiced her, Marcia Wallace, died in October aged 70, and The Simpsons paid tribute to her character then, with Bart writing on the chalkboard: "We'll really miss you, Mrs. K." The angelic Edna was joined by another late member of The Simpsons' creative family, writer Don Payne. A cartoon likeness of Payne, who died in March from bone cancer aged 48, was shown wearing a white suit, wings and a halo. Al Jean, The Simpsons executive producer, told E! News: "We wanted to do a tribute to two terrific people, Marcia and Don. The episode was, sadly, Don's last.
