The animators of The Simpsons paid tribute to late cast regular Marcia Wallace at the close of Sunday night's show.
The actress, who voiced Bart Simpson's fourth grade teacher Edna Krabappel, died of complications from pneumonia in October.
The character was immediately retired from the show out of respect, but Mrs Krabappel made a return to The Simpsons at the weekend in a dream sequence.
The cartoon teacher appeared dancing and laughing with her husband Ned Flanders, but it quickly became clear he was just dreaming after falling asleep in his living room. After he wakes up, he says "I sure do miss that laugh," while glancing at a picture of Krabappel next to a another photo of his dead wife Maude. Just then, school bully Nelson Muntz appears in his window, laughs and says "I miss her too."
