RIP Marcia Wallace/Mrs Krabappel

From the LVRJ: Marcia Wallace, the voice of Edna Krabappel on “The Simpsons,” has died.
“Simpsons” executive producer Al Jean said in a statement Saturday that her death is a terrible loss. He says Wallace’s “irreplaceable character,” the fourth-grade teacher who has to deal with Bart Simpson’s constant antics, would be retired from the show.
The longtime TV actress’ credits ranged from playing a wise-cracking receptionist on “The Bob Newhart Show” to appearances on Candice Bergen’s “Murphy Brown.”  http://www.reviewjournal.com/entertainment/tv/marcia-wallace-dies-voice-simpsons-krabappel
I remember her most for her role on the Bob Newhart show as the wise cracking floor secretary, Carol. 
RIP to Marcia and prayers to her family and friend.
