Yep, Marcia Wallace was the crazy receptionist on "The Bob Newhart Show". In fact, by 1972 Marcia Wallace had lost a lot of weight by the time she appeared with Bob on his show.
It was my mom that told me about Marcia's life long battle with being heavy. Like a lot of actors/comedians, Marcia had to overcome a not so happy childhood. At first she made people laugh with "fat jokes" as a stand up comedian, but as she gained control over her weight she found that she still had the magic of making people laugh.
Her voice work as Edna was priceless! You guys got to hear Marcia at the top of her Game. I'm with all of you in saying that I will truly miss her.
REST IN PEACE MARCIA WALLACE
