Marcia is currently giving voice to Ms. Edna Krabappel, Springfield's Elementary's beleaguered teacher on The Simpsons. She has also finished her first book entitled Don't Look Back, We're Not Going That Way. The title is a quote from her larger than life father. Of course, he also used to say "If I don't see you again the mule is yours," so not everything he said was deep. The book is subtitled How I Overcame a Rocky Childhood, a Nervous Breakdown, Breast Cancer, Widowhood, Fat, Fire & Menopausal Motherhood and Still Managed to Count My Lucky Chickens.
