Margaret Simpson ("Maggie") is the youngest daughter in
The Simpsons household, eternally a baby. Her claim to fame is sucking on her
pacifier[?] and falling down frequently as she struggles to walk. She has spoken only one word in the normal continuity of the series--"Daddy" (voiced by
Elizabeth Taylor)--and no one heard it.
During one of the Halloween episodes, she was an Alien/Human crossbread and had the voice of James Earl Jones.
