The Simpsons/Maggie

Margaret Simpson ("Maggie") is the youngest daughter in The Simpsons household, eternally a baby. Her claim to fame is sucking on her pacifier. 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 Halloween episode, she became an Alien and had the voice of [James Earl Jones]?.
