Maggie Simpson
Maggie's first word spoken in the normal television show of the series happened in "Lisa's First Word", when she was voiced by Elizabeth Taylor and says, "Daddy" in an empty room. Elizabeth Taylor as Maggie was later named the 13th greatest guest spot in the history of the show.  James Earl Jones, who voiced Maggie in "Treehouse of Horror V" was in seventh place.  She would later have small sentences in "Treehouse of Horror IX", voiced by Harry Shearer, who used his Kang voice.  Her squeaks and occasional speaking parts are regularly done by Nancy Cartwright or Yeardley Smith. Jodie Foster voiced the Howard Roark-inspired Maggie in the Season 20 episode "Four Great Women and a Manicure".
