19. Maggie Is Voiced By... Matt Groening?

Unlike most members of the family who have been voiced unanimously by the same actors across all twenty-four seasons, Maggie has been played by just about anyone willing.
Most of the key female voice actors have had a go at the baby, delivering lines in dream sequences or creating her babbling, but numerous guest stars have been brought in for special moments; Elizabeth Taylor delivered her actual first word, Jodie Foster rallied babies yet another daycare escape and even James Earl Jones did his part in a Treehouse Of Horror Episode.
But the most surprising person to voice Maggie is creator Matt Groening; hes the source of the ever present pacifier sucking.
