Stewart "Stewie" Gilligan Griffin is the flamboyant and eccentric one year old infant of Peter and Lois Griffin. Stewie, equipped with his teddy bear, Rupert and his laser gun, has, on several occasions, almost single handedly taken over the world and he seems to be obsessed with world domination and matricide. In The Real Live Griffins, he was played by Ashley Olsen. Although he has remained physically one year old since "Chitty Chitty Death Bang", mentally he seems much older, even proclaiming in "I Never Met the Dead Man" to be shooting on a fifth grade level.
