Stewart "Stewie" Gilligan Griffin is the flamboyant and eccentric one year old infant of Peter and Lois Griffin on the TV show, Family Guy.
Steve and Roger watch a DVD of Stewie and his best friend, Brian Griffin taking a plane trip to Miami to hatch a scheme at Florida State University in "The Worst Stan". Steve and Roger question the reality of a baby and a dog flying and are smugly satisfied that a boy and an alien in a wig taking a bus trip are perfectly normal.
Stewie is voiced by Seth MacFarlane doing an impression of actor Rex Harrison.
