"Road to the Multiverse" is the first episode of the eighth season of the animated comedy series "Family Guy".
 This and most of the Season 8 episodes were produced for season 7.
 Directed by Greg Colton and written by Wellesley Wild, the episode originally aired on Fox in the United States on September 27, 2009, along with the series premiere of "The Cleveland Show".
 In "Road to the Multiverse", two of the show's main characters, baby genius Stewie and anthropomorphic dog Brian, both voiced by series creator Seth MacFarlane, use an "out-of-this-world" remote control to travel through a series of various parallel universes.
 They eventually end up in a world where dogs rule and humans obey.
 Brian becomes reluctant to return to his own universe, and he ultimately ends up breaking the remote, much to the dismay of Stewie, who soon seeks a replacement.
 The "Road to" episodes which have aired throughout various seasons of "Family Guy" were inspired by the "Road to ..." comedy films starring Bing Crosby, Bob Hope and Dorothy Lamour, though this episode was not originally conceived as a "Road to" show.

 In the episode, Brian offers to help an African-American woman change the name of James Woods Regional High School to Martin Luther King Jr., but his friendship with Peter becomes strained when Peter — who objects to the idea — recruits actor James Woods to sabotage the idea.
 James Woods would later return for revenge in the season 6 episode "Back to the Woods", and again for "Brian Griffin's House of Payne" and would eventually be killed off in the season 9 premiere episode "And Then There Were Fewer", but is later revealed to have survived his death in the season 10 episode "".
