Back to the Pilot from Best Family Guy Episodes

"Back to the Pilot" is the fifth episode of the tenth season of the animated comedy series Family Guy. It originally aired on Fox in the United States on November 13, 2011. In "Back to the Pilot", two of the show's main characters, baby genius Stewie and anthropomorphic dog Brian, both voiced by series creator Seth MacFarlane, use a time machine to travel back in time to the first episode of the series, "Death Has a Shadow". Trouble ensues however, when Brian tells his former self about the September 11 attacks, causing the present to be dramatically changed, and ultimately resulting in a second civil war. The two must then prevent themselves from going back to the past in the first place, but soon realize that it will be much more difficult than they had originally thought.
