Blue Harvest - S6-E1
Trivia: In the episode "Blue Harvest Part 1," Peter narrates a telling of Star Wars from his point of view. When Chris is walking through the bar, we see Bender from Futurama, Coach John McGuirk from "Home Movies," The Evil Monkey from Family Guy and The Alien from American Dad sitting in the background talking to people.
Blue Harvest - S6-E1
Continuity mistake: After Vader (Stewie) kills Obi-Wan, Luke yells out and then the shot shows storm troopers firing at him with Vader in the background. Vader's lightsaber is blue, when it should be red. It is red in the previous and next shots. (00:34:00)

Other mistake: In the scene where the Millennium Falcon has just left the death star after Obi-Wan has been killed, there are two shots of the ship flying away through space. In the second shot, the cockpit is missing. (00:33:35)
