Family Guy was already Reference Overdosed, but many of those gags still required permission to use other intellectual property on a commercial work. Fortunately the people at Lucasfilm were nice enough to okay just about any reference to Star Wars, so Seth MacFarlane decided to take that Up to Eleven, and recreate the whole original trilogy.Thus the episode "Blue Harvest"*
named for the fake title for Return of the Jedi to get around locations overcharging them to shoot there
recreated A New Hope, and was a commercial and critical success. Then came "Something Something Something Dark Side"*
Based off of Admiral Ackbar's Memetic Mutation line, although it was formerly going to be titled "I Got A Bad Feeling About This" which was based on the Running Gag a Star Wars character would say in a dangerous situation
And it's also not the first time Green played someone who got into arguments with his father, either. Green also played Scott Evil from Austin Powers, and anyone who has seen the first two movies will see that Scott and Dr. Evil do not have a good relationship.
The Jedi special makes Green into a Butt Monkey, which acts as Chris/Luke's Berserk Button. After the story, Chris asks Peter what he has against Green, and makes some comments about MacFarlane's talent instead; Brian, Stewie, and Peter all defend MacFarlane, and Meg (Mila Kunis), Lois (Alex Borstein), and Chris (Green) all say he's a dick.
Peter also mentions Without A Paddle which Seth Green starred in.
When Jabba is about to shove Luke into the Sarlacc pit (played by Meg), his Huttese is clearly "Miiiilllllllaaaa Kuuunisssssss"
Big Blackout: Used in the frame story to justify Peter Griffin telling the Star Wars stories. True to form, once his reciting the story ends, the power comes back on.
Breaking In Old Habits: Chris/Luke Skywalker gets a replacement hand. The doctor tells him "I'd practice on a hot dog first."
Brought Home The Wrong Kid: In Blue Harvest, Peter mentions that he and Lois got halfway home with the afterbirth before going back to the hospital and swapping it out for Meg.
Cold Opening: Each installment begins with the Griffin family watching various television programs before the lights go out.
Creator Breakdown: It's A Trap opens with the word crawl complaining they were sick of doing the Star Wars spoofs. The DVD Commentary makes it clear that no, it is not a joke.
This is lampshaded by Stewie (as Vader) at the beginning of the third episode when Roger appears. Stewie is surprised and says something to the effect of "It's you [Roger]? Are we really out of our own characters? We have to use you?"
In the background in the Mos Eisley cantina, we see Coach McGuirk from Home Movies, Roger from American Dad, and Bender from Futurama.
Gangsta Style: Cleveland/R2 shooting a TIE Fighter that way.
"Yeah-heah! That's how we do it in my neighborhood, Bitch!"
History Marches On: The DVD release of It's a Trap features a throwaway gag of Osama bin Laden popping up in the middle of the Tatooine desert to announce "Still alive!" Less than three weeks before the television premiere, this ceased to be so. The sequence was edited out of the televised version.
Imperial Stormtrooper Marksmanship Academy : In "Blue Harvest", when the group are fleeing the Death Star, no one is ever hit, even when Han (Peter) and Chewie (Brian) spend about 25 seconds standing at the doorway trying to get a couch through the door.
Money, Dear Boy: The opening of the third episode jokes that the creators only created the last episode because the first two made enough money that that they were forced into doing so.
Princess Leia: Why, you stuck-up, half-witted, scruffy-looking nerf herder! Han Solo: Who's scruffy-looking?
And the scene in Something, Something, Something Dark Side:
Lois: Why, you stuck-up, half-witted, scruffy-looking nerf herder! Peter: *hits Lois* You can't use that word! Only we can use that word!
Noodle Incident: Several, with three occurring in "Blue Harvest," both involving Obi-Wan/Old Man Herbert:
The first was in the scene where Obi Wan/Old Man Herbert receives the SOS signal from Princess Leia/Lois Griffin, where the latter mentions that (Obi-Wan) owes her for keeping several Aldreaanian children silent for obviously sexual reasons, but the only thing we got out of her was "Joey Lawrence Haircut" due to Obi-Wan/Old Man Herbert fast forwarding through the details due to Luke Skywalker/Chris Griffin being nearby.
The second was when Darth Vader/Stewie Griffin encounters and duels Obi-Wan/Old Man Herbert, where it is mentioned that Vader/Stewie had placed a restraining order on Obi-Wan/Herbert with a distance limit of 50 yards for reasons unspecified.
Obi-Wan/Herbert also briefly mentioned something about sock puppets when telling Luke/Chris to use the Force to place the proton torpedos into the Death Star's thermal exhaust port that he entertained Luke/Chris with as a kid, but elaborates no further other than warning him not to mention the sock puppet shows because it would get him into trouble if he mentioned them.
The DVD commentary for "It's a Trap" mentions that Fisher was initially reluctant to voice for the special, but relented when she came to the conclusion that she'd be playing Angela and not Leia.
Spared by the Adaptation: Biggs, mostly because he wasn't able to take off for the battle due to an unspecified injury that resulted in him being confined to a wheelchair.
Also done at the end of It's a Trap! towards the series creator Seth McFarlane, by Chris, Lois, and Meg as revenge for Peter Griffin constantly ripping down Robot Chicken.
Written-In Infirmity: In-Universe example with Blue Harvest. Because Biggs Darklighter was portrayed by Joe Swanson, Biggs Darklighter was confined to a wheelchair. He explains that he got an injury from an accident regarding his repairing a Y-Wing that left him paralyzed.
