Given that the main characters in Stargate SG-1 are modern-day Earthlings, Shout-Outs are to be expected.
- There are a whole lot of Simpsons references throughout the series, since it is O'Neill's favorite show. Commentary on the DV Ds reveals that these were included because it is Richard Dean Anderson's favorite show in real life. Which culminated in Dan Castellaneta's appearance in the episode "Citizen Joe" (as well as Anderson's appearance as himself in the Simpsons episode "Kiss Kiss, Bang Bangalore", attending a Stargate convention).
- Carter's "It took fifteen years and three supercomputers to MacGyver a way to open the gate" line, improvised by Tapping.
- At the start of first season episode "Politics," Jack dismisses Daniel's story of an alternate universe with "And you were there, and you were there, and there's no place like home."
- When Senator Kinsey laughs off the Goa'uld threat as no match for the U.S. military, Daniel mockingly says "Oh sure, we'll just upload a computer virus into their mothership."
- Used with glee in "1969", with plenty of Star Wars references, up to and including O'Neill introducing himself as "Luke Skywalker". (And James T. Kirk.)
- Season Three episode "Shades of Grey." "Hello, Newman."
- In "Tangent", Daniel claims to be "The Great and Powerful Oz", which is only one of numerous references to The Wizard of Oz throughout the show. Jonathan Glassner mentioned on the DVD featurettes for season 3 that it became a Running Gag between him and another writer to see how many Wizard of Oz references they could fit into the show.
- Later, when Daniel and Sam tell Jacob Carter that they were hoping he could "beam" Teal'c and O'Neill out of their out-of-control craft, he incredulously asks if they think he is Scotty.
- In the episode "2010" Carter is involved with a plan to turn Jupiter into a star, referencing Arthur C. Clarke's book 2010: Odyssey Two. In the sequel "2001" Clarke and his novel is explicitly mentioned.
- In "Wormhole X-Treme!", one of the aliens infiltrated the studio using the alias "Steve Austin."
- "The Other Guys" contains many references to Star Trek, both overt and subtle. The characters of Coombs and Felger discuss the series, with Coombs a fan and Felger very condescending, and Khonsu has a bat'leth, a Klingon weapon, on the wall behind his throne. Khonsu is also dressed all in red and is killed soon after Coombs mentions that they are as likely to die as if they were wearing red shirts. Funnier since Coombs plays a Star Trek: Enterprise regular, Dr. Phlox. Funnier still, considering how many Star Trek regulars had guest spots on Stargate.
- O'Neill wants to call the Prometheus the Enterprise.
- A season seven episode is actually titled "Enemy Mine."
- In "Avenger 2.0", Felger prominently packs a roll of duct tape in his pack when he plans to go off-world with Carter. DVD audio commentary confirmed that this was reference to The Red Green Show, which starred Felger's actor.
- In "Zero Hour", when the alien plant grows out of control Dr. Lee jokes that at least it has not eaten anybody yet; O'Neill's only response is to thank "Seymour".
- Daniel calls himself "Hans Olo" in "Prometheus Unbound".
- When Mitchell is captured by someone in face-concealing black armor who beats him up. Then, when he's tied down, removes her helmet, revealing Claudia Black — a definite shout-out to the first reveal of Aeryn Sun in Farscape.
- Season eight episode Avatar has Carter remark that Teal'c played Doom when entering a simulator that is very similar to it. He responds saying he played Def Jam Vendetta. Teal'c's actor did voice work for the latter.
- In the season 9 episode "Ex Deus Machina", one of the persons of interest is the CEO of the Stark Constortium.
- In season 9's "The Scourge", Mitchell motivates a tired bureaucrat to keep marching by making up "treeferrets", a dangerous arboreal creature that can separate a man's head from his shoulders. In the Honorverse, treecats are dangerous arboreal creatures that can separate a man's head from his shoulders, and are described as actually looking like ferrets, not cats.
- Later, when Mitchell and Teal'c discuss what they are going to watch on movie night Teal'c explains that he was considering Old School. At the end of the episode, after defeating the horde of alien insects, Mitchell explains that they are instead going to watch Starship Troopers.
- Vala says she became pregnant without having sex any time around when conception must have been. As she is unfamiliar with Earth culture she asks the team if they have ever heard of anything like this. The viewer and some members of the team obviously think of Jesus, but Teal'c speaks up quickest with "Darth Vader". Vala immediately asks Teal'c how that turned out, and nobody seems willing to answer. A moment later, Mitchell says he was thinking of King Arthur.
- When Vala tells SG-1 about an unpleasant man named Seevis, Mitchell summarizes with "Seevis is a butt-head".
- In "Morpheus", Vala "studies" for her upcoming psychiatric review by researching the Earth internet. One of the questions she prepares for is from the Voight-Kampff test from Blade Runner, which is administered to see if the subject is a replicant.
Vala: "You are in a desert. You see a tortoise that's lying on his back in the hot sun. You recognise his plight, but do nothing to help. Why?" ... Hmn. Why...? Ah: "Because... you are also... a tortoise..."
- The episode "200" revolves around the production of a Wormhole X-Treme! movie, which was being produced even though the show had been cancelled after airing only three episodes. DVD commentary confirmed that this was a reference to Firefly and Serenity. "200" is a hurricane of shout-outs, with entire segments dedicated to Star Trek, The Wizard of Oz and Farscape, as well as a short Gilligan's Island reference.
One sequence was an abridged mashup of elements of the movie and pilot episode, done in the style of Team America: World Police (or the show Team America parodied, Thunderbirds), complete with puppets by the Chiodo Brothers.
- This early line from "Fail Safe":
- After Jack recovers from being Touched in "The Broca Divide", he has this exchange with Teal'c when he's trying to convince him to let him out of the isolation cell:
- In "Chain Reaction", Jack and Maybourne introduce themselves to Senator Kinsey's wife as Starsky and Hutch.
- "Avalon, Part 2" has Cameron say that the Ancients came to our galaxy a long time ago from far, far away.
- "Origin" has Vala remark that she doesn't think "enlightenment" means what the Priors think it means. Funnily enough the next episode, "The Ties That Bind", features a guest appearance by Wallace Shawn, who played Vizzini in the movie.
- In "Morpheus" Cameron asks if Sir Gawain was one of the Knights Who Say "Ni." (He's actually close: Gawain appeared in the movie, albeit as Monster Munch.)
- "Bad Guys" is Die Hard in a museum, except due to a misunderstanding, SG-1 plays the role of the bad guys (hence the name). Mitchell even refers to the bumbling security guard as "McClane".
- In the opening of "Zero Hour", Sgt. "Chevron Guy" Harriman is constantly anticipating O'Neill's needs and finishing his sentences. A small guy in glasses who appears more competent than his somewhat-clueless CO, and who's first name is Walter?
- In the Season 1 episode 10 "Fire and Water", Teal'c finds a game of Hounds and Jackals among Daniel's effects. He mentions that they "belonged to a Pharaoh's daughter" probably a reference to the scene in The Ten Commandments where Pharaoh Sethi's daughter Nefretiri plays the game with him.
- In "Upgrades", the Atanik armbands bear the inscription "With great power comes great responsibility."
- In "Seth", after Carter kills Setesh, O'Neill delivers the following Bond One-Liner:
O'Neill: Hail to Dorothy!
