* SpaceFighter: Notable in that the [[ScaryDogmaticAliens villains]] have space fighters from the very start, but the good guys have to develop theirs slowly over several seasons. As with all Goa'uld technology, their Death Gliders are [[CoolButInefficient more impressive than practical]]. The Ori crusaders have space fighters too, which easily curbstomp Death Gliders.

* SpaceColdWar:
** The Asgard and the Goa'uld prior to the series. Thor mentions in "Fair Game" that the only thing stopping the Asgard from wiping out the Goa'uld on general principles is the fact that they can't spare the ships from their war with the Replicators. The solution ended up being a massive bluff: the Goa'uld don't mess with Asgard protected planets for fear that the Asgard will wipe them out; otherwise they have basically free run of the Milky Way.
** Langara prior to "Homecoming" was engaged in a cold war between the three dominant superpowers. Two of those superpowers pull an EnemyMine in "Shadow Play" and gang up on the third, which launches a pre-emptive strike with a naquadria bomb. This scares the hell out of all concerned and puts MAD into play long enough for Anubis to show up and render the question moot. The superpowers form a United Nations-esque ruling council shortly thereafter.
** In "Icon", the cold war on Tegalus between the Rand Protectorate and Caledonian Federation is disrupted by SG-1's arrival, which allows a religious extremist faction to rise up in Rand, eventually overthrowing the government and starting a war which reduces most of the continent to rubble. The SGC helps the Rand loyalists regain control, but the international tensions remain into season nine's "Ethon", when the Ori give the Rands a KillSat.

As with all Goa'uld technology, their Death Gliders are [[CoolButInefficient more impressive than practical]].practical]]; a single F-302 is worth at least three gliders.

moved Shout Out section to new Shout Out subpage


* ShoutOut: Ohhh, so many.
** There are a whole lot of ''[[TheSimpsons Simpsons]]'' references throughout the series, since it is O'Neill's favorite show. Commentary on the DVD's reveals that these were included because it is Richard Dean Anderson's favorite show in real life.
** Carter's "It took fifteen years and three supercomputers to [=MacGyver=] a way to open the gate" line, improvised by Tapping.
** When Senator Kinsey laughs off the Goa'uld threat as no match for the U.S. military, Daniel mockingly says "What do you suggest we do, [[IndependenceDay upload a virus to their mothership?]]"
** Used with glee in "1969", with plenty of ''StarWars'' references, up to and including O'Neill introducing himself as "Luke Skywalker". (And [[StarTrek James T. Kirk]].)
** Season Three episode "Shades of Grey". "Hello, ''Newman''."
** The American submarine briefly mentioned in the episode "Small Victories" as being ready to destroy the Russian sub is named USS ''[[TheHuntForRedOctober Dallas]]''.
** In "Tangent", Daniel claims to be "The Great and Powerful Oz," which is only one of numerous references to ''Film/TheWizardOfOz'' throughout 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 [[StarTrekTheOriginalSeries Scotty]].
** In the episode "2010" Carter is involved with a plan to turn Jupiter into a star, referencing ArthurCClarke's book ''[[http://en.wikipedia.org/wiki/2010:_Odyssey_Two 2010: Odysey Two]]''. In the sequel "2001" [[LampshadeHanging Clarke and his novel is explicitly mentioned]].
** In "Wormhole X-Treme!" one of the aliens infiltrated the studio using the alias "[[SixMillionDollarMan Steve Austin]]."
** "The Other Guys" contains many references to ''StarTrek'', 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 [[RedShirt all in red]] and is killed soon after Coombs [[LampshadeHanging mentions that they are as likely to die as if they were wearing red shirts]].
** O'Neill wants to call the ''Prometheus'' the ''[[StarTrek Enterprise]]''.
** A season seven episode was actually titled "Film/EnemyMine".
** In "Avenger 2.0," Felger prominently packs a role of duct tape in his pack when he plans to go off-world with Carter. DVD audio commentary confirmed that this was reference to ''TheRedGreenShow'', 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 "[[LittleShopOfHorrors Seymour]]."
** Daniel called himself "Hans Olo" in "Prometheus Unbound".
** In the season nine episode "Ex Deus Machina", one of the persons of interest is the CEO of the [[IronMan Stark Constortium]].
** In season nine's "The Scourge," Mitchell motivates a tired bureaucrat to keep marching by making up "treeferrets," a dangerous arboreal creature that can separate a mans head from his shoulders. In the [[HonorHarrington Honorverse]], tree''cats'' are dangerous arboreal creatures that can separate a mans head from his shoulders, and are described as actually looking like ferrets, not cats. Later, when Mitchell and Teal'c [[CasualDangerDialogue 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 [[BugWar the horde of alien insects]], Mitchell explains that they are instead going to watch ''Film/StarshipTroopers''.
** 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 [[StarWars "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 KingArthur.
** 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 ''Film/BladeRunner'', which is administered to see if the subject is a replicant.
--> "'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 ''Series/{{Firefly}}'' and ''Film/{{Serenity}}''. "200" was a hurricane of [[ShoutOut Shout Outs]], with entire segments dedicated to ''StarTrek'', ''TheWizardOfOz'' and ''{{Series/Farscape}}'', as well as a short ''GilligansIsland'' reference.

* TakeThat:
** In "Politics" Daniel mocks the idea of regular US military forces taking on the Goa'uld by saying that sure, they will just [[IndependenceDay upload a virus into the mothership.]]
** In "Orpheus," Carter discusses seeing the movie ''{{Signs}}'' and is incredulous that the alien's weakness was water. When Daniel asked her why she even watches science fiction if she is just going to tear it apart, she mentions that she wants to see if they are getting it even close to right.
** In "The Scourge," Mitchell explains that the team is going to watch ''FIlm/StarshipTroopers'' for movie night since they spent the episode [[BugWar fighting a horde of alien insects]]. Teal'c, who had been planning to watch ''Old School'', asks if the movie is humorous, to which Mitchell responds "[[SoBadItsGood is it ever]]."
* TakingYouWithMe:
** The Alternate Samantha Carter of "There But For the Grace of God" lured in several Jaffa with the offer of valuable information for Apophis, then pulled out a grenade to take them out along with her.
** During the Battle of Antarctica in "Lost City", Hammond orders the ''Prometheus'' onto a collision course with Anubis' flagship, saying "We go, they go." [[spoiler:Subverted in that the weapons of the Ancient outpost get there first, and Hammond is only too happy to break off.]]
* TantrumThrowing: Cam gets frustrated and trashes his room in "Unending".
* TastesLikeFriendship: Daniel feeds random alien, random alien becomes his friend.
-->'''Daniel:''' [[ContinuityNod You know, it's funny]], [[{{Stargate}} I met my father-in-law like this...]]
* {{Technobabble}}: Mostly courtesy of Carter, [=McKay=], and a couple of others. O'Neill serves as a bit of a GreekChorus when this happens, either interrupting Carter to ask a simple "yes or no" question, or else to irritatedly inform her that he ''does'' know what photosynthesis and supernovas are, thank you.
* TeleporterAccident: "Solitude", "1969", "48 Hours".
* TeleportersAndTransporters: The Stargates and ring transport platforms inherited from the movie are the most common. The Asgard bring the ''StarTrek''-style "beams" into play.
* TeleportInterdiction: The iris is used to prevent anything unwanted from coming through the stargate.
* TemporaryLoveInterest: Several.
* TerminallyDependentSociety
* ThatManIsDead: At the conclusion of "Cor-ai," Hanno, who has spent the episode trying to get Teal'c executed for killing his father, allows him to go free after Teal'c had helped save him and his people from the Goa'uld. When Teal'c asks why, since he ''did'' kill his father, Hanno explains the he did not, as the Jaffa who did is dead.
* ThemeTuneCameo:
** Carter is humming the ''SG-1'' theme song in the elevator in "Chimera." [[WhatCouldHaveBeen She was originally going to hum the theme to]] ''MacGyver'', but neither she nor anybody else on set could remember how it went.
** During the wedding scene in "200," the organ is playing a combination of Mendelssohn's Wedding March (The "standard" wedding composition) and the shows theme.
* TheyCalledMeMad: Daniel Jackson and his grandfather, plus several different scientists encountered off-world who were studying their stargates. The plausibility of this varies, but is generally pretty strong if the Stargate is the only evidence of AncientAstronauts in the setting. In the case of Daniel and his grandfather, though, it is a bit of a ContrivedCoincidence to have two [[TheyCalledMeMad scientists called mad]] in the same family ''researching completely different alien artifacts''.
* TheyLookLikeUsNow
* ThroatLight: When a person is being tortured with the Goa'uld [[AgonyBeam cattle-prod device]], light shines out of their mouths and eyes. Richard Dean Anderson did not like this visual effect, and would close his eyes whenever Jack O'Neill was being tortured in order to keep it from being used
* TimeCompressionMontage: "Unending", the series finale, had one of these, set to Creedence Clearwater Revival's "Have You Ever Seen the Rain?"
* TimeForPlanB
** O'Neill likes to poke fun at this line.
-->'''Reynolds:''' Not much faith in Plan A?\\
'''O'Neill:''' Since when has Plan A ever worked?
** Another time:
-->'''O'Neill:''' It's time for Plan B.\\
'''Carter:''' We have a Plan B?\\
'''O'Neill:''' No, but it's time for one.
* TimeTravel: Multiple times, including alternate timelines.
* TimeTravelersAreSpies: In "1969".
* TomatoInTheMirror: in "Tin Man", where after visiting the ruins of a technologically advanced society, the team comes back through the Stargate only to discover that they are robot copies of the originals.
* TomboyishName: Samantha "Sam" Carter. In the pilot O'Neill [[SamusIsAGirl mistook her for a man]] when he was told that Sam Carter was their foremost expert on the stargate, and in a later episode when is asked what her name means, she responded that it means her dad wanted a boy.
* TookALevelInBadass: Daniel takes at least one level in {{Badass}} over the course of the series.
* TouchedByVorlons: Daniel, Anubis, Priors, Carter and O'Neill.
* TranquillizerDart: Osiris is twice shot by a tranquilizer dart tipped with a Goa'uld specific sedative.
* TranslationConvention: The episodes "Summit" and "Last Stand" are explicitly stated to be spoken in Goa'uld, but all the dialogue is in English for the convenience of the audience. Several other episodes have dialogue that is implied to be the same, particularly when aliens speak amongst themselves.
* TranslatorMicrobes: Though never mentioned in the show, [[AllThereInTheManual the novels based on the series]] reveal that the stargates somehow allow people from different planets to understand one another. The characters themselves do not understand how it works, nor why it works sometimes but not others, but it explains why almost all the [[AliensSpeakingEnglish aliens speak English]].
* TransplantedHumans: The majority of the inhabitants of the Milky Way are humans that the Goa'uld transplanted from Earth to serve as their labor force. The name used throughout SG-1 to refer to the people of Earth, "Tau'ri," translates as "those of the first world," since Earth is where everybody else originally came from.
* TrialByCombat: The Jaffa believe firmly in the concept of AsskickingEqualsAuthority; if a Jaffa believes that he is more worthy of leading than the Jaffa in charge he may challenge him to ritual combat for the position of leader.
* TricoloursWithRustingRockets: The Russians manage to acquire a Stargate and briefly run their own program. Later, Russian officers are part of the international program.
* TrueCompanions: SG-1, of course.
-->'''Samantha Carter:''' We were a team. No one else can even ''begin'' to understand what that means.
* TwoKeyedLock: Sometimes it is passwords, sometimes it is keys.
* TwoOfYourEarthMinutes: In "Beachhead," Mitchell explains to a Prior that their bomb will detonate in thirty "Earth minutes." When Daniel asks why he used the term, he explains that [[IAlwaysWantedToSayThat he always wanted to say that]].
* TyphoidMary: The Priors managed to sneak their plague onto the Earth by turning an SGC lieutenant into an asymptomatic carrier, passing through quarantine because he exhibited no signs of the disease before he began passing it on to civilians he encountered outside the base.
* TyrantTakesTheHelm: General Bauer in "Chain Reaction".
* UnflinchingWalk: Teal'c pulls this off in the episode "Talion".
-->'''Teal'c:''' I am leaving, you are about to explode.
* UngratefulBastard: SG-1 abandons Replicator Fifth to an eternal prison in a time bubble after Fifth betrayed his brethren to help them. This is heavily weighed before they follow their orders.
* UniquePilotTitleSequence: "Children of the Gods" imitates [[Film/{{Stargate}} the movie]] with a long pan over the mask of Ra. After that, they used cut-together clips from season 1, changing it only when the main cast changed. The DVD releases of seasons 4 and 5 use the "Children of the Gods" title sequence for some reason.
* TheUnsmile: In the first season, when Teal'c was still getting angry looks for being a Jaffa, Daniel explained that he was a friend and told him to smile. The resulting facial movement was...off.
* UnwantedRescue: In "The Other Guys," SG-1 allowed themselves to be captured on purpose in order to make contact with a Tok'ra that was undercover as a Goa'uld working for Anubis. They are somewhat perturbed when Coombs and Felger stow away aboard their prison ship in order to rescue them.
* UnresolvedSexualTension: Carter and O'Neill. WordOfGod states that just about the nanosecond Jack retired, he and Sam got it together and got it on. (Alternatively, [[WordOfGod Word Of A Different God]] states that they got together after "Threads" and have merely kept the relationship quiet ever since.) A deleted scene from the ''StargateAtlantis'' episode "Trio" also pretty much confirms that it finally got resolved.
** This causes the pair to be mistaken for brainwashed assassins in "Divide and Conquer", when a Tok'ra LieDetector gets a false positive because they [[spoiler:do not admit the real reason he would not leave her behind on the previous mission.]]
** The writers play with this hilariously in "Window of Opportunity". During one timeline cycle, since neither Carter nor, more importantly, General Hammond, will remember it after the timeline resets, O'Neill resigns his commission so he can finally kiss Carter.
* {{Unobtainium}}:
** The heavy metal naquadah, which is the material the stargate is composed of, does not naturally exist within the Solar System and is heavily involved in Goa'uld technology. Its nonexistence in the Solar System is a minor plot point in "Fail Safe". [[spoiler:Carter realizes that the asteroid they are trying to stop from hitting Earth has a core of naquadah, leading her to the conclusion that it was imported by the Goa'uld to circumvent the Protected Planets Treaty with a manufactured natural disaster.]] Naquadah can be converted to naquadria, a more powerful but unstable variant, when it is exposed to certain radiation.
** Trinium is a silvery metal that is very light and about a hundred times stronger than steel. The Tau'ri and Asgard use it in the hulls of ''Prometheus''-, ''Daedalus''-, and ''O'Neill''-class warships, while the Tollans combine it with other substances in several pieces of AppliedPhlebotinum (including the device that lets them walk through walls).
* UnusualEuphemism: "I told her that she should attempt procreation... with herself."
* UnusuallyUninterestingSight: The team often walks right into settlements with guns at the ready. Rarely does anyone seem to have any trouble with this, though it does pop up when the plot demands it.
* VictoriasSecretCompartment: Vala, who else?
* VillainBall: The Goa'uld, the Ori, the Lucian Alliance, even Tau'ri factions like the NID all juggled it from time to time. See examples in the trope page.
* VillainPedigree: The Ori and Replicator pull this on the Goa'uld.
* VoiceOfTheLegion
* WasntThatFun: Used in the ninth season; after the team has posed as drug dealers, been captured by drug dealers, got beaten up, captured by the Lucian Alliance, etc., they finally get back to Earth.
-->'''Mitchell:''' We have the best jobs in the world.\\
''({{beat}})''\\
'''Sam:''' I'm going to hit the showers. ''(exits)''\\
'''Daniel:''' I'm going to find the doctor. ''(exits)''\\
'''Teal'c:''' We are indeed suitably employed, Colonel Mitchell. ''(exits)''\\
'''Mitchell:''' Yeah, good day.
* WastelandElder: Several, usually one per [[AdventureTowns Adventure Town]]-- err, planet.
* TheWatson: Jonas Quinn joined the cast in season six from an alien planet, requiring him to be filled in on past SGC missions and esoteric parts of Earth history. This was particularly helpful since season six was the season where they began connecting and expanding on a lot of previously introduced continuity, primarily the concepts of Ascension, the Ancients and the greater society of the Goa'uld, so he could help bring new viewers up to speed.
* WeHaveForgottenThePhlebotinum: Several cases of needing something from another base, planet, or needing a bit of [=MacGyvering=] to make a new doohickey.
* WelcomeToTheLiberator: Jonas' arrival and departure from the team coincide perfectly with Daniel's departure and return.
* WeWillUseManualLaborInTheFuture: Justified for the the Goa'uld, who keep most of their human slaves in MedievalStasis to prevent rebellion. Generally averted by most of the other technologically advanced civilizations.
* WhamEpisode: In the episode "Heroes", the [[spoiler:death of Dr. Janet Fraiser]]. To add extra oomph, KilledOffForReal is played with in this episode, as two characters (including an RedShirt) receive potentially fatal wounds before it is revealed quite shockingly that [[spoiler:Janet]], whom the viewer does not even know got injured, is the one who actually died.
* WhatCouldHaveBeen: Apparently the third movie, entitled ''Stargate: Revolution'', would have featured Jack's return as the main character ''and'' it would have finally had the Stargate program going public. However it has been considered shelved for good at this point.
* WhatHappenedToTheMouse: So many incidents that the show gets its own folder on the WhatHappenedToTheMouse/LiveActionTV subpage.
* WhatTheHellHero:
** "Shades of Grey" when Jack steals technology from Tollana. [[spoiler: Subverted when revealed to be a BatmanGambit to draw out the real thieves from the NID.]]
** "Unnatural Selection;" where Jack [[IDidWhatIHadToDo made the hard call]] and was called on it by the team.
* WhatWeNowKnowToBeTrue: The Tollan have studied quantum physics... "among other misconceptions of elementary science".
* WhereItAllBegan: The season six finale, the first season finale [[UnCancelled that was originally planned to be the series finale]], takes place primarily on Abydos, the planet visited in [[Film/{{Stargate}} the movie]] and the very first planet that SG-1 went to when the show began.
* WhosOnFirst: The Goa'uld Yu resulted in some of this.
-->'''Dr. Jackson:''' And the last one is Lord Yu.\\
'''Dr. Weir:''' Yu?\\
'''Dr. Jackson:''' Don't. Every joke, every pun, done to death. Seriously.
* WhoWatchesTheWatchmen: Colonel Simmons of the NID explains the organization's mandate to O'Neill: Providing civilian oversight to top-secret military projects. Jack, however, wonders who oversees ''them''.
* WhoWritesThisCrap: When O'Neill summarizes his history to the memory-erased Martin, at the opening of act four, Martin comments that that is the worst Act Four Opener he has ever heard.
* WhyAmITicking: Cassandra
* WhyWontYouDie: Apophis had a habit of returning from supposed (And [[DeathIsCheap actual]]) deaths, much to the chagrin of SG-1.
--> '''O'Neill:''' ''(referring to Apophis)'' Somebody's gotta teach that guy how to die.
* {{Will}}: Colonel O'Neill has [[MauveShirt Sgt. Siler]] designated in his will as the recipient of his collection of ''Simpsons'' videos. Siler has the colonel in his will as well, but what is left to him is never revealed.
--> '''O'Neill''': *rescuing Siler* I expect to be put in your will for this!
--> '''Siler''': Already are, sir!
--> '''O'Neill''': Ok that's... weird.
* WillTheyOrWontThey: In several episodes, the writers play with romantic tension between O'Neill and Carter, and two different AlternateReality versions of Carter are either engaged or married to O'Neill. The "won't they" wins out in the prime reality largely because for most of the show's run, O'Neill is Carter's direct superior and is thus barred from pursuing her by the Air Force's anti-fraternization rules.
* WinToExit: In "Avatar," Teal'c needs to defeat the simulated Goa'uld invasion of the SGC in order to [[HolodeckMalfunction leave the chair]], as the programmed exit feature [[FailsafeFailure is not functioning]].
* WireDilemma: All the wires are yellow, so [[NoTimeToThink Jack has to guess which to cut]].
-->'''Col. O'Neill:''' "I'd like to take this opportunity to say that [[LampshadeHanging this is a very poorly designed bomb]], and I think we should say something to somebody about it when we get back."
* WithGreatPowerComesGreatInsanity:
** The Atoniek armbands, which grant the human members of SG-1 super strength, speed and senses, also impair their judgement and decision-making skills. They never quite reach the full level of "insanity", but they begin to disobey orders ([[MilitaryMaverick well, more than usual]]) and recklessly use their powers, starting a BarBrawl and inadvertently hospitalizing SGC personnel.
** In "Absolute Power", Shifu, the Harcesis Child, gave Daniel a vision of what would happen if he gave Daniel the colletive knowledge of the Goa'uld. Daniel would become a despot who would murder millions of innocents and regularly fantasize about being a Goa'uld.
* WithinParameters: Justified. Sam notices that the power level of a force shield surrounding the town they are in (protecting it from the poisonous wasteland outside) is dropping. The other scientist present insists it is nothing. He is being brainwashed by the computer.
* WithLyrics: The theme song was given lyrics in one DVD commentary, sung by the producers.
* {{Workaholic}}: Carter has little to no life outside of the SGC, and spends her free time in her lab on the base running various experiments. When she is finally ''ordered'' to spend some time away from work in "Ascension," she comments that she really does not have anything else to do.
* WontTakeYesForAnAnswer: When the SGC was first founded and its members began to wonder what kind of institution it would become, Daniel pushed heavily for the anthropological study of the civilizations they encounter to be given just as much a priority as military development. He was so ready to do battle with the pig-headed, stubborn military minds of the base that Hammond could not get out the words to tell him that he agreed and would be following up with studies of the people they encountered.
* WordOfGod: The cast has at times spoken about what ''they'' think was going on between the scenes and time-skips in the series finale, "Unending". In particular, Amanda Tapping and Christopher Judge said they played their interactions to imply Carter and Teal'c had developed a relationship, and either Claudia Black or Michael Shanks said the reason Vala's crying in one scene is because she miscarried.
* TheWorfBarrage: In the episode "Beachhead", an Ori force-field is powered by the weapons fired at it.
* TheWorldIsAlwaysDoomed:
-->'''Mitchell:''' I think that was dealt with when you guys saved the world for the sixth or seventh time.\\
'''O'Neill:''' Ah, who's counting?\\
'''Mitchell:''' Teal'c, apparently. He mentions it quite a lot.
** First mentioned in ''The Other Guys''
-->'''Felger:''' Don't worry, Colonel O'Neill, you can get back to saving the world for the sixth time.\\
'''Teal'c:''' Seventh.\\
'''O'Neill:''' You're counting?\\
'''Teal'c:''' ''(shrugs)''
* WorldOfBadass
* WorldHealingWave: The Dakara superweapon.
* WorthyOpponent: Arkad ''wants'' to be Teal'c's famed foe, and explains that he admired Teal'c's bravery and skill even when Teal'c killed his parents, but both Teal'c and Bra'tac have nothing but contempt for him.
* WrongGenreSavvy: When the team is faced with a very real dragon, Col. Mitchell suddenly decides he is some kind of dracologist and plans to kill it by setting off a brick of C-4 underneath it, since "that's where dragons are weakest." The dragon proves him to be very wrong.
* XTremeKoolLetterz: Martin explains that the title "Wormhole X-Treme!" was a marketing decision, since shows with the letter "x" in their title do better than other shows.
* YearInsideHourOutside
** In the series finale, Sam does this to keep the ''Odyssey'' from getting blown to smithereens while she uses the extra time to try and figure a way out of danger. The good news is that she succeeds. The bad news is that [[spoiler:it takes her fifty years]].
** This also happens at the start of [[spoiler:"Unnatural Selection"]]; at the end it is [[SealedEvilInACan Year Outside Hour Inside.]]
* YeOldeButcheredeEnglishe: Averted. When SG-1 finds a tablet written in Middle English it is indecipherable to O'Neill and can only be identified ''as'' English by Daniel, the archaeologist.
* YouAreInCommandNow:
** "Spirits" opens with O'Neill wounded by an arrow through the shoulder, forcing Carter to take command of SG-1 when they are sent through the gate to discover its source. O'Neill observes that it is her first command, commenting "cool."
** In "Lost City," General Hammond authorizes Carter to take command of SG-1 if she determines that the Ancient knowledge downloaded in O'Neill's mind is beginning to compromise his judgement. When she tells O'Neill of her orders, he says he understands and that she should take command ''now'' instead of waiting for him to lose control.
* YouAreNotReady: The standard explanation for why advanced alien races will not share their technology with us; the Asgard specifically explain that we are "too young." However, [[DeconstructedTrope unlike most examples of the trope]], the Asgard ''help us get ready''. They gradually introduced us to their technology, first giving us devices and later showing us how to manufacture them ourselves, so that we could appreciate their power and learn to handle them appropriately.
* YouAreTheTranslatedForeignWord:
** Kasuf says in "Forever in a Day" that Sha're/Amonet's son is ''harcesis'', "the one who holds the secrets."
** In "A Hundred Days," Daniel explains that the 'fire rain' is called a 'falling star' on Earth, and Tealc' then gives the Goa'uld name of the phenomena. After a moment, Daniel translates that to 'falling star.'
* YouCantGoHomeAgain: Jonas Quinn spent season six living on Earth and unable to return to his home, the nation Kelowna on the planet Langara, because he stole a quantity of naquadriah to give to the SGC.
* YouDidntAsk: In "Brief Candle" Daniel encounters Linear-A script, which has never been fully deciphered on Earth, but Teal'c recognizes it as an old dialect of Goa'uld. When he is able to read part of the script Daniel asks hy he did not mention it before, and Teal'c responds that Daniel "did not inquire."
* YouHadUsWorriedThere: O'Neill jumping an about-to-explode Stargate through the Earth, with a scare about whether or not he was able to eject.
* YouHaveGotToBeKiddingMe: Practically O'Neill's catch phrase.
* YouHaveFailedMe: Standard Goa'uld operating procedure.
* YouHave48Hours: "48 Hours".
* YouLookFamiliar:
** Mitchell Kosterman first appears in "Seth" as ATF Special Agent James Hamner, then again in "Heroes" as Colonel Tom Rundell.
** Dion Johnstone played a total of ''seven'' roles over the course of the show, often under heavy makeup. He played (In order): Captain Nelson in "Rules of Engagement," Na'onak in "Jolinar's Memory" and "The Devil You Know" (Before his mask was removed [[TheOtherDarrin and a new actor took over]]), an unnamed alien in "Foothold" (Identified as "Alien #2"), Chaka in "The First Ones" and "Beast of Burden," Lieutenant Tyler in "The Fifth Man," Wodan in "Metamorphosis" and Captain Warrick Finn in "Forsaken."
** David Palfy portrayed the Goa'uld Sokar in season three and returned as the robe-shrouded incorporeal form of Anubis from the end of season five up to "Lost City."
** Patrick Currie played three separate roles, but never actually looked the same in any of them: Two of his three roles were in heavy makeup as aliens. He was Chaka in "Enemy Mine," Eamon in "Space Race" and the Replicator Fifth in multiple episodes in seasons six and eight.
** Anne Marie [=DeLuise=] played Farrel in "The Other Side" and returned as Amy Vanderburg in "Bounty."
** David Lovgren first appeared as Va'lar in the episode "Threshold," reappearing as Darrell Grimes in "Bounty."
** Mike Dopud plays Russian Air Force Col. Ruslan Chernoshev in "Full Alert" and BountyHunter Odai Ventrell in "Bounty". He then reappears as Lucian Alliance member Varro in ''Series/StargateUniverse''.
* YouMeddlingKids: Daniel says the line at the end of "Bounty".
* YoungerThanTheyLook: The people of "Brief Candle" are all being artificially aged by Goa'uld technology at a rate of approximately one year per day. When he discovers this, O'Neill is rather disturbed to learn that the woman he slept with was not thirty years old, but thirty ''days'' old.
* YourCostumeNeedsWork: When O'Neill is on the set of "[[ShowWithinAShow Wormhole X-Treme!]]" he goes to the security office to get information on recent visitors to the studio. He is first told how to find the auditions, and then needs to add "really" after he explains that he is from the actual Air Force.
* YouRemindMeOfX: Teal'c once said that Mitchell reminded him heavily of O'Neill, which Mitchell took as a compliment. [[StealthInsult Teal'c said that that was up to him]].
* YourMom: In the fifth season episode "Failsafe", O'Neill and Jackson recount how a particular negotiation with the Asgard went south.
-->'''O'Neill:''' ... And after that, I kind of lost my temper.\\
'''Hammond:''' What exactly does ''that'' mean?\\
'''Jackson:''' Let's just say Jack made a reference to Freyr's mother.
* ZombieApocalypse: Mitchell's pitch for a story idea in "200" is that the Telchak device ([[ContinuityNod Previously seen in "Evolution"]]) is causing zombies to arise in the SGC. He is forced to [[GunsAkimbo battle them with two SMG's]].

None

Added DiffLines:

* SamusIsAGirl:
** The pilot had a (extremely brief) moment of confusion with regards to Carter. When General Hammond mentioned that their foremost expert on the stargate, Sam Carter, would be arriving soon, O'Neill asked where he was transferring from, only for Carter to walk in at that point and say that ''she'' is transferring from the Pentagon.
** Val Mal Doran was introduced in "Prometheus Unbound" in the armor of a Kull Warrior with an artificially-deepened voice. She had already taken the ''Prometheus'' and flirted with Daniel Jackson before the helmet was removed to reveal that she was a woman.
* SawStarWars27Times: Teal'c and O'Neill drop by Carter's place with pizza and StarWars, which O'Neill assumes must be be an okay movie because T's watched it nine times. Carter, however, thinks ''O'Neill'' is the weird one.
-->'''Carter:''' You've ''never'' watched ''Star Wars''?\\
'''O'Neill:''' Oh, come on Carter. [[HypocriticalHumor You know me and sci-fi]].
* ScaryDogmaticAliens: The Goa'uld and the Ori. After being indoctrinated by the Goa'uld over the millennia, the Jaffa look like this, especially the Free Jaffa Nation. Teal'c frequently shows irritation that they're stuck in the "old ways" even after they gained their freedom in Season 8.
* SciFiNameBuzzwords: When Vala [[OffToSeeTheWIzard pitches a story idea based on]] ''Film/TheWizardOfOz'', she tries to disguise it by renaming the primary events characters with stargate-themed titles. The house caught in a tornado becomes a cargo ship that crashes on a planet, the Wicked Witch of the East is the local ruling Goa'uld, Glinda the Good Witch is "a lovely, fair-haired Tok'ra" and Oz is a wise Ascended being. Martin Lloyd sees right through the whole thing.
* SciFiWritersHaveNoSenseOfScale: Averted. Traveling between different stellar systems, even at faster than light speeds, takes months or years (The fastest Goa'uld ship encountered can travel at 32,000 times the speed of light, which would take three years to cross the diameter of the Milky Way Galaxy), which is why the stargate network is still vital to the Goa'uld economy and military complex. The concept of conquering a planet requires millions of soldiers and defending a planet, even with technologically advanced weaponry, requires numerous weapons placed all around the planet, not just at vital areas. Multiple characters point out the flawed thinking of other people when they fall into the traditional pitfalls of discounting the sheer size of the universe.
* ScrewTheRulesIHaveConnections: After they have saved the world numerous times SG-1 is able to place direct calls to the President of the United States when they need a favor.
* ScrewTheRulesImDoingWhatsRight: This trope is used quite a bit.
** In the pilot episode, [[SpellMyNameWithAnS O'Neil(l)]] admits, in his roundabout way, that his report on the [[{{Stargate}} first trip]] was not ''completely'' accurate because a) genocide against the Abydonian slaves would not be right and b) technically, they ''did'' nuke Ra, who was the actual threat.
** In the first season episode "Enigma", Daniel Jackson goes against orders to help the Tollan get to their stargateless new world.
** In the first season finale "Within the Serpent's Grasp", the whole of SG-1 disobeys orders to launch a first strike against Apophis and his assault upon the planet after the [[ObstructiveBureaucrat Obstructive]] and CorruptBureaucrat [[WhatAnIdiot Senator Robert Kinsey]] shuts down Stargate Command.
** In the Ori arc, three ascended ancients are shown to do this to help humanity.
* SealedEvilInADuel: [[spoiler:Oma vs. Anubis.]]
* SeasonFinale
* SeinfeldianConversation: When Mitchell, Daniel and SG-22 have managed to capture a Prior, Mitchell spends a lengthy period trying to get the Prior to discuss the recipies of the Ori home galaxy. He, in turn, explains how to make a delicious omlette, and is disappointed when the Prior will not even give a pie crust.
* SelfDeprecation: Sam's [[DorkAge "Reproductive Organ" speech]] from the pilot returns only to be mocked in later seasons.
* SelfInsertFic: "Wormhole X-Treme!" reveals that when Martin originally wrote his treatment for the ShowWithinAShow, it had a fifth character based on himself, which he describes as a handsome alien marooned on Earth when his crew betrayed him. The executives took that part out.
* SelfParody: The self-referential episodes "Wormhole X-Treme!" and "200" revolve around the making of a ShowWithinAShow based on the exploits of SG-1, with many jokes and insults aimed at sci-fi cliches and past stories of the SGC.
* SemperFi: SG-3 is a dedicated combat support group composed of US Marines. It was originally commanded by Colonel Makepeace, former TropeNamer of HeroOfAnotherStory, and then led by Colonel Reynolds in the later seasons. SG-5 and SG-18 are also drawn from the Marines.
* SendInTheClones: Ba'al's clones (to great comedic effect) and, to a much lesser extent, the Asgard.
* ShaggyFrogStory: Combined with BrickJoke when O'Neill tries to tell the story about the dog and the dancing monkeys.
-->'''Col. O'Neill:''' Haven't you guys heard the story about the dog and the dancing monkeys? It's about getting along and... dancing.
* ShameIfSomethingHappened:
** In "Prodigy," when a group of scientists disparage O'Neill's experience and right to be in command, Teal'c walks up and "strongly advises" that the scientists listen to O'Neill. Afterwards, O'Neill calls Teal'c "[[LampshadeHanging Rocco]]."
** Arkad, a Jaffa hoping to lead others to follow the Ori, attempts to bully Earth into not opposing his plans by informing them of a plan to attack the planet that he can help them thwart. SG-1 and General Landry are well aware of exactly what he is doing, and do not even let him finish his speech before ridiculing his actions and likening him to a criminal thug.
* ShirtlessScene: Frequently.
* ShipTease: O'Neill and Carter being the biggest case. You know you are being teased when every non-military alternate version of Carter is married to the O'Neill of her reality.
* ShootTheShaggyDog: "Ethon". SG-1 successfully mediates a truce between the two nations, [[spoiler: only for them to destroy each other immediately after they leave]].
* ShotToTheHeart: Happens in the episode "Avatar," in which Teal'c gets trapped in a virtual reality training program that shocks him every time he dies to increase the realism. The doctor monitoring him has to administer an adrenaline shot when his heart stops after dying for the umpteenth time.
* ShowWithinAShow: ''Wormhole X-Treme!'', used twice to great comedic effect, including the celebrated 200th episode. Its original run was cancelled after airing three episodes, but it sold so well on DVD that the studio decided to give it a movie adaptation. The production of the movie was then frought with issues and the studio decided to cancel production, but decided to relaunch the series again and it aired for ten years, with the movie greenlighted (again) after the two-hundredth episode of the series.
* ShoutOut: Ohhh, so many.
** There are a whole lot of ''[[TheSimpsons Simpsons]]'' references throughout the series, since it is O'Neill's favorite show. Commentary on the DVD's reveals that these were included because it is Richard Dean Anderson's favorite show in real life.
** Carter's "It took fifteen years and three supercomputers to [=MacGyver=] a way to open the gate" line, improvised by Tapping.
** When Senator Kinsey laughs off the Goa'uld threat as no match for the U.S. military, Daniel mockingly says "What do you suggest we do, [[IndependenceDay upload a virus to their mothership?]]"
** Used with glee in "1969", with plenty of ''StarWars'' references, up to and including O'Neill introducing himself as "Luke Skywalker". (And [[StarTrek James T. Kirk]].)
** Season Three episode "Shades of Grey". "Hello, ''Newman''."
** The American submarine briefly mentioned in the episode "Small Victories" as being ready to destroy the Russian sub is named USS ''[[TheHuntForRedOctober Dallas]]''.
** In "Tangent", Daniel claims to be "The Great and Powerful Oz," which is only one of numerous references to ''Film/TheWizardOfOz'' throughout 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 [[StarTrekTheOriginalSeries Scotty]].
** In the episode "2010" Carter is involved with a plan to turn Jupiter into a star, referencing ArthurCClarke's book ''[[http://en.wikipedia.org/wiki/2010:_Odyssey_Two 2010: Odysey Two]]''. In the sequel "2001" [[LampshadeHanging Clarke and his novel is explicitly mentioned]].
** In "Wormhole X-Treme!" one of the aliens infiltrated the studio using the alias "[[SixMillionDollarMan Steve Austin]]."
** "The Other Guys" contains many references to ''StarTrek'', 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 [[RedShirt all in red]] and is killed soon after Coombs [[LampshadeHanging mentions that they are as likely to die as if they were wearing red shirts]].
** O'Neill wants to call the ''Prometheus'' the ''[[StarTrek Enterprise]]''.
** A season seven episode was actually titled "Film/EnemyMine".
** In "Avenger 2.0," Felger prominently packs a role of duct tape in his pack when he plans to go off-world with Carter. DVD audio commentary confirmed that this was reference to ''TheRedGreenShow'', 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 "[[LittleShopOfHorrors Seymour]]."
** Daniel called himself "Hans Olo" in "Prometheus Unbound".
** In the season nine episode "Ex Deus Machina", one of the persons of interest is the CEO of the [[IronMan Stark Constortium]].
** In season nine's "The Scourge," Mitchell motivates a tired bureaucrat to keep marching by making up "treeferrets," a dangerous arboreal creature that can separate a mans head from his shoulders. In the [[HonorHarrington Honorverse]], tree''cats'' are dangerous arboreal creatures that can separate a mans head from his shoulders, and are described as actually looking like ferrets, not cats. Later, when Mitchell and Teal'c [[CasualDangerDialogue 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 [[BugWar the horde of alien insects]], Mitchell explains that they are instead going to watch ''Film/StarshipTroopers''.
** 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 [[StarWars "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 KingArthur.
** 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 ''Film/BladeRunner'', which is administered to see if the subject is a replicant.
--> "'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 ''Series/{{Firefly}}'' and ''Film/{{Serenity}}''. "200" was a hurricane of [[ShoutOut Shout Outs]], with entire segments dedicated to ''StarTrek'', ''TheWizardOfOz'' and ''{{Series/Farscape}}'', as well as a short ''GilligansIsland'' reference.
* SideEffectsInclude:
-->'''Daniel:''' That warm, fuzzy feeling you're experiencing may be the effects of a device that is inhibiting your ability to concentrate and focus your powers.\\
'''Mitchell:''' Symptoms may include dizziness, irritability...\\
'''Daniel:''' Nausea.\\
'''Mitchell:''' Mild nausea, and a condition known as hot dog fingers.
* SigilSpam: You won't find the Ori symbol just on the Book of Origins' cover. In their galaxy, it is ''everywhere'' -- on the Prior's clothes, the crusaders' weapons, the fire pits they execute nonbelievers in, the power sources in their ships... even ''the ships themselves'' follow the pattern.
* SincerityMode: When discussing the Goa'uld Nerus, who has contacted the SGC in the hopes of working together against the Ori, General Landry says that he had nice things to say about SG-1. The scene then cuts to Daniel Jackson reading Nerus' communication and he remarks with surprise that Nerus really did have some very nice things to say about SG-1.
* SinisterMinister: The Canon on the medieval planet in "Demons" made use of ''creative'' interpretations of Literature/TheBible, the fear engendered by the Goa'uld System Lord Sokar's raids for hosts, and a [[AppliedPhlebotinum lightning-summoning ring]] in order to maintain control over his village. When SG-1 arrived, he accused Teal'c of consorting with demons.
* SingleBiomePlanet: {{Deconstructed}}, as the characters often decree the nature an entire planet based only on a brief exploration of the area surrounding the gate. One member concluded that she was on an "ice planet" when she found herself in Antarctica by mistake, and many characters point out that a day of exploration does not come close to discovering what might be just out of visual range.
* SkeletonGovernment: The Goa'uld.
* SlidingScaleOfIdealismVsCynicism: Contrasts Daniel Jackson, who cares about making friends and allies, to the NID, who care about getting technology to defend Earth at any cost, and Jack O'Neill, who is somewhere in the middle, mostly on the side of pragmatism. An example of the show running on different points of the scale is "Scorched Earth", where Daniel finds a way to save both civilizations vying for control of the planet's ecosystem despite Jack's plan to blow one of them up with a naqadah bomb, and "Entity", where Daniel and Sam's idealism leads to the latter being possessed by a vengeful (our probes accidentally caused damage to them) computer entity, even then Daniel insists Sam trying to make contact with the creature was not the wrong move. The entity only releases its hold on her when Jack threatens to send more probes. Jack basically has to tell Daniel to shut up, and let him do it his way.
* SoftSpokenSadist: The Goa'uld Tanith, who politely [[spoiler:wiped out the Tollans]].
* SomethingOnlyTheyWouldSay: In "Crystal Skull," O'Neill starts to believe that he really is talking to Daniel when Nicholas Ballard responds to one of his flippant remarks with "Jack, don't be an ass."
* SoProudOfYou: In "Talion," Bra'tac explains that Teal'c is [[LikeASonToMe like a son to him]] and that he is very proud of what he has accomplished.
* SoundEffectBleep: In "Heroes," O'Neill goes on a tirade against Senator Kinsey, most of which is drowned out by the alarm announcing an incoming wormhole.
* SpaceFighter: Notable in that the [[ScaryDogmaticAliens villains]] have space fighters from the very start, but the good guys have to develop theirs slowly over several seasons. As with all Goa'uld technology, their Death Gliders are [[CoolButInefficient more impressive than practical]].
* SpaceIsAnOcean: Partially averted, with space travel being in the hands of the Air Force. Most of the trappings of this trope are there, but they specifically avoid naval terminology; they use missiles instead of torpedoes, nobody says "port" or "starboard," the ships are flown by a pilot instead of a helmsman, etc. At the same time, given the size and purpose of the larger craft, it is apparently acceptable to refer to BC-303s and BC-304s (which ''do'' kinda look like flying aircraft carriers) as ''Prometheus''-class and ''Daedalus''-class '''ships''', respectively.
* SpaceMines: "The Serpent's Venom" takes place in a space minefield where the mines all lock onto any sign of weapons, which is used by the Goa'uld as a neutral meeting place. SG-1 has to reprogram a mine to attack one of the Goa'uld ships at the meeting in order to instigate a conflict.
* SpecialGuest: The US Air Force really likes this show. Enough that Generals and [=USAF=] Chiefs of Staff Michael E. Ryan and John P. Jumper made guest appearances as themselves.
* SpitTake: In "Ripple Effect" Colonel Mitchell gets into a rather animated conversation (With himself) about "the spit take of all spit takes."
* SpockSpeak: Teal'c. "Indeed."
* StalkingIsLove: Averted. Orlin claims that he loves Carter, but she explicitly points out that he is stalking her, and what they have is not a "relationship." She does warm up to him eventually, and even grows to like him, but she never falls in love with him in return.
* StandardStarshipScuffle: Increasingly frequent once the Tau'ri got {{Cool Starship}}s of their own.
* StandardSciFiArmy: Typical for television, the military forces are limited to infantry. Considering the Stargate limits how much can go through, it's justified.
* StarKilling: Samantha did this, [[RememberWhenYouBlewUpASun and got a trope named for her.]]
* StargateCity: This show is [[TropeNamer how Vancouver, British Columbia got that nickname]].
* TheStarscream: Ba'al, the most free-thinking and adaptable of the System Lords, rises from obscurity to become not just the most powerful one, but ''the only one left''.
* StatingTheSimpleSolution: When O'Neill was serving as a [[BackedByThePentagon technical advisor]] for "Wormhole X-Treme!" he overheard the executives debating how to have the character get past a giant alien guard, since budget constraints meant that they would need to re-write the previous plan of having him be weightless. When O'Neill asks [[WhyDontYaJustShootHim why he does not just shoot the guard]], they decide to go with that.
* SterilityPlague: In the BadFuture portrayed in "2010", the Aschen plan to surreptitiously conquer Earth involves one of these, distributed under cover of advanced medical tech. As shown in the later episode "2001", this is their ''modus operandi''.
* StockFootage: The gate dialing and opening -- sometimes subverted with powerful effect when things go wrong.
* StoryArc: At least one per season.
* StrangeMindsThinkAlike: General Landry has a habit of quoting famous historical generals, and he is in turn occasionally quoted by Colonel Mitchell. In "Counterstrike," Mitchell repeated a quote Landry had given, explaining it came from SunTzu, but he then amended that Landry might have actually been repeating DrPhil that time. In the next scene, when Landy provides a different quote to Bra'tac, who praises the wisdom of the warrior who provided it, Landry said that that time he ''was'' quoting Dr. Phil.
* StupidEvil: The Goa'uld; in "In the Line of Duty" Teal'c explains that he has seen certain victory turn to defeat simply because the Goa'uld cannot reign in their [[EvilGloating gloating]] or [[ForTheEvulz pointless sadism]].
* StupidSacrifice: Averted by the ever GenreSavvy O'Neill. After successfully destroying the shield system on an invading Goa'uld mothership, they ponder their next move. The following dialogue occurs:
-->'''O'Neill:''' Now what?\\
'''Bra'tac:''' Now, we die.\\
'''O'Neill:''' Well, ''that's'' a bad plan. Where's the glider bay?
* StyrofoamRocks:
** Played straight in "The Gamekeeper", which seemingly reveals that Daniel's parents died by being crushed inside an ancient cardboard temple.
** Parodied in "Wormhole X-Treme!" and [[DiscussedTrope discussed]] in the {{Troperiffic}} "200", in which an actor on the ShowWithinAShow complained about the career choices that led to him being pelted with StyrofoamRocks.
* SufficientlyAdvancedAlien:
** Despite the standard Goa'uld procedure of posing as a deity in order to rule a conquered people, [[AvertedTrope the technology of the Goa'uld does not qualify as Sufficiently Advanced]] as visible technology is directly connected to all accomplished feats.
** The Nox, introduced in the self-titled episode "The Nox", possessed the ability to raise the dead, teleport from point to point and become intangible/invisible at will. They accomplished these feats with woodland rituals, symbolic gestures and a philosphy which emphasized nature and pacifism. The end of their introductory episode reveals that they do ''have'' a technological city, but their skills and abilities do not visibly derive from it.
** The [[NoNameGiven unnamed aliens]] masquerading as the divine spirits of a group of Salish-descended people had the ability to change their shape and image, communicate telepathically and make people appear/disappear. This was accomplished with only a wave of their arms and was effective across interstellar distances.
* SuspiciouslySimilarSong: The dance scene at Mitchell's reunion in "Bounty" has several. When he dances with his old flame it is a pretty blatant Suspiciously Similar Song version of "Can't Fight This Feeling" by REO Speedwagon.
* SuspiciouslySimilarSubstitute:
** The trope was originally named "Jonas Quinn," after Daniel Jackson's replacement in season six when actor Michael Shanks left the show.
** Lieutenant Colonel Cameron Mitchell was added to the cast in season nine as a replacement for Jack O'Neill with the same humorous personality. [[YouRemindMeOfX Teal'c even commented that he reminded him of O'Neill]].
* SuspiciouslySpecificDenial: When the pilot was ReCut into a DTV movie, Carter's infamous "reproductive organs" line was removed in order to give the character more natural dialogue. Unfortunately, O'Neill's response is kept intact, so in the new film, instead of refuting an accusation that he is sexist, he instead brings up her gender apropos of absolutely nothing.
* SwordFight: Mitchell fights two of Merlin's holographic knights in season nine: The first is more of a [[OnlyTheWOrthyMayPass test]] than an actual enemy, and he manages to defeat it [[HeroicResolve after gaining a new determination]], but the second is a security device that is about to kill him when Daniel [[BigDamnHeroes comes to his rescue]].
* SympatheticCriminal: In "Bad Guys", SG-1 ends up playing this role, mostly by accident.
* SympatheticMurderBackstory: In "Collateral Damage", Cam recalls a mission in the Middle East during which he bombed what he believed to be enemy targets only to learn that they were a convoy of refugees.
