"You know, you blow up one sun and suddenly everyone expects you to walk on water."
— Samantha Carter
Stargate SG-1 is a popular Science Fiction series (1997-2007) following the Stargate movie (in a Broad Strokes fashion). It focuses on the adventures of the US Air Force's primary exploration and First Contact team, designated "SG-1," as they travel through a wormhole to alien planets and moons. The series dealt heavily with the Egyptian-mythology base of the original film, but as the series progressed it expanded to cover other mythologies and different alien threats and allies. This series is responsible for the elaborate expansion of the original Stargate Verse.As introduced in the movie, the stargates are a Portal Network that allow instant travel between planets that possess a stargate on them. As they travel to other worlds they find that almost All Myths Are True, at least in the form of Ancient Astronauts. Their primary foe throughout the series is the Goa'uld, a race of Puppeteer Parasites who are better known on Earth as the beings worshipped as the Egyptian Gods.Lasting for 10 seasons, it was one of the longest running Sci-Fi shows in US history and is only surpassed world-wide by Doctor Who. Despite the constant threat of cancellation from the 6th season on, and the fear of each Season Finale supposedly being the last, it came as a surprise when the show was not renewed for an 11th season almost immediately after it broke the prevous American-length record held by The X-Files. Two DVD movies have so far been made, Stargate: The Ark Of Truth and Stargate: Continuum; the third and final SG-1 movie, Stargate: Revolution, is currently in Development Hell.As the protagonists are primarily modern day Americans, Stargate's earthling characters rarely suffer from Genre Blindness. The main characters are very aware of the trappings of science fiction, and are not afraid to show it.Spinoffs: Stargate Atlantis, Stargate Universe, the animated non-canonStargate Infinity. For more info see Stargate Verse.A very sparsely-populated Recap page can be found here.It is available for viewing on Netflix Instant.
Aborted Arc: The events of "Camelot" reveal that the time of King Arthur's prophesied return is approaching and that Valencia is destined to help him after she pulls the sword from the stone. SG-1 does spend several episodes following Arthur's trail to several planets, and eventually discovers Merlin's anti-Ori weapon, but the prophecy of Arthur's return is never followed up or explored.
Absent-Minded Professor: When Sam meets her boyfriend in a coffee shop she mentions that there is no zoo in Colorado Springs. The screenwriters have heard of the Cheyenne Mountain Zoo, but the DVD commentary reveals that they wanted it clear that Sam has spent so much of her time working that she does not even know the layout of the city she lives and works in.
Abusive Precursors: The Goa'uld served as the foundation for many, if not all, human societies and religions prior to approximately 3000 BCE, but are a homicidal, imperialist and sadistic group that booby trap their leftover technology and return to exterminate any society descended from theirs that could rival them.
Amanda Tapping played multiple Carters in several different episodes. "Point Of View" had Dr. Samantha Carter, "Gemini" featured extended interactions between Carter and RepliCarter, and "Ripple Effect" featured over a dozen Carters in a single scene.
"Tin Man", where the alien Harlan created robotic duplicates of SG-1. They reappear in "Double Jeopardy," where the two O'Neill's get into a fistfight.
Guest star Dom DeLuise (briefly) as the title character and his creator in "Urgo".
Starting in season nine, Ba'al began cloning himself, with Cliff Simon playing multiple Ba'als in several episodes.
Action Survivor: Doctors Felger and Coombs have no combat training or experience, but when SG-1 was captured by Jaffa they both transport aboard the leaving ha'tak for a rescue mission. Of course, SG-1 allowed themselves to be captured and were quite unhappy to see the two scientists, but they came in handy later on.
The show was fond of making MacGyver references — which of course, leads to Celebrity Paradox. Lampshaded by Amanda Tapping in a blooper shown in the 200th episode special "Inside the 200th Episode" (Watch it here):
Amanda: You spent seven years on MacGyver and you can't figure this one out? We've got belt buckles, and shoelaces and a piece of gum; build a nuclear reactor for crying out loud! You used to be MacGyver, MacGadget, MacGimmick, now you're Mr. MacUseless! Dear God, I'm stuck on a glacier with MacGyver!
John Billinsley guest-starred in the season six episode "The Other Guys" as Dr. Coombs, who was a profound Trekkie. John Billinsley was at the same time starring as Dr. Phlox on Star Trek: Enterprise.
When Vala is pitching story ideas to Martin Lloyd in "200," he immediately recognizes her pitches as retreads of classic stories, including The Wizard of Oz and Gilligan's Island. He recommends that, if she is going to rip off something, make sure it is something nobody has ever heard of. Her next suggestion is Farscape, the series she (Claudia Black) and Mitchell (Ben Browder) had previously starred in before joining SG-1, with Claudia reprising her role as Aeryn Sun (Browder did not appear as John Crichton, but instead as Stark, while Michael Shanks was Crichton). Martin admits that he had never heard of that one.
The Goa'uld Hand Device (also called a "Ribbon device") is able to send a ribbon of energy into the head of another which causes extreme debilitating pain. This can be fatal if used extensively, and was also seen once to be able to send telepathic messages from one person to another.
The Goa'uld have a cattle-prod like device (never named in the series) that, when jabbed into a person, causes extreme pain without physical damage. When a person is being tortured with this 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.
Alien Non-Interference Clause: Rule number one amongst the Ascended Ancients, which they believe in so strongly that they would rather die than break it, is to not interfere on the lower planes of existence, primarily with regards to helping "lowers" likewise ascend. Their belief is that if you deserve to ascend then you can do it by yourself, and all beings have the right to chose their own path without interference, even if that path ends in their own death.
Aliens Speaking English: Almost all Transplanted Humans speak English, even if they were transplanted before the development of English or from a territory where it is not commonly spoken even today. Most alien species have their own language, occasionally featured heavily, but most of them can also speak English at need when they need to communicate with any present humans. This fact is lampshaded in the 100th Episode, "Wormhole X-Treme!"; when told that there can not be red apples on an alien world, the prop guy responds "Why not? They all speak English."
"Forever in a Day". There are hints throughout the episode, but the implication is that the episode is actually happening, but with dream interludes. It is only at the conclusion that the entire plot is revealed to have been only a fantasy.
"The Changeling" switches frequently between Teal'c's life at the SGC and a delusion where he is a human living a normal life on Earth. At the end, it is revealed that both lives were fantasies, and he was delusional as he struggled to keep both himself and Bra'tac alive after they were ambushed off-world.
All There in the Manual: DVD commentaries explain a lot of the thinking that the writers, directors and actors put into the show to explain events that were not explored in the show itself. This includes information on the private lives of the characters, their history, and what happens off-screen between episodes.
Alternate Universe: Many are visited throughout the course of the show, which subscribes to the "Different outcomes for each decision" school of thought.
Alternative Number System: A throwaway line in "The Fifth Race" reveals that the Ancients used base 8.
Always Chaotic Evil: The Goa'uld. Repeated use of the sarcophagus causes paranoia, megalomania and delusions, and their genetic memory passes down experiences from Queen to spawn. Because of this, the Goa'uld are literally born evil.
Always On Duty: Everything interesting seems to happen when the base commander, and the rest of SG-1, is around. Lampshaded on one occasion where O'Neill gets in just as an Offworld Activation is going on. Teal'c, Daniel, and Sam are already in the control room. O'Neill points out that he just got in early, and asks what the others are doing there. Teal'c still lives on base at this point, Daniel says he came in as soon as he heard someone new was dialing in (though it's implied he never left the base), and Sam...well, she had been working so late that she hadn't left yet. This distresses O'Neill, who had apparently ordered her to get a life.
Amazon Brigade: The Hak'tyl (Liberation), a planet of refugee women Jaffa in the season 7 episode "Birthright". They reappear in "Sacrifices" and later as members of the Free Jaffa Nation.
A Nazi by Any Other Name: In "The Other Side", the Eurondans are white supremacist eugenicists who have gone so far as to poison the entire surface of their planet in attempted ethnic cleansing. SG-1 royally throws a wrench into the works.
Ancient Astronauts: The basic premise of the show. The gods of most of the world's mythology and religion were actually aliens who masqueraded as gods; in some instances the aliens inspired the legends, whereas in other instances they adopted the already-existing identity. The two primary mythologies used by the series were Egyptian (primarily used by the Goa'uld) and Norse (used by the Asgard), though Mayan, Aztec, Greek, Chinese, Minoan, Japanese, Celtic, Semitic, Hindu, Yoruba, Zen Buddhist and Christian mythologies were also involved.
And Then What?: Seasons eight, nine and ten frequently highlight the fact that the Jaffa gave very little, if any, thought to what they would do after they overthrew the Goa'uld. This resulted in a lot of political infighting and presented many opportunities for unscrupulous people to take power through underhanded means. After the destruction of Dakara by the Ori, essentially destroying what government the Jaffa have, Teal'c and Bra'tac emphasize that it is just as important to plan for what to do after their victory as it is for them to fight the Ori.
"Spirits" opens with an arrow shot through the stargate that goes through a pane of bulletproof glass and still manages to wound O'Neill sufficiently to force Carter to take command of SG-1. Of course, it was a trinium arrow.
Area 51: Functions as a research and development site where technology is transferred after it has been brought back to the SGC. Stargate Command itself is once referred to as 'Area 52,' which is its code name for government budgetary reasons.
The metal armor worn by the Jaffa was extremely effective against Tau'ri weaponry in the early seasons (particularly in the first two fight scenes of the pilot), but was never seen to have any effect against staff weapons or zat'nik'tels. As the series progressed its effectiveness against projectile weaponry gradually lessened; by season eight it can even be penetrated by an arrow.
The armor worn by the Kull Warriors averted the trope. Though the Tau'ri and Tok'ra eventually developed an anti-Kull weapon, their armor remained impervious against both projectile and energy weaponry in every appearance.
Art Shift: In "Heroes", Emmett Bregman's footage has a different appearance from the rest of the show — more like a live TV program than Stargate's usual more cinema-like feel.
Ascended Meme: Fans of the show had for years used the term 'kawoosh' to refer to the unstable vortex of an opening stargate; in "Crusade," the penultimate episode of season nine, Carter uses the term.
Ascend to a Higher Plane of Existence: Trope Codifier. The Ancients Asceneded en masse and a few of their number, primarily Oma Desala, help other individuals ascend as well. However, their official policy is one of non-interference and they believe that anybody who should ascend will be able to do it by themselves. Daniel Jackson spent season six as an ascended being, but was forcibly returned to the normal plane in season seven. Season nine introduced the Ori, a sister-race to the Ancients who likewise ascended en masse, but believe in dominating the lower races in order to enhance their own power.
As Himself: Generals Michael E. Ryan and John P. Jumper, successive Chiefs of Staff of the Air Force, appeared on SG-1 playing themselves.
The Goa'uld select a Jaffa as their First Prime based on their military skill and experience. If a Jaffa wishes to depose the current leader he may challenge him to ritual combat for the position.
The traditions fostered by the Goa'uld are unfortunately very hard to get rid of once the Jaffa gain their independence, and the Free Jaffa Nation initially awards positions on its leadership council based on the military assets controlled by different Jaffa factions. This essentially gives Gerak, the former First Prime of the minor Goa'uld Montu, control of the new nation since Montu had served Ba'al and Gerak laid claim to the majority of Ba'al's forces.
Atlantis: The majority of season seven was spent searching for the Ancient's last and greatest city in the hope that its technology could protect Earth from the Goa'uld. In the episode "Lost City" they discover that this city, named "Atlantis," was formerly located in Antarctica, but that it has since moved. The spinoff, Stargate Atlantis, followed the expedition that located and explored the city itself.
Specifically the US Air Force. Multiple real-life Air Force Chiefs of Staff have appeared on the show, playing themselves.
In-universe, O'Neill is assigned as "technical advisor" to "Wormhole X-Treme!" to cover his activities on the set.
Back for the Dead: Major Kawalsky was one of three survivors of the original Abydos mission. He is taken over by a Goa'uld at the end of the pilot, and killed in the next episode.
Daniel Jackson was written out of the series at the end of season five when Michael Shanks left the series; the character ascended after exposure to a lethal amount of radiation. When Michael Shanks returned for season seven, the character descended to our plane of existence.
Apophis died at the end of "Serpent's Song," but was resurrected by Sokar for further torture and returned in 'The Devil You Know."
Badass: Teal'c can knock a man out with an avocado at 100 yards. He is the only character in the series to wield two weapons that are not meant to be used as such, including two staff weapons and even two P90s, and on occasion even carries a Death Glider cannon.
Badass Abnormal: The human members of SG-1 gain extreme strength, speed and senses while wearing the Atoniek armbands. They have the ability to kick through solid concrete, move faster than the human eye and see in almost complete darkness. Unfortunately, their judgement is compromised at the same time.
Samantha Carter is a decorated astrophysicist with complementary armed and unarmed combat training.
Daniel becomes a skilled combatant between seasons 1 and 10; unable to even properly reload his weapon in the early seasons but taking an active part in combat rescue missions in the latter.
Badass Crew: SG-1. Several enemies wanted to destroy the Earth just to ensure that those four would be dead.
Bad Future: "2010," which initially looks like a good future. The Goa'uld have been defeated, the Jaffa liberated, and Earth is a member of the Aschen Confederacy, which has granted the planet advanced technology. However, it turns out that the Aschen are simply a much more patient alien menace, and have been reducing human fertility with the plan to conquer the planet once the population has dropped significantly.
Teal'c before season eight, much to Christopher Judge's dismay, who regularly shaved his head.
General Hammond remained bald throughout the shows run and was even described as such by Colonel O'Neill on several occasions. Bra'tac had a habit of pantomiming Hammond's baldness when referring to him.
Bar Brawl: SG-1 starts a brawl at "O'Malley's in town" while under the mind-affecting, strength-enhancing Atoniek armbands.
O'Neill: Well, this is a cliché.
Battle in the Rain: It is raining throughout "Camelot" (Although it is very hard to notice on-screen) and, though it (Might have) stopped by the time of Mitchell's fight with the Black Knight, the ground is thick mud that ends up completely coating Mitchell as he is tossed around during the fight.
In the episode "Point of View", SG-1 travels to an alternate reality in which Teal'c is still First Prime of Apophis and the Goa'uld have taken over the Earth. The alternate Teal'c has a beard, as does Apophis, but this Teal'c is killed before he is really given a chance to show where he falls on the morality scale and Apophis is no worse (or better) than the "real" Apophis.
Lampshaded by Colonel Mitchell in "Ripple Effect:"
Mitchell: Well, you don't have beards, so I'm guessing you're not from the Evil Twin universe.
In a somewhat roundabout way, early episode "The Broca Divide" has Daniel's infamous (and soon forgotten) allergies prove to be beneficial, in that the antihistamine medication he takes for it proves to be the cure for the neanderthalism-inducing disease plaguing the locals.
In one episode, the characters receive armbands that bestow superpowers on the wearers. They work by infecting the wearer with a virus that causes the changes. Unfortunately this means that the armbands only work for as long as it takes the body to develop an immunity to the virus.
Beware the Nice Ones: Samantha Carter, the one member of SG-1 who never displays any personal hatred against the Goa'uld and who is the most level-headed of the group, is the one whose skill and experience named a trope.
Ba'al, a relatively minor Goa'uld who played second fiddle to numerous other Goa'uld, eventually managed to outlive and surpass them all in prominence and threat level.
The Ori replaced the Goa'uld as the ever-present Big Bad in seasons nine, ten and the first SG-1 movie, The Ark of Truth. They were represented by their Dark Messiah, Adria.
BFG: As the team's Big Guy, Teal'c is fond of these, be they squad-support machine-guns, grenade launchers, anti-armor missile launchers, or even a friggin Death-Glider cannon he slings from his broad shoulders.
When Jonas Quinn was introduced he became fascinated with "traditional all-American food" and was shown eating in every episode he was in, often more than once in an episode. Carter noticed this and commented that America has another tradition, hardened arteries, and this facet of his character was dropped towards the middle of the season.
Nerus, the Goa'uld inventor, whose appetites are so large, and so well known, that food is used as a method of information extraction.
Nerus: General! This chicken is most PLUMP and DELICIOUS. You spoil me general! Landry: It's called turkey, another rare delicacy. Nerus: Well I MUST have more turkey!
The Asgard are all that prevent the Goa'uld from launching an all-out attack on Earth that the planet would have no hope of surviving.
The Ascended Ancients are all that have kept our galaxy hidden from the Ori for millennia, and who prevent the Ori from using their Ascended abilities directly.
Big "NO!": Courtesy of Apophis and Anubis, and other Goa'uld. Being an entire race of megalomaniacal Large Hams, it fits.
The Big Race: Season seven episode called, appropriately, "Space Race."
Bilingual Backfire: In "The Scourge," Daniel Jackson and Shen Xiaoyi briefly converse in Mandarin, during which they briefly insult Mitchell, only for Mitchell to respond (In Mandarin) "Screw you!"
In "The Scourge," Daniel Jackson and Shen Xiaoyi briefly converse in Mandarin after being introduced.
Shen: How's your Mandarin? Jackson: Not as good as your English. Shen: It shows. (about Mitchell) You're bringing him along? Jackson: We have to baby-sit him. Mitchell: (in English) Yeah, that's very funny. (in Mandarin) Screw you!
Black Girl Dies First: Mala of the Hak'tyl was the only one of her tribe not to survive the tretonin tests.
Black Knight: Two of Merlin's holographic Knights appear in season nine. The first is a type of test to judge a challengers worthiness, and the second is a security system designed to protect Merlin's library. The first is dressed in shining armor, but the second, designed to scare the villagers and kill trespassers, is solid black.
Blue and Orange Morality / Above Good and Evil: One way to view the (non-human-form) Replicators. All they care about is making more of themselves. They have no interest at all in humanity or the other species, we are just in their way.
Board to Death: Ba'al to all his clones. At least most of them.
Body Backup Drive: The Asgard exist entirely as a race of clones, and regularly transfer their consciousness from one cloned body to a new one. Thor, voiced by Michael Shanks, dies repeatedly over the course of the series, only to return in a new cloned body.
Bothering by the Book: When a documentary begins filming the SGC, over the protests of General Hammond, Hammond explains that he will follow the precise letter of his orders, using minor technicalities to keep what he can out of view of the cameras.
Bottle Episode: Season eight's "Prometheus Unbound" and "Gemini" were filmed concurrently, each with only about half the cast, in an attempt to save money. Carter and Teal'c did not appear in "Prometheus Unbound," and O'Neill only had a single scene at the episode's opening, with Daniel only appearing in the opening scene of "Gemini." Ironically, due to the unexpected volume of special effects in "Prometheus Unbound," the episode wound up costing more than the usual SG-1 episode.
In "The Ties That Bind," Mitchell and Teal'c pose as bounty hunters in order to trick Jup and Tannat, two aliens that had a grudge against Vala and Daniel.
A whole batch of them come after SG-1 in "Bounty" after the Lucian Alliance puts a price on SG-1's heads.
Break the Cutie: Done to multiple characters, but SG-1 BEGINS with it being done to Daniel Jackson. The result is an understated subtext, but it's pretty clear the vengeance he wants is to exterminate the Goa'uld as a species.
Brick Joke: In "The Fifth Race", Jack and Teal'c spar in an boxing ring. Teal'c decks Jack. In "Upgrades", with the benefit of an Atoniek armband, Jack decks Teal'c.
Bug War: Season nine's "The Scourge," at the end of which the team decides to watch Starship Troopers for movie night.
A realistic depiction. When O'Neill is shot in the back with a silenced pistol the vest manages to stop one of the bullets, but the other bullet hit his (non-armored) shoulder and penetrated, and the impact from the bullet that was stopped still broke a rib and knocked him unconcious.
In "Heroes," Dr. Bill Lee explains why standard bulletproof vests do not work against staff weapon blasts, and in some cases actually amplify the affects of the blast, so the SGC develops a ceramic insert for the standard USAF flak jacket to absorb the blast.
Bullet Sparks: Particularly when machine-gunning enemy Jaffa.
Bunny-Ears Lawyer: Pretty much every major military role in the series is this to some extent. Jack O'Neill turns it Up to Eleven, by making insubordination into an art form.
Busman's Holiday: When Colonel Mitchell joins General Landry for a vacation at General O'Neill's cabin, they discuss hunting and Mitchell points out that his day job involves him walking around a forest with a gun. When he later is required to go out hunting (For a dangerous monster) he points out that it is just his day job all over again.
Sgt. Siler, as the Mauve Shirt who is constantly subjected to non-fatal accidents and injuries. It makes sense when you remember that his actor is the stunt coordinator for the series.
A darker version of the Butt Monkey would be Major Kawalsky, who was killed in the second episode. He reappears in time travel or alternate universe episodes only to die in most of them as well.
"The Changeling" recasts the members of SG-1 as firefighters living a normal life on Earth. Teal'c is a human, Bra'tac (Referred to as "Bray") is his stepfather who needs a kidney transplant, O'Neill is the fire chief, Carter is a crew captain and Jonas is "Probie" ('Probationary firefighter'). Daniel Jackson appears as a psychiatrist, but there are hints (And it is all but confirmed in the following season) that he is the real Daniel.
In "200," Vala pitched to Martin Lloyd a thinly-disguised retelling ofThe Wizard of Oz, describing it as an adventure she had before joining the SGC. Carter is the "lovely, fair-haired Tok'ra" (Glinda), Landry is the wise Ascended being (Oz) and Mitchell, Daniel and Teal'c are the Scarecrow, Cowardly Lion and Tin Man, respectively.
The Goa'uld literally have naquadah, the rare mineral that is used to build the Stargates and much Ancient and Goa'uld technology, in their blood. As such they can sense/be sensed by other Goa'uld, Jaffa or people who likewise have naquadah in their bloodstream.
The Reetou, an insectoid alien species that are invisible to all known species, can be "sensed" by the Goa'uld and, by extension, the Jaffa (through the Goa'uld symbiotes they carry). This "sensing" was used to develop a technology to make them visible.
In season six an alien device made whoever touched it (and whoever touched them) able to see alien creatures "out of phase" with our reality. The creatures themselves did absolutely nothing, they had been on Earth all along and could not interact with physical matter, but suddenly seeing them caused widespread panic.
Teal'c: A Serpent guard, a Horus guard, and a Setesh guard meet on a neutral planet. It is a tense moment. The Serpent guard's eyes glow. The Horus guard's beak glistens. The Setesh guard's... nose drips. (laughs uproariously)
Canon Discontinuity: The original rule for the zat'nik'tel was that one shot hurts, two kills and three disintegrates the body. However, as the seasons progressed the third shot effect was gradually dropped, disappearing entirely in season three. In the self-referential "Wormhole X-Treme!" the on-site director refers to the three shot rule as the stupidest thing he has ever heard.
The Jaffa cannot live without a Goa'uld in their pouch until a drug that has the same effect is discovered in one of the later seasons.
In the opening story arc of season nine, Daniel and Vala put on bracelets that create a link between them so that to be any more than a few feet away from each other can cause them extreme physical discomfort and eventually death.
Card-Carrying Villain: Anubis; when "Jim" is speaking with Daniel Jackson in the Astral Diner he explicitly points out that the Goa'uld are evil and that Anubis is the worst one of the lot.
Cargo Cult: More or less the basic premise of the show.
Cartwright Curse: Carter was known as "Black Widow Carter" behind the scenes as her romantic interests continuously died or were subjected to horrific torture throughout the series; she even acknowledges this to her boyfriend. Pete Shannahan was introduced in season seven partly because the writers specifically wanted to give Carter a life outside the Gate Program that did not end up being destroyed at the end of the episode where it was introduced.
Cast from Hit Points: When Daniel briefly becomes a Prior of the Ori and gains their powers, they work this way. He collapses from exhaustion when he exerts himself too much.
Casual Danger Dialogue: In season nine's "The Scourge," when Teal'c explains that he has always had faith in their ultimate triumph over the Ori, Mitchell remarks that with that mentality he is probably unconcerned with their current danger and already thinking about what they are going to watch for movie night. Teal'c responds that he was considering Old School.
Celebrity Resemblance: Actors Michael Shanks and Ben Browder got a lot of attention after the latter was added to the cast, due to their reported visual similarity. When Vala Mal Doran met the two of them at once, she commented that Earth has a "somewhat limited gene pool."
Characterization Marches On: When he is introduced in "Summit", Ba'al is described as a ruthless, sore loser who once wiped out two star systems rather than lose them to Cronus. This is quite different from the Affably EvilMagnificent Bastard of the last couple seasons.
Chekhov's Armoury: Everyone they meet. Everything they find. Everything they bring back. Everything they do to their Stargate beyond simple dialing. Even the Engaging Chevronsinvoked is a plot point in some episodes (because it is so slow).
In the beginning of "Wormhole X-Treme!" Martin gets into an argument with the "Prop guy" over which fruit to use for an alien setting. The same prop master later guides Martin to where the actual alien device is being used on the set and is revealed to be an agent of the NID.
When Mitchell is held captive by the Sodan in "Babylon" he briefly sees, but does not speak or interact with, the Prior that has come to convert them to Origin. In "The Fourth Horsemen," that Prior is revealed to be the source of the plague that is ravaging the Earth, and might also be the key to its cure.
Chick Magnet: It seems that every other female character will try to get into Daniel's pants at some point. Lampshaded in an early episode when O'Neill says at this rate, Daniel is going to have a girl on every planet.
Childless Dystopia: The Aschen Confederation offered the people of the planet Volia (P3A-194) a cure for a terrible disease on their world. However, the vaccine also resulted in sterility; the once thriving world of millions was reduced to chaos and riots, and then to a peaceful but empty world, with a few thousand apathetic residents and automated machines tending farmland. An earlier episode portrayed a Bad Future in which the same race was in the process of doing this to Earth.
The Chosen Zero: The Asgard ask SG-1 for help defeating the Replicators, because despite all of their intelligence they have yet to figure a way to defeat them. Earthlings, even though they are far less technologically advanced, have an ability to "think outside the box" that has allowed them to defeat the Replicators several times. Daniel summarizes this with, "Let me get this straight, you need someone dumber than you?"
Clip Show: Done once a season. Except for season eight's "Citizen Joe" each clip show advanced the plot of the series, sometimes radically, by framing the clips as the Stargate Program being introduced and explained to people who had previously not known its details. This format was used to reveal the Stargate program to the United Nations Security Council in season six and a new incoming United States President in season seven. Like everything else on the show, parodied in "200".
The Asgard are a dying race because they have lost the ability to reproduce sexually and their cloning technology is sufficiently imperfect that entropy must inevitably win.
The teenage clone O'Neill was a victim of genetic degradation because Loki had been sloppy and irresponsible in the cloning procedure.
Actually the fact that Jack's clone is only a teenager AND suffering from genetic degradation is more due to the fact that the other Asgards put a failsafe in Jack's DNA/Genetic code so that if someone like Loki tried to clone him for whatever reason, it wouldn't work properly.
Close Enough Timeline: "Moebius" ends with the revelation that there are now fish in Jack O'Neill's pond, whereas it had previously been completely devoid of fish. Word Of God has fluctuated back and forth as to whether or not this really was a different timeline, or if Jack had just been exaggerating when he had previously said his pond had no fish at all.
Jack wears the same outfit throughout "Abyss," and as the episode progresses there are more numerous holes and burn scars in his clothing after each torture session.
In "The Other Guys," Felger and Coombs disguise themselves as Jaffa by taking the armor off a pair of executed Free Jaffa. Both their sets of armor have staff blast holes from when their former wearers were killed, which they awkwardly try to cover.
Cold Equation: In "Tangent," Teal'c and O'Neill are Almost Out Of Oxygen and expect rescue in twenty-four hours, twelve hours after they will have died from CO2 poisoning. They recognize that if there was only one person left they might survive to rescue, and Teal'c puts himself in a deep meditation to stretch out their air supply.
Not as fancy as in the movie, but they appear in "Children of the God" with Apophis and the Serpent guards.
The Horus Guards have the same helmets as seen in the movie, but effect limitations meant that the actual collapse was usally hidden behind a cut. It was preserved in two episodes: Season two's "Secrets" and season eight's "Moebius."
Colonel Badass: SG-1 has one Colonel and two Lieutenant Colonels in its roster throughout the series, and all are sufficiently badass. Even the Colonel who was only on the team for a single episode, and was revealed as a mole, named a trope.
Comes Great Responsibility: The complete phrase is quoted verbatim when it is written on the Atoniek armbands, which grant their wearer extreme strength, speed and senses.
Commuting On A Bus: O'Neill was promoted to General so his onscreen time could be significantly reduced, reflecting Richard Dean Anderson's desire to spend more time with his family.
Compensating for Something: Vala accuses the chairman of the senate appropriations committee of wanting to build more Daedalus-class ships because he is compensating for his own shortcomings.
The Computer Is a Cheating Bastard: The training simulation in "Avatar" quite blatantly cheats when Teal'c is plugged in; it changes the rules of the game during play.
Conflict Killer: Season eight's "Reckoning" saw the commencement of the full-scale war between the rebel Jaffa and the Goa'uld, initiated by a series of surprise attacks on key Goa'uld facilities, only for the Replicators to attack the Milky Way and force the Goa'uld, Jaffa, Tok'ra and Tau'ri to work together.
Con Lang: Goa'uld, the language of (obviously) the Goa'uld, Tok'ra, Jaffa and majority of the humans of the Milky Way. The language uses a subject-verb-object grammatical structure, but with a much simplified tense formation compared to English. The language has multiple writing systems, based on various ancient Earth writing systems (Including Egyptian hieroglyphs and Linear-A), but most written Goa'uld seen on the show is a simple letter substitution, as opposed to actually being written in the language. The word "goa'uld" itself translates to English either as "gods" or "children of the Gods;" its usage varies.
In "Message in a Bottle", Carter remarks that the artifact they found has been emanating an energy signature since Neanderthals were a dominant species on Earth. Jack replies "Ah, takes me back", referencing the episode "Broca Divide", where O'Neill was turned into a cave-man on an alien planet.
This conversation in season seven's "Fragile Balance":
Hammond: Are you saying that O'Neill has somehow become 30 years younger overnight? Daniel: Stranger things have happened. Teal'c: Name but one. Daniel: Well, there was the time he got really old, the time he turned into a caveman, the time we all swapped bodies...
The episode "Heroes," though not a Clip Show, features the characters reviewing and explaining their adventures through the stargate up to that point in time. They make reference to important events in the lives of each character throughout the series, including events which they have agreed never to talk about again.
In "Moebius," Part 2, McKay attempts to justify the callsign "Gateship One" to General Hammond. This is a reference to the pilot episode of Stargate Atlantis, where he makes the same attempted justification to Dr. Weir.
In "Ripple Effect," Colonel Mitchell (One of them) mentions multiple situations where personnel of the SGC believe they have returned to Earth, only to learn they are being manipulated by aliens. He goes over the events of "Out of Mind" in season two, and the episode "Home" from season one of Stargate Atlantis.
In "Arthur's Mantle," Colonel Mitchell briefly runs through the various "alternates" that SG-1 has been through:
Mitchell: "... that was alternate realities, this is alternate dimensions, all I need is a good time-travel adventure and I'll have scored the SG-1 trifecta!"
When Daniel finally manages to travel to Atlantis in "The Pegasus Project," Vala remarks that his previous failures to get to the city were only her fault twice. Her first two appearances, "Prometheus Unbound" and "Avalon," both had her interfering with Daniel's plan to travel to Atlantis aboard one of the Earth's relief ships.
Converging Stream Weapon: The weapon made out of the six Eyes that Anubis uses on Abydos, in "Full Circle".
Cool, but Inefficient: Seems to be the central Goa'uld design philosophy. Lampshaded several times.
O'Neill: This [staff weapon] is a weapon of terror; it's made to intimidate the enemy. This [P90] is a weapon of war; it's made to kill your enemy.
The Ha'tak, Goa'uld pyramid ships, remain present and powerful throughout the entire series.
Ori ships: they are big, beautiful, practically invincible and need only one shot to blow up Goa'uld ship.
The BC-303 Prometheus was kind of cool, being the first human starship and the workhorse for humanity for three seasons. Then they introduced the BC-304 Odyssey and Daedalus ships, which are just awesome.
Also, the F-302 fighters.
Cool Old Guy: Hammond, Landry, Bra'tac and Jacob Carter.
The Coroner Doth Protest Too Much: Gerak's predecessor as the leader of the Free Jaffa that formerly served Ba'al, who was an ally of Bra'tac and supported the foundation of a democratic government, mysteriously disappeared four months before the start of season nine. Though no evidence linking Gerak to the disappearance has been discovered, and foul play was never definitively established at all, Teal'c and General Landry consider it more than just good fortune for Gerak.
Cosmopolitan Council: The Goa'uld, whose hosts are male, female, Caucasian, Black, Asian and various combinations thereof. Does not make them any less evil though.
In "Ascension," when Carter is trying to figure out how to deal with Orlin, who has shown that he will remain invisible if her superiors come looking for him, she approaches O'Neill with a "hypothetical" question about what to do in this situation and how, hypothetically, he might order her to proceed.
In season eights "New Order," when Dr. Weir explains why the SGC has remained closed during international negotiations, Daniel Jackson reads through her political phrasing and deduces that the government is using the stargate as a bargaining tool with other countries, to which Weir replies "I would never say that." Later in the episode, when Carter is asking to be allowed to take their Ancient-modified Goa'uld cargo ship in the hopes of contacting the Asgard to save O'Neill, she points out that Earth might never figure out how the ship was modified. Dr. Weir asks if Carter is saying that she, the person most likely to figure it out, will deliberately refuse to help if her request is not granted, to which Carter responds "I would never say that."
The text on the back of the DVD cover of the Swedish release of "Children of the Gods" (DVD release of the pilot episode) claims that the villains of the movie are Ra, "the brutal Goa'uld", and General Hammond. This is very not correct.
Crazy Enough to Work: SG-1 has racked up a fair number of wins with good old-fashioned tenacity and copious amounts of firepower. However, their best work usually involves doing things that sound flatly ridiculous, even to themselves. Lampshaded in one instance where, after Carter outlines her plan, O'Neill asks everyone who thinks it is an insane plan to raise their hands. The whole room does... including Carter.
Hammond: Keep those hands up, people. Because the next question is: who's going to make this happen?
Cruel and Unusual Death: Apparently, the Goa'uld Marduk was so evil that his own priests did a Heel Face Turn and sealed him in a healing Sarcophagus... together with a nasty little critter that would continuously devour his body while said Sarcophagus would heal and resurrect him. As O'Neill succinctly put it, that is officially the worst way to go.
Cryptic Conversation: Oma Desala and the nameless monk of "Maternal Instinct" speak frequently in Zen koans when guiding others towards Ascension. Daniel sometimes follows along, but often remarks on the confusing nature of these conversations.
Culture Clash: Teal'c's alien background occasionally deviates from what is expected amongst American society. When he encounters Colonel Maybourne in "Touchstone," he explains that on Chulak Maybourne's past actions would allow Teal'c to dismember him, and in "Affinity" he explains that if a Jaffa couple in a relationship cannot agree on a 'pledge break,' then a weapon is required to resolve the dispute.
Curse Cut Short: In "Möbius", when SG-1 gets taken out by a Jaffa grenade.
Cycle of Revenge: The nations of Rand and Caledonia finally had their long-expected war in "Icon," and are (slowly) rebuilding in the sequel episode, "Ethon." Unfortunately, both governments seem to be heading right back to war; Jared Kane, a senator of the Rand Protectorate, enlists the help of the SGC to derail the coming conflict. When his government demands to know why he is helping the enemy, Kane explains that he has no love for Caledonia, but he just does not want to see countless more people die (On either side) re-righting wars that were started by their fathers and their father's fathers.
Chairman of the Joint Chiefs of Staff: "You're a resourceful man Mr. Woolsey. If you think there's proof out there, find it."
Dark Age Europe: In the first season, when the show was still getting its footing and trying to explain why other human-populated planets, particularly the Tollan, had more advanced technology than Earth, Daniel explained that the Dark Ages held back our own technological advancement for several centuries. This idea was dropped soon after, since it has little real-world backing and is rooted in a European-centrist philosophy, which disregards scientific advancement from outside 'the West.' Later episodes would explain the technological disparity with in-universe rationales; including contact with other advanced races, the development of a single key technology that accelerated their progress, or even just the random vagaries of chance.
Dr. Jay Felger is prone to them, as both of his episodes end with a fantasy segue. "The Other Guys" closes with both him and Coombs being awarded medals, before Carter begins to make out with Felger upon the dais. "Avenger 2.0" closes with him and his assistant making out before Carter comes in and engages his assistant in a Cat Fight over his affections.
In the episode "Grace" Carter has repeated hallucinations of her friends and family, several appear (And might be, or might not be) real.
The Dead Have Names: Inverted at the memorial service at the end of "Heroes." During the eulogy, Carter mentions the names of everybody who is alive thanks to the work of Janet Fraiser.
Deadpan Snarker: Jack O'Neill, with Daniel Jackson occasionally getting into the act; the latter mentions, after annoying a Russian officer, that he has been spending too much time with Jack. People meeting Jack for the first time will sometimes ask the question, "Is he always like this?"
Ba'al: You dare mock me? O'Neill: Ba'al, come on, you should know me by now. Of course I dare mock you.
Balinsky: Dr. Jackson's going to die when he sees this! Dixon: Again?
Thor, and by extension all the Asgard, are effectively immortal since they transfer their minds to a new cloned body in the event that their current body is destroyed or lost. Thor dies multiple times throughout the series, only to return later with a new body. Fittingly, he is voiced by Michael Shanks, Daniel Jackson's actor.
In the episode "Abyss", Jack is tortured to death several times by Ba'al, only to be resurrected in a sarcophagus so Ba'al can start over again.
Apophis is one character whose number of deaths rival Daniel Jackson, as he has been presumed dead (and actually dead) so many times that, when he was finally Killed Off for Real, Jack corrected himself from "100% sure" down to "99% sure". Despite being Killed Off for Real, he was brought back multiple times in alternate realities and dreams/hallucinations.
Delivery Guy: Daniel Jackson in "Brief Candle," where the team stumbles upon a woman giving birth in an empty temple, and again in "Secrets," when Sha're, Goa'uld-infested and heavily pregnant with Apophis' child, goes into labor.
Department of Redundancy Department: O'Neill gives Lieutenant Satterfield, a trainee hoping to join the SGC, "high marks for her high marks."
Descending Ceiling: Part of the test of wisdom in Merlin's chamber at Avalon.
In "Ethon," when Kane asks if Daniel Jackson ever gives up, he says that he does not give up until he is dead, and sometimes not even then.
Teal'c manages to fight, defeat and execute Arkad after having been shot twice before the fight even began and being beaten and gutted during the struggle.
Development Gag: The ending of "200," where the Wormhole X-Treme! movie production is cancelled in favor of renewing the TV series, reflects the actual status of SG-1 during production of seasons five, six and seven, where the intention was to end the series after each season and conclude the story with a movie. However, the show kept getting renewed instead, and the plan for the movie was eventually scrapped and turned into the season seven finale "Lost City."
O'Neill will only allow a Russian officer to join SG-1 over "[his] rotting corpse," to which he then amends "Did I say that out loud?"
When President Hayes is made aware of the stargate, and Vice-President Kinsey's association with the project, he begins to wonder about some of the campaign financing that Kinsey had brought to their election. When the Chairman of the Joint Chiefs of Staff reacts to his statement, he smirks and responds "did I say that out loud?"
Die Hard on an X: "Bad Guys" places SG-1 in the role of the villains, accidentally taking a museum hostage on an alien planet when they are mistaken for rebels. When a security guard manages to avoid being captured and later tries to foil their "evil plan" Mitchell refers to him as "John McClane," which Daniel does not understand, so Teal'c explains that he is referring to the movie.
Digging Yourself Deeper: When Vala is being reviewed for suitability to formally join the SGC, she is given a polygraph. Vala tries for some generic small talk and compliments the doctor administering the test, only for the polygraph to flash and indicate that she is lying. After each flash she tries to amend her statement, lowering the compliment each time, until she finally says that the doctor looks "not offensive."
Directed by Cast Member: Amanda Tapping, Michael Shanks, and Christopher Judge all wrote or directed episodes, and Ben Browder shared a story credit for one episode.
Colonel Samuels, an NID-affiliated officer, smugly presented his "Goa'uld buster" weapons as the key to defeating Apophis' attack on Earth in "The Serpent's Lair." When the attack failed to have any appreciable affect, and his subsequent suggestion to send a nuclear weapon to Chulak was overruled as being pointless, he requested to evacuate to the Alpha Site. General Hammond seemed to almost take glee in denying his request, explaining that the idea was to send the best and brightest and Samuels did not qualify.
Robert Kinsey attempts to flee Earth to the Alpha Site as soon as Anubis launches his attack, despite learning that President Hayes is staying at the White House, and visibly panics when Anubis tries to send a bomb through the gate to the SGC.
The first season episode "Hathor" was widely disliked by fans and, though the Hathor character did reappear, the specific details of the episode were never revisited. In follow-up episodes, whenever the events were discussed one of the characters would comment that they had agreed never to talk about that again.
In "Wormhole X-Treme!" the on-set director of the Show Within a Show referred to Martin's suggestion of 'three shots disintegrates' as the stupidest thing he had ever heard. The ability of zats to disintegrate a body with three shots had been dropped in season three.
In the pilot, Carter mistakes O'Neill's dislike of having her assigned to his team as a feeling that, as a woman, she will be a liability. O'Neill explained that his problems had nothing to do with her being a woman, he likes women, his problem is that she is a scientist. The conversation, including the infamous "reproductive organs" line, was edited down when the pilot was re-released as a Direct-To-DVD film in 2009.
Inverted in "The Other Side." The Eurondans are extremely uncomfortable around Teal'c, with the implication that it is because he is a Jaffa, but it turns out that they are just regular old "hate black people" racists, regardless of their planet of origin.
Inverted in one episode, when Daniel (who has at this point Ascended to a Higher Plane of Existence) shows up again, and O'Neill immediately asks him what's wrong. Daniel gets upset because O'Neill didn't even bother with such basic pleasantries as saying hello to him first.
O'Neill inverts it himself at another point, when Jacob comes through the Stargate:
O'Neill: Jacob! Jacob: Jack, we've got a problem. We need to talk. O'Neill: Hi! Hello. How are ya? Long time, no see. What's doing? What's up? Hey, buddy! Jacob: I'm sorry, Jack. It's good to see you again. Congratulations on your promotion. O'Neill: Thanks. Jacob: You deserve it. O'Neill: Yes. Well... What's up? Jacob: The Replicators. They've launched an all-out attack on the Goa'uld. If the Goa'uld can't find a way to stop them, the Replicators will easily overrun our galaxy, in a matter of weeks. O'Neill: Why didn't you say so? (Jacob gives O'Neill a look and walks off) O'Neill:(after a pause, hurrying after Jacob) I'm sorry. You said we have a problem, not a big galactic emergency.
Distracted by the Sexy: In "Upgrades," O'Neill goes on a tear about the Tok'ra and his dislike of them, only to trail off when Anise steps through the gate.
Ditto Aliens: All the Asgard are portrayed by the same puppet, and O'Neill often needs to be prodded to recognize one of them as Thor. Carter, however, seems have no trouble at all identifying different Asgard by sight.
Divided We Fall: The Jaffa rebellion was severely hampered throughout its existence by the inability of the separate factions to coordinate and work together. There was at least one outright betrayal in "Avenger 2.0", and "Sacrifices" highlighted the disparate goals of each individual faction.
In "Tangent," Major Davis introduces General Vedrine to SG-1 and each is greeted with their salutation (Colonel, Major and Doctor), each responding with "General."
The episode "Frozen" has Dr. Fraiser being introduced to the Antarctic team, leading to a chorus of "doctor"s (and a few "Majors" thrown in for Carter) before O'Neill interrupts and tells them that's enough.
Documentary Episode: The two-part episode "Heroes," which features Emmett Bregman filming a project on the SGC and its personnel at the direction of the outgoing US President. This includes interviews with the primary cast and several of the recurring supporting characters, discussions of past events, and debates on whether or not the program should be kept secret from the public. Scenes from the documentary are filmed with different lighting and staging to reflect the presence of an in-show camera.
Does Not Know His Own Strength: When SG-1 puts on the Atoniek armbands, which grants them super strength, speed and senses, Jack O'Neill seems to have a lot of trouble adjusting. When it first takes effect, he manages to knock Teal'c unconscious in a boxing ring. Later, he accidentally knocks out part of Hammond's concrete wall to demonstrate what they can do and, afterwards, accidentally hospitalizes Sergeant Siler when he knocks him down a flight of stairs.
Doing It for the Art: One of the "flashbacks" from "200" featured an incident where O'Neill was rendered invisible; one of the scenes featured him walking down a hallway and talking with Teal'c, but since he was invisible he could only be located by the coffeee cup that he was carrying at the time. The plan was to have one of Richard Dean Anderson's stand-ins or stunt-doubles actually perform the scene, since it would require wearing a full-body green suit in order to have the body edited out in post production, but RDA insisted on actually performing the scene himself. You still cannot see him, since he is invisible, but hopefully you can just tell that it is really O'Neill walking with Teal'c.
Don't Call Me Sir: Emmett Bregman, shooting a documentary of the SGC, repeatedly tells the colonel of Cheyenne Mountain public relations to call him Emmett, to which the colonel always responds "Yes, sir."
Dramatic Irony: Some of the friction between Captain Carter and her father stems from what he considers to be her abandonment of her dream of going into space and her wasting her potential working in Cheyenne mountain; he pulls strings to have her transferred to NASA, which she rejects. If only he knew that she was going into space on a daily basis, farther than any NASA shuttle will ever go.
In "The Light," Daniel and the members of SG-5 go through withdrawl after leaving a Goa'uld "opium den" (Note: Not actually about opium), and attempt to kill themselves. The episode opens with Lieutenant Bader running directly into the kawoosh of an opening stargate.
When Jack accepts that Daniel cannot, or will not, use his Ascended powers to break him out of Ba'al's prison, he demands that Daniel at least kill him to keep him from being tortured and killed over and over again, and becomes enraged when Daniel refuses to do.
In "Forever in a Day," an Abydonian funeral is witnessed. It draws heavily from Egyptian funerary rights, including the preservation of organs in canopic jars and weighing the deceased heart against a feather.
Jaffa funerals take place at night, with the body immolated on funeral pyre.
The Tok'ra have a funerary ritual involving the disintegration of their bodies in the vortex of an opening stargate in order to prevent the Goa'uld from learning any information from their corpses or resurrecting them in a sarcophagus for interrogation. The eulogy points out that even in death they do not give in to the Goa'uld.
Part two of "Heroes" closes with a memorial service for Janet Fraiser with Major Carter giving the eulogy.
Dull Surprise: The main cast criticized themselves for the ending to "Thor's Chariot," where they only seemed mildly intrigued by the sight of a ship the size of a city appearing and eliminating an entire Goa'uld army in seconds. In behind-the-scenes interviews, they explained that none of them appreciated just how impressive (or big) the ship would look in the finished episode, so they did not think to put more awe or fear into their expressions.
Dynamic Entry: In "Talion," Teal'c kidnaps Ba'kal by walking out of the shadows and knocking him out with a blow to the face.
Early Installment Weirdness: The later seasons definitively established that beings with naquadah in their bloodstream, including Jaffa, could "sense" other beings that likewise had naquadah in their blood, primarily Goa'uld (and Tok'ra) symbiotes. However, this was completely absent from the first season, and in "In The Line of Duty," the first episode to feature the ability, Teal'c never sensed the presence of Jolinar.
Endless Daytime: In "The Broca Divide", the heroes visit a planet that is tidally locked. While the inhabitants of the "light side" have a Bronze Age culture bearing similarities to the Minoan civilization, the dark side is infected with a plague that turns people into savages.
Season seven had an episode titled "Enemy Mine" that referred to the movie by actually featuring a mine; the SGC must negotiate with the native Unas population for mining rights to a deposit of naqahdah.
The SGC and the System Lord Yu coordinate their attacks against Anubis when it becomes clear that his advantage over the rest of the Goa'uld is too great, and the SGC then assists Ba'al with the same when Yu's senility makes his cooperation unpredictable.
The Tau'ri, Tok'ra and rebel Jaffa cooperate with the Goa'uld against the Replicators, who launched a full-scale invasion of the Milky Way in "Reckoning."
Entertainingly Wrong: In "Arthur's Mantle", Dr. Lee concludes that Sam and Cam were miniaturized, when actually they were sent into another dimension.
Epic Fail: As Dr. Felger explains, it probably took the Ancients thousands of years to build the stargate network, and he managed to take it down in a day.
Estrogen Brigade Bait: Teal'c spends much of his screen time in practically sprayed on sleeveless T-shirts. In later seasons, Daniel manages a few Shirtless Scenes that show just how much he has benefited from all his physical activity.
Sokar was deemed as being far worse than his fellow System Lords and was ejected from their ranks.
Anubis was banished by the System Lords millennia ago for crimes even they found unspeakable, and they put aside their constant in-fighting to join forces against him after he returned.
Everybody Hates Hades: Well, Sokar, who was just a normal god of underworld, but the Goa'uld who adopted the identity actually modelled himself on Satan.
Everyone Can See It: By the end of season eight, Carter and O'Neill's attraction has reached a point where multiple characters tell them to stop wasting time and get together already. Vice-President Kinsey explains that it is apparent to anybody who can "read between the lines."
Eviler than Thou: Anubis. See Card-Carrying Villain above. He was opposed, at one time or another, by pretty much every remaining major villain on the show, sometimes in conjunction with SG-1.
Sokar's prison moon Netu in "Jolinar's Memories" and "The Devil You Know" was explicitly modeled on Hell, as Sokar impersonates Satan.
It is discussed after the introduction of the Ori that fire has historically been associated with demons; Daniel hypothesizes that the Ancients might have deliberately fostered this belief in order to subconciously prejudice humanity against the fire-themed Ori.
The Goa'uld have deep, reverberating voices that they use to awe their followers. The Tok'ra subvert the trope; being biologically Goa'uld their voices are just as deep and reverberating, but they are among the good guys.
The Kull warrior suits artificially lower the voice of the wearer.
Evil Versus Evil: Anubis vs. System Lords; Replicators vs. System Lords; Ba'al vs. Adria.
Exposed Extraterrestrials: The Asgard are highly advanced grey space aliens that do not wear clothes. Given that they reproduce via cloning, perhaps they no longer have anything they would consider private parts. Lampshaded in "Ripple Effect;" Col. Mitchell is surprised on first meeting one, and remarks that he was kind of expecting pants.
Expy: The Goa'uld bear many similarities to a creature encountered by the Enterprise in Star Trek The Next Generation in season one: a worm-like creature that attaches to the spinal cord, cannot be removed, grants superhuman strength and assumes control of the host body.
Famed in Story: SG-1 is legendary throughout the galaxy, but Teal'c is particularly famous (Or infamous) as 'the shol'va' (traitor) who started the Jaffa rebellion and almost personally lead to the downfall of the Goa'uld.
Fantastic Racism: In abundance, as well as the old-fashioned kind in the episode "The Other Side", wherein the aliens of the week disliked Teal'c not because he was Jaffa, but because he was black.
Fatal Attractor: Daniel Jackson was continuously involved with women who turn evil, have been evil, or become a Goa'uld host. The only person with worse luck in love than Daniel is Carter.
Fatal Family Photo: Airman Wells spends the entire first part of "Heroes" showing the ultrasound of his unborn son to the rest of his team, up until he is shot in the back by a Jaffa. He survives.
Fate Worse than Death: Becoming a Goa'uld host. Imagine being trapped in your own body, being able to see and hear everything around you, but be powerless to do anything. Now imagine living through this for hundreds or even thousands of years. If you're lucky, you'll go insane long before then.
The Tok'ra allow Tanith to live and believe that he has tricked them in order to feed Apophis false information through him. They decide to stop the subterfuge once they feel that he has outlived his usefulness and the risks of keeping him around outweigh the gains.
In "The Other Guys" SG-1 allows themselves to be captured by the Goa'uld Khonsu since they know he is actually a Tok'ra and he has vital information to pass along. However, midway through the episode Her'ak, Khonsu's first prime, reveals that Anubis knew the truth the whole time, and they had simply allowed Khonsu to live until now. Her'ak kills Khonsu and SG-1 is now captive for real.
Emmett Bregman, shooting a documentary at the SGC, repeatedly tells the colonel he is working with not to call him sir. In their final scene, he finally does call him 'Emmett.'
At the end of "Lost City," when O'Neill is fading away due to the Ancient knowledge downloaded into his mind, Carter pleads for him to stay and calls him "Jack."
After Jack has been promoted to General, Hammond insists that he start calling him "George," but Jack says that he tries and it comes out 'General' anyway.
The "Previously on..." opening to "The Sentinel" featured footage from "Shades of Grey" in order to re-introduce the rogue NID operation that would be important in the episode, but the two NID characters who 'returned' did not actually appear in "Shades of Grey." They were edited into the older scenes in order to give the impression that they had been there all along.
In "200," when discussing possible endings to the Wormhole X-Treme! movie, "fishing" is mentioned, complete with clips from the season eight episode "Moebius" where the season did end with the team going fishing. There is, however, an added clip that includes Mitchell and Vala, who had not yet joined the cast, and O'Neill testily responds that they were not there.
Flashed Badge Hijack: Mitchell takes a man's motorcycle when he needs to pursue the people who have kidnapped Vala, and the car he and SG-1 are driving is blocked in its space...by a police car.
Flynning: When Mitchell sees two siblings play-fighting with wooden swords, he criticizes them for "moving around like Ed Grimley" and demonstrates a more effective technique in order to gain their favor. When they ask where he learned to fight, he explains that his knowledge comes from broomstick battles with his brother and the Sodan ritual of kel-shek-lo. Oddly, his prior mention of studying fencing in college was not brought up.
First Contact Math: The Asgard do not reveal their true selves to a people until they have demonstrated that they understand pi (The ratio of a circle's radius to its circumference), indicating that they have developed sufficient science to understand their existence as "aliens" and not "gods."
Fixed Forward Facing Weapon: The Ori mother ships have a massive slow firing weapon that frequently decimates any ship it hits. They also carry turrets similar to those on a Ha'tak, but much more powerful (though the main beam still outclasses those by leaps and bounds).
Freeze Frame Bonus: In "The Fifth Race", just after he comes back from the planet and is in the briefing room, O'Neill is sketching absent-mindedly the plans for a makeshift ZPM.
Friendly Enemy: The Goa'uld Nerus, who has contacted the SGC in the hopes of working together against the Ori, is almost giddy with anticipation over meeting SG-1, fawning over Teal'c and Daniel Jackson. When he realizes that Colonel Mitchell and Vala are not O'Neill or Carter he becomes despondent, even asking if they might be arriving later.
Forgotten Phlebotinum: Since a major part of SG-1's mission statement is to find useful technology this is averted a lot, with some technology appearing frequently over the years after its introduction, but a lot of other technology is forgotten once its episode is over.
For the Evulz: In "In the Line of Duty," Teal'c explains that he has seen the Goa'uld exterminate entire species for no purpose other than that it gave them pleasure.
Doctor Samantha Carter: Well if you're not gonna give us a second chance... I don't know any of you. Jack: Well, exactly — you don't know any of us. And we don't know you. For all we know, you could be her evil twin! But then we'd be dealing with clichés, and you know how I feel about those. (turns to Major Carter from his reality) Jack: No, actually you know how I feel about them.
Aris Boch: And you, O'Neill, you're considered, well you're a pain in the nik'tah. O'Neill: Neck? Teal'c: No.
Jack in Absolute Power.
Shifu: A spark lights a flame, but the candle will burn only as long as the wick.
Jack: If I may sir, I think what he means is, the wick is the centre of the candle, and obstensively a great leader, like yourself, is essential to the whole ball of wax. Basically what it means is is that its better to have a big... long... wick right?
Ghost City: In "Bane", "Ascension", "2001", and "Menace".
The Goa'uld take on the persona of gods of Earth's early mythologies. Some of the more deluded, such as Ra, Anubis, and Apophis, seem to buy into their own hype and actually believe themselves to be Gods, while others, like Ba'al, are aware that the Goa'uld are just parasitic snakes and only play the role of being divine to maintain their power.
The Asgard use holgrams to depict themselves as the gods of the Norse pantheon, but only to primitive peoples under their protection who would not understand the concept of "aliens." They include tests within their "religious" sites to let them know when the population is ready to hear the truth.
God Emperor / God Guise: Standard Goa'uld PR theme. Sufficiently advanced technology makes it easy for them to pass as classical pantheonic gods, and thanks to their ridiculous egos and the mind-screwery of the sarcophagi some of them even believe it themselves.
A God I Am Not: The ascended Ancients refuse to be worshipped or thought of as gods. The Ori on the other hand...
Gods Need Prayer Badly: The Ori manage to sap power from their worshipers, which is why they foster the religion of Origin.
God Test: When Gerak becomes a Prior of the Ori and is asked to destroy Jaffa who refuse to believe, Teal'c asks him what makes him believe they are gods, citing various impressive miracles they could have performed. He then points out that the Goa'uld performed the exact same miracles and posits that the measure of a god is not how much power they have, but how they apply it. If they were gods, they would not need Gerak to kill anyone on their behalf, or even ask such a thing of him.
Goal Oriented Evolution: Averted in the initial seasons, where scientists find the idea of duplicate evolution of genetically compatible species to be completely unbelievable, and Ascension is a philosophical concept, unconnected to evolution in any way. However, towards the end of the series, and especially after the Ori are introduced in season nine, humans are explicitly described as evolving on "a path to Ascension," which has been repeated with at least four different branches of humanity that evolved independent of one another (The Ancients, humans of the Milky Way, humans of the Pegasus Galaxy, and the humans of the Ori Galaxy). Eventually, the philosophical portions of Ascension are dropped completely, and people can only Ascend at the conclusion of their "natural" evolution, and it comes regardless of their moral or spiritual status.
Going Down With the Ship: Colonel Lionel Pendergast aboard the Prometheus, who stays aboard to make sure that his crew can evacuate down to the planet surface.
Good Bad Bug: An in-universe example, where when replicator bugs took over a Goa'uld ship, they caused a security breach that allowed our heroes to escape a room they had been locked in.
Grammar Nazi: Ironically, O'Neill does this often. Even while being tortured, he corrects the villain's grammar.
Jaffa: No matter what you've endured, you've never experienced the likes of what Anubis is capable of! O'Neill: You ended that sentence with a preposition... bastard!
Green Eggs: Played straight in season 4's "Beneath the Surface"; lampshaded the following season, in "Wormhole X-Treme!"
Green-Skinned Space Babe: Anise/Freya of the Tok'ra is a sexy female alien with sexual tension with both Daniel Jackson and Jack O'Neill (Freya, the host, likes Jack, but Anise, the symbiote, likes Daniel).
Groundhog Day Loop: The mostly-comedic "Window of Opportunity" episode, a fan favorite.
The Guards Must Be Crazy: For once the bad guys do not hold a monopoly on this trope, as incompetence is the general order of guards in the SG-1 universe.
When an Ashrak infiltrates the SGC in order to kill Captain Carter he is found standing over her body by several security guards. He states that she is dead, shouts "Let's go" and starts running. He does not say where they are going or why they are going anywhere, but because he is dressed as an Airman the guards follow him as he runs...somewhere.
When the Tok'ra are planning to surgically remove the Goa'uld Tanith from his host, he claims that he would rather die and take the host with him. He convulses and collapses to the ground and his two guards, with a third Tok'ra present, open his cell to check on him. Though they are armed, specifically with weapons that are non-fatal and can be used even against a human shield, Tanith is able to grab one by the throat and escape. Perhaps because the writers could not think of a way to show this without having the Tok'ra appear completely incompetent, the scene cut away after he grabbed the first guard. O'Neill subsequently lampshades just how incompetent they must have been to let him escape.
When Teal'c has been brainwashed into once again serving Apophis, he captures O'Neill, Carter and Daniel and locks them in a room aboard a ha'tak, whereupon Selmak breaks them out because there were no guards stationed there...which was the entire point, since Teal'c wanted to capture Selmak, too, and needed an adequate lure. Apparently Teal'c is so badass that he actually is a competent guard.
In the Season One finale, to rescue Jack and Teal'c, Daniel takes Sam's sidearm and goes Akimbo while Sam uses the MP5. Later, he wields the Beretta M9 sidearm in one hand and the MP5 in the other. Granted, at that point he was just spraying and praying.
In "Seth", Jack, Sam, and Daniel do this with a pair each of zat'nik'tels.
In "200," Mitchell pitches a Zombie Apocalypse story that features him wielding two SMG's.
Teal'c has, throughout the series, operated two staff weapons and even two P90's. While this is never his standard equipment, when things get desperate he'll routinely pick up a second weapon (in the case of staff weapons, from an enemy Jaffa he's just killed) and wield both with great effectiveness.
Two episodes featured humans with Goa'uld DNA. The first was a harcesis, a child born of two Goa'uld hosts; the second was an experiment by Ex-NID operatives to gain access to the Goa'uld genetic memory.
The Serrakin — a race capable of breeding with humans despite not being Human Aliens. They had liberated the humans of their system from the Goa'uld millennia ago and the two species now co-exist in a mixed society.
Adria is a human with the knowledge of the Ori bred into her DNA. She is described as an Ori in human form, their way of getting one of their own into the Milky Way without technically violating the rules the Ancients have against directly interfering.
Hand Blast: The Goa'uld hand device, useful for energy pulse attacks and brain scrambling.
Hard Light: Merlin shows an extreme fondness for hard light constructs, using them as the guardians and tests of his various workshops. SG-1 has had to face two knights and a dragon in order to prove themselves worthy of his knowledge.
Aris Boch seems to have a change of heart, realizing that SG-1's fight against the Goa'uld is a worthy venture.
Harry Maybourne went from enemy to convicted US traitor to useful asset to grudging ally and friend. Eventually SG-1 even relocates Maybourne offworld to protect him from punishment for his original crimes.
Richard Woolsey, first an agent of Senator/Vice President Kinsey and the NID, then digs up information to incriminate Kinsey after getting a peek at his true nature. Notable for remaining a committed bureaucrat (though a relatively less obstructive one) after his change of allegiance.
Heel Race Turn: The Jaffa are the prime example, although due to the Kirk-like influence the team tends to have on certain worlds, there are certainly plenty of minor examples.
In "Bane," Dr. Timothy Harlow realizes mid-sentence that Colonel Maybourne is not just willing to take unscrupulous shortcuts, but is actually planning to let Teal'c be transformed, and that by calling him in for assistance he has doomed Teal'c to a painful death.
In "Inauguration," Mr. Woolsey begins to realize that his superiors might not be as honorable as he believed when his conversation with Vice-President Kinsey seems to end with the implication that Kinsey is going to assassinate the president if he does not get his way.
Heroic Resolve: Mitchell was badly beaten by Merlin's holographic knight in "Avalon," but was able to gain a new reserve of strength when he thought back to how he refused to give up after he was injured when his F-302 was shot down over Antarctica. Since the knight is more of a test than an actual enemy, he defeats it and gains access to the riches and technology of Merlin.
Heroic Sacrifice: Gerak knew that turning against the Ori would mean his immediate death, but still chose to help cure the Prior plague that was ravishing the Earth.
Lieutenant Colonel Cameron Mitchell starts season nine almost obsessed with working with SG-1. When he learns that he is actually going to be in command of the unit since all its prior members have been reassigned, he gets the band back together because he specifically wants to work with those three people.
Amanda Tapping was pregnant throughout the end of Season Eight, with her stomach hidden with the traditional practices of obstructing objects and dark, black clothing. She was on maternity leave when filming began for Season 9, leading to Carter being temporarily assigned to Area 51.
Lexa Doig became pregnant with her and husband Michael Shanks' second child during filming for Season 10, resulting in her character of Dr. Carolyn Lam having a greatly reduced presence and all but disappearing from the show.
History Repeats: "Spirits" revolves around a plan by the US Government to surreptitiously mine trinium from a planet inhabited by descendants of the North American Salish. When they learn of this, SG-1 is very upset over the repetition of the early history of the United States, and explicitly points out that we were supposed to have learned from our mistakes.
Honor Before Reason: The Ascended Ancients have as their primary philosophy a policy of non-interference amongst the lower planes of existence. They believe in this so strongly that they will not interfere when the Ori, their hated enemies who are planning their destruction, manipulate the lower planes in order to increase their own power, nor even when the inhabitants of the lower planes gain a weapon to kill Ascended beings. As Morgan Le Fay explains, if they interfere then they will be no better than the Ori.
Hostage Situation: In "Bad Guys," SG-1 is mistaken for a group of rebels on an alien planet and wind up taking a museum hostage. They realize that if they just let all the hostages go the military that surrounded the museum will storm in and kill them all, so they decide to hold on to the hostages until they can get the stargate working and gate off the planet. Unfortunately, the people in charge of the besieging forces seem to have no clue how to run a hostage negotiation, Daniel seems to have no clue how to play a hostage-taking terrorist, and there's a security guard who thinks he's John McClane, so Hilarity Ensues.
The Nox are woodland creatures that appear human with leaves and twigs in their hair. The reason why they look almost human is never explained.
The Jaffa are a genetic offshoot of humanity created by the Goa'uld. They are biologically human in most respects, except they have an abdominal pouch which is used to incubate larval Goa'ld; the Goa'uld larva in turn grants the Jaffa immunity from disease and an increased lifespan, but cannot be removed without killing the Jaffa.
Humans Are Special: Humans are not shown to be particularly smarter, stronger, faster or more "imaginative" than other species, but the Asgard point out that they have great potential.
"This form" is (rarely) used to refer to the general human species, to distinguish them from alien species. When the issue of the evolution of the Ancients and the subsequent identical evolution of humanity is raised, the term "this form" is used to refer to both Ancients and humans, since the technical issue of species classification is somewhat tricky.
Humorless Aliens: O'Neill is distrustful of the Aschen for precisely this reason. Also, Teal'c tends to miss the point of O'Neill's jokes. Funnily enough, the trope is also inverted in one episode; Teal'c, with prompting, tells a Jaffa joke that obviously amuses him, but falls flat on its face with the rest of SG-1.
The System Lord Yu has been punned so often that characters have actually put a moratorium on further punning, explicitly stopping others and explaining that it has all been done before.
When Ba'al begins cloning himself, Ba'al-related puns become quite common:
Cam: We've got a full count, sir. Two strikes, three Ba'als.
Hypocritical Humor: In "Cor-ai" Hammond says to Jack: "The US military is not in the habit of interfering with the affairs of other peoples." Jack just sort of looks at him and then at Carter and says, "Since when?"
I Can See My House From Here: Although in this case it is not to emphasize how high they are, but how relatively low they are getting.
I Can't Believe I'm Saying This: One of the funniest parts of this series is watching the Very Serious Military Personnel describing or giving orders in absurd situations.
Hammond: What am I supposed to say? (pulls out microphone) A glowing energy being is headed for Level 28. Lower your weapons and do not attempt to intercept it.
Hammond: Okay, people. Let me remind you. This mission is recon only. Do not engage the enemy. I'm allowing the use of this ship because of the obvious tactical advantage it provides you. Under no circumstances is it to be used to travel through time. (beat) Never in my life did I imagine ever giving that order.
Jack O'Neill: We came in peace. We hope to leave in one... piece.
I Did What I Had to Do: After Teal'c kills Sha're he is sad, but he points out that it was a choice between her life or Daniel's, and if he was in the situation again he would make the same decision.
I Die Free: Trope Codifier. Rebel Jaffa are frequently heard saying this when threatened by one of the Goa'uld or their followers, or in any other case where they're about to make an act of suicidal defiance.
IdiotBa'al: Pretty much everyone holds it at some point. Specifically, any Goa'uld (villain or not), any planet visited by a Prior of the Ori, and SG-1 from time to time.
If You Kill Him, You Will Be Just Like Him: In "Cor-ai," Hanno is prepared to kill Teal'c as soon as he sees him, but one of the other villagers convinces him not to go through with it and take Teal'c prisoner for cor-ai (trial). He explains that if Hanno kills him in vengeance, then they will be no better than the Jaffa.
I Gave My Word: In "Spirits," T'akaya agrees to hear out Daniel and Jack if they show her where Xe'ls is. When Xe'ls awakes he orders T'akaya to destroy the SGC, but she refuses until she has at least heard them out; Xe'ls points out that they have already learned of plans by the SGC to deceive them and that their word is worthless, but T'akaya still refuses to act, pointing out that her word would be worthless, too, if she broke her own promise.
"I Know You're In There Somewhere" Fight: Often when talking to a loved one who has been taken as a host. A recurring question in early episodes was if there is any part of the host's mind/soul that survives. There is, and the Goa'uld just suppresses it. At least in the case of a young symbiote with a strong-willed host, it is even possible for the Goa'uld to momentarilly lose control.
I'll Take Two Beers Too: When the team is under the influence of appetite-increasing phlebotinum.
I Made Copies: When General Hammond gives Mr. Woolsey a computer disk with evidence to incriminate Vice-President Kinsey in a conspiracy of blackmail and murder to gain control of the stargate, he points out that it is not the only copy before Woolsey even asks.
Impossibly Mundane Explanation: In "Window of Opportunity" Jack has prior knowledge of a briefing Carter is giving and claims that he is remembering things from the future. Carter suggests, "Maybe he read my report?" Daniel gives her a skeptical look and repeats, "Maybe he read your report?" as if it was the most ludicrous suggestion. Everyone else (O'Neill included) seems to agree.
Impostor Exposing Test: In "Foothold", Maybourne cuts himself in front of Carter to prove he's human after an alien impostor is shown to have purple blood.
Impaled Palm: O'Neill inflicts this on Heru'ur in "Secrets".
Dr. Felger is unsure if O'Neill knows he is there when he calls him a "brown-nosing little weasel." His tone makes it clear that he does not know which answer he would prefer: That O'Neill is talking about him behind his back, or that O'Neill is directly insulting him to his face.
Vala continuously refers to the SGC's attempts to understand the Goa'uld bracelet bond as pointless, to which Dr. Lee, who is running the tests, points out that he is actually touching her face at the time.
Incoming Ham: "Urgo", featuring Dom DeLuise. Just watch the background characters trying desperately to keep a straight face.
Inconvenient Summons: The Asgard love getting a hold of O'Neill this way. Frequently in mid-sentence.
Incredibly Lame Fun: When Jonas Quinn arrived on Earth he became fascinated by the Weather Channel and watched it for hours, to which Carter responds that here are at least five hundred other channels.
Incredibly Lame Pun: The System Lord Yu's name is frequently punned by the humans due to its similarity to the English word "you." When Dr. Elizabeth Weir, who was only learning of Yu for the first time, began to make her own pun, Daniel explained to her that every possible variation had been done to death, and it was no longer funny.
Infinite Supplies: Averted. The inability of the rebel Jaffa to even feed themselves is a recurring problem, as is their lack of weapons and supplies to wage their war. The Hak'tyl, a group of female Jaffa from the domain of Moloc, seek out an alliance with the SGC and offer their services as soldiers, scouts and spies in return for food and support.
In Harm's Way: Carter is a real adrenaline junkie in her spare time, and volunteers to take part in a dangerous alien competitive spaceship race in "Space Race."
Inkblot Test: When Vala is being examined for suitability to formally join the SGC, the reviewing doctor has her look at blots, but stops when she tries to game the system by saying that she sees abstract concepts, like 'courage', in the blots.
Insectoid Aliens: The Reetou, which are invisible to the human eye but can be sensed by a Goa'uld symbiote.
Insignificant Little Blue Planet: It turns out Earth played an integral role in the history of the universe, but for the present day and the past few millennia it has been little more than a backwater planet forgotten by the more advanced races.
Instant Sedation: Averted more often than it is played straight.
In "In The Line of Duty", when Sam/Jolinar gets tranqued twice, the first case with "enough to knock out an elephant," it takes a minute before she is disabled.
"Spirits" is the one episode where it is played straight; SG-1 is incapacitated by small darts towards the beginning of the episode and collapse almost immediately after being shot.
Osiris is twice shot by a Goa'uld-specific sedative, and in both cases it takes several minutes before it takes effect. In "The Curse" he even managed to make good his escape before succumbing to the drug.
In "Memento Mori," Vala is injected with a sedative directly into her carotid artery, and she ''still' does not lose conciousness right away. She becomes unsteady on her feet and unable to talk, and is rushed into a vehicle by her kidnappers.
Interdimensional Travel Device: The Quantum Mirror, which makes a few appearances in early episodes before being destroyed offscreen. In one episode, Daniel accidentally uses it to travel to another universe; in a later episode, alternate-universe versions of Carter and Kowalski come back through it, looking for refuge from the Go'a'uld invasion fleet that just arrived on Earth in their universe.
In "Bane," Ally Martin discovers and helps hide the poisoned Teal'c after he escapes from NID custody. Once he is healed, he returns and gifts her a new super soaker.
In "Learning Curve," Teal'c gives Tomin knowledge of the Goa'uld to help defend his society, and becomes almost violent when he is told that Tomin cannot return and suspects that he has been mistreated.
Interservice Rivalry: Between the SG-3 Marines (Jarheads) and the SG-1 Air Force (Flyboys) after the former's introduction in "The Broca Divide." It is brief and does not appear in subsequent episodes.
In the Back: Colonel Simmons shoots O'Neill in the back in the climax of "Desperate Measures."
Invisible President: The President of the United States during the show's first seven season, stretching from 1997-2004, was unidentified either by name, image or party.
I Resemble That Remark: Carter's response to being told that she seems tense is to, very tensely, reply that she is not tense.
It's All About Me: In "2001," Senator Kinsey genuinely believes that O'Neill is willing to sabotage Earth's alliance with the Aschen, which could potentially save the planet from the Goa'uld, all in order to prevent Kinsey from becoming President of the United States.
Daniel Jackson joined SG-1 because his wife, Sha're, and brother-in-law, Skaara, had been taken as Goa'uld hosts. Throughout the series numerous other loved ones are killed or implanted by the Goa'uld.
Teal'c worked so hard to become First Prime of Apophis because Cronos, enemy of Apophis, had killed his father and he wanted to be in a position to exact vengeance. He later swore a "Jaffa revenge thing" against Tanith, the Goa'uld that lied to, betrayed and killed Shau'nac, his childhood love interest.
When O'Neill gets upset at Felger's statement that there are "only" a dozen Jaffa for SG-1 to fight their way through, Felger points out that this is what SG-1 does. The whole team pauses for a few seconds before apparently agreeing and moving on.
In "Zero Hour," when O'Neill mocks Ba'al as he always does, his new aide asks if it is necessary to actually provoke him. O'Neill simply turns to him and says "it's what I do."
Jailbait Wait: When Orlin descends for a second time, he takes the form of a young boy instead of the grown man he was in season five. He explains that he knew this would cause problems for his relationship with Carter, since he was aware that human societal mores disapproved of a relationship between a grown woman and a child, and hopes that they will be able to resume their relationship in a few years. Carter is unnerved by the entire discussion.
Jimmy Hart Version: The dance scene at Mitchell's reunion in "Bounty" has several. When he dances with his old flame it is a pretty blatant Jimmy Hart Version of "Can't Fight This Feeling" by REO Speedwagon.
The John Henry: Stargate SG-1's humans, who firmly believe that good old-fashioned Earth bullets work better than Goa'uld weapons. They get their chance to prove it once the Replicators enter the scene. That and guns are easier to shoot than a staff weapon. Jack later demonstrates to rebel Jaffa that their weapons are superior, and describes the Goa'uld weapons as "a weapon of terror" made to scare, while the P-90 is "a weapon of war" made to kill.
Averted in "Touchstone," where Hammond explicitly points out that, since the NID facility officially does not exist, there is no jurisdiction conflict to prevent SG-1 from apprehending its personnel.
In "Seth," SG-1 believes that the titular Goa'uld has been hiding on Earth since the Stargate was buried in ancient Egypt and investigate a cult led by Seth Fargough to see if he is the Goa'uld in hiding. They bump into the Bureau of Alcohol, Tobacco and Firearms which has been monitoring the cult due to its traditionally illegal cult activities (including possession of illegal firearms, rumors of killing dissenting members, etc.) and the ATF refuses to allow the USAF to participate. O'Neill calls the president and has him appoint SG-1 to the operation.
In "Wormhole X-Treme!" Carter and Daniel are led to an NID staging ground by their target, who hopes to delay both organizations. Once they have figured out who is who, Carter states that she plans to accompany the NID, but Agent Barrett explains that the NID has been given complete authority in this investigation and will not share it with the USAF.
In "Uninvited," the Air Force takes over an investigation from the local sheriff when they determine that the bear that has been killing local hunters is actually a dangerous creature that they inadvertantly created. They stick with the 'bear' story, of which the sheriff is understandably skeptic since they explain that it is a matter of national security but he never gets a chance to dig deeper since the creature kills him at the end of the scene.
Kangaroo Court: "Cor-ai" featured Teal'c being put put on trial for killing a man while he was still serving Apophis. The twist was that his prosecutor was the son of the man he killed, and was also the judge and jury. Jack greatly complains about this, only for Daniel to say that this has historical precedent. Which just pisses Jack off.
Kicked Upstairs: After General Landry settled in at the SGC he realized that most of the meetings he had to go to were basically pointless and orders Sergeant Walter "Chevron Guy" Harriman to go in his stead. When Walter protests, Landry threatens to promote him if that is what it takes.
Killed Off for Real: Major Kawalsky, Sha're, Martouf, Apophis, Narim (and the rest of the Tollan), Janet Frasier, Jacob Carter, Colonel Pendergast and the Prometheus, and the entire Asgard race. Abydos is destroyed and everyone on it is killed, but they are Ascended to a Higher Plane of Existence.
Killed to Uphold the Masquerade: Maybe. A reporter with information on the Stargate Program is killed in a car accident mere seconds after O'Neill fails to convince him not to run the story, but O'Neill claims (and is assured by General Hammond) that the Air Force had nothing to do with it.
Kinetic Weapons Are Just Better: Played straight; most characters use SMGs or handguns for the whole series and even Teal'c trades in his staff weapon for a P90 (or two) in the last three seasons.
King Arthur: Seasons nine and ten delve deeply into Arthurian legend, with the revelation that Merlin was an Ascended Ancient who retook human form in order to build a weapon to fight the Ori. Though Arthur himself never appears, SG-1 does visit Camelot and follows in his footsteps to look for the sangraal, the Holy Grail, which they believe to be the weapon that Merlin built.
The Kirk: More often than not, Samantha or Daniel.
Kissing Under the Influence: In the first season episode "The Broca Divide," before the heavy Ship Tease began between O'Neill and Carter, Carter attempted to force herself on O'Neill when she began to regress into a primitive being. It was not a funny scene.
Klingon Promotion: In "Bounty," SG-1 points out that Netan's position in the Lucian Alliance is extremely tenuous and that if somebody managed to kill him they could probably take over the entire organization.
Knighting: In "Theads," Teal'c and Bra'tac are dubbed "blood-kin to all Jaffa" in recognition of their work in the overthrow of the Goa'uld, tapped once on each shoulder by a staff weapon.
Knights Templar: Plenty, but particularly the rogue NID, which became the Trust.
Lampshade Hanging: Frequently, often pairing up with Genre Savvy (see above); and forms the basis for much of the series' humour; particularly when Colonel Mitchell (Ben Browder) joins the cast. The episode "200" lampshades tons of tropes from sci-fi and movies in general to the show itself, including the act of Lampshading!
La Résistance: Season five's "The Warrior" saw the formation of an official, organized Jaffa resistance to the Goa'uld, founded by K'tano, former First Prime of the minor Goa'uld Imhotep that killed his ruler after he was inspired by Teal'c's example. K'tano was eventually revealed to be Imhotep, and was killed by Teal'c in ritual combat for leadership of the rebellion, but the organization continued and eventually become the Free Jaffa Nation after the overthrow of the Goa'uld in season eight.
Large Ham: The Goa'uld have a habit of this for various reasons. Rodney McKay lampshades it in "Redemption, Part 2" after Anubis tells the SGC they're all going to die at the end of Part 1:
McKay: Hello, Anubis, this is your agent. You're playing it way over the top; could you please tone it down?
Laser-Guided Amnesia: "Fire and Water", "Beneath the Surface", "Fallen", "Revisions", "Collateral Damage", "Memento Mori".
Law of Inverse Fertility: In the alternate timeline of "2010", Carter and her husband Ambassador Joseph Faxon are trying very hard to have a child, but so far are unsuccessful thanks to the Aschen.
Layman's Terms: Frequent. Especially whenever Daniel or Sam try to explain something to O'Neill. Whenever O'Neill uses a technical term himself it is usually cause for a double take from the other characters.
Leaning on the Fourth Wall: The episodes "Wormhole X-Treme!" and "200". Also, this gem of an O'Neill quote:
Local:(about Teal'c) He is Jaffa! O'Neill: No, but he plays one on TV.
Left It In: In the "documentary" made about Wormhole X-Treme! at the end of "200," Martin Lloyd stops his interview to take a phone call, during which he is quite profane, and then goes back to talking about how much of a family the crew is after checking to make sure that they had not recorded his previous comments.
Lensman Arms Race: The SGC goes from a platoon-sized group of special forces going through a star gate they barely know how to operate, to a small fleet of interstellar star ships, in about eight years.
Let's Split Up, Gang: Daniel lampshades it when the Russian Major he is trapped in a Goa'uld ziggaurat with leaves to explore the hallways and tells Daniel to wait there; commenting that both of them will be alone in a dark and dangerous maze.
Let Us Never Speak of This Again: The season one episode "Hathor" was heavily disliked by both fans and the producers, and in following episodes the characters mention that they have agreed to never talk about it again. True to that, the specific events of the episode are never revisited, with characters only talking about the "Hathor incident" without saying what actually happened.
The Toka'ra have a lie detector which works via mind reading. Instead of actually reading if a character is being truthful or lying, it reads their conscious and unconscious thoughts and compares them, to see if their recollections match what they are saying. It is used to detect a zatarc, a person that the Goa'uld have brainwashed into an assassin and then covered up their brainwashing with false memories.
Vala is given a polygraph when she is being reviewed for suitability to formally join the SGC. Its use is in line with most flawed depictions of the polygraph, indicating that Vala is lying when she tries to complement the doctor and noting each successive lie when she tries to cover herself.
Like Reality Unless Noted: Unless the show outright says so, what's happening outside of the Stargate program is the year that particular season was produced.
Long Game: The Aschen as a whole are a very patient race, and conquer other planets over the course of centuries. Their standard operating procedure seems to be forming an alliance with the current government and granting them superior technology in order to gain their trust, but slowly reducing their population by inducing wide-spread infertility through their medical treatments. After several centuries the planets inhabitants will be too few to prevent the Aschen from assuming complete control.
Long Runners: Stargate: SG-1 ran for ten seasons and a total of 214 episodes, with two additional DVD movies, and was followed by twospinoffs.
Daniel gets away with helping the Tollan escape because, as a civilian, he cannot be court martialled, and he could not be tried in civilian court without revealing the Stargate Program.
In another episode, one of the Nox helps the Tollan defend themselves by hiding one of their planetary defense turrets so it is not destroyed by the Goa'uld. When Carter calls her out on doing this despite her people's dedicated pacifism and neutrality, she remarks that she only hid the weapon — she did not fire it. Carter remarks that that is a pretty fine line she did not cross.
In "Lockdown," O'Neill is complaining about his recent promotion to general, particularly about the pressure he is under to appoint a new member to SG-1. When he explains that he wants to keep it like it is, as a three-person team, Carter points out that there is no rule that says SG-teams have to have four members, and O'Neill latches on to that rationale as a way to avoid making the decision.
Lost Superweapon: When Earth is under the threat of a massive alien invasion and if the usual tricks and weapons did not work, there is the ancient outpost in Antarctica, whose chair can control and launch thousands of powerful drones, only requiring a humongous amount of power. Surprise!
Lost Technology: Lampshaded by Colonel O'Neill in a Season 6 episode where the Human Aliens have no artifacts from the Goa'uld.
O'Neill: That's weird. The Goa'uld are damn litter bugs, they leave all kinds of crap lying around.
Love At First Mind-Meld: Orlin falls in love with Carter the very instant he meets her, but he tries to justify it by explaining that Ascended beings can join their essences to another person and understand them on a fundamental level right away. Carter is skeptical and, even though she warms up to him eventually, never does fall in love with him in return.
Luke, I Am Your Father: Wonderfully played with and torn to shreds during the 200th episode. For a moment, you almost believe...!
MacGuffin Delivery Service: At the climax of "Wormhole X-Treme!" Teal'c rescues O'Neill and Martin from Tanner and the three of them return to the studio to retrieve the control that Martin had hidden...which was exactly why Tanner had left them unguarded for Teal'c to save.
In the pilot episode, Carter refers to control computers for the Earth Stargate as a MacGyvered device, which was something that actress Amanda Tapping had ad-libed during her audition.
When O'Neill, the original, has advanced Ancient knowledge transplanted into his brain he builds many advanced devices out of equipment he finds lying around the base, sometimes without even knowing what he is building.
When the descended Ancient Orlin crashes at Carter's place, he builds a way to make precious gems and a functioning stargate from household parts and some special order supplies.
Averted: Not once in the entire series does the use of a defibrillator restart somebody's heart after it has stopped. In fact, not once in the entire series does a defibrillator do anything: The patient either heals on their own before the paddles are applied, heals on their own after the paddles have failed, or simply does not heal at all and dies.
Mama Bear: When Cassandra is in danger, Dr. Fraiser becomes somebody you do not want to mess with. In one episode, Nirrti is being held at gunpoint by her to help Cassandra, and refuses—until General Hammond points out the Doc's relationship with the girl.
Masquerade: The World Is Not Ready. At several points in the series different factors prompt the government to decide that it is time to reveal the truth, only to change their mind once the situation changes.
In Small Victories. When Thor's Replicator-infested ship is about to descend into Earth's atmosphere, it is said that the President is going to reveal the existence of aliens and the Stargate to the world if they can't shoot it down.
When the Stargate Program is revealed to the UN Security Council they explain that they are going to reveal the truth, but decide to hold off when Thor arrives and explains what a good job the SGC has done.
Maybe Magic, Maybe Mundane: In "Grace," Carter spends the episode conversing with hallucinations of the members of SG-1, her father, and a mysterious young girl; at different points the hallucinations say they might be a manifestation of the nebula that might be sentient and trying to comunicate with Carter, or they might just be normal hallucinations caused by her head wound and lack of sleep. The episode ends with no concrete explanation either way.
The McCoy: Jack would often drop the sarcasm to be genuinely concerned about the episode's moral plight... or bug Sam and Daniel incessantly about why they could not be Big Damn Heroesthis episode.
Prometheus. The Greek Titan Prometheus stole fire from the gods to give to man; the Prometheus project used technology stolen from the Goa'uld to create Earth's first battlecruiser. The Prometheus itself is destroyed in the episode "Ethon", which is the name of the eagle that ate Prometheus' liver every night in some versions of the Greek myth.
The planet where Janet Fraiser is killed is identified as P3X-666.
Medieval Stasis: Some of the Transplanted Humans have developed their own unique societies, culture and technology descended from the peoples they were before being taken off Earth, but more planets have remained completely unchanged from their technological and cultural status five thousand years ago. The Asgard Protected Planets Treaty addresses this point with regards to planets that the Goa'uld have agreed not to conquer, deliberately limiting their development so they do not become a threat.
Meet the New Boss: The Ori, the replacement Big Bad after the defeat of the Goa'uld in season eight and the Re Tool of the show for season nine, replicate the modus operandi of the Goa'uld: The impersonation of gods in order to inspire worship and subservience. The difference is simply one of scale: The Goa'uld used advanced technology for their masquerade, whereas the Orio really did have god-like powers.
Men Are the Expendable Gender: In "The Tomb," three of four Russians sent offworld are killed, with the only survivor being the single female officer.
Mental Story: "Avatar" takes place in a virtual-reality scenario that's effectively going on inside Teal'c's head.
Merlin: Season nine reveals that Merlin was an Ascended Ancient who descended to mortality in order to build a weapon to use against the Ori. In his first life he was Moros, who was the last High Chancellor of Atlantis, and after he returned to mortality he was known as Myrddin, the name of the Welsh wizard that much of Merlin's mythology is based on.
Me's a Crowd: Ba'al developed cloning technology in season nine, creating dozens of other Ba'al's to help him reclaim his power after the overthrow of the Goa'uld.
Metaphorgotten: Dr. Lee tries to think up a clever analogy for how hard it will be to develop an anti-Prior weapon, but cannot even start before he trails off into Buffy Speak. He and Carter laugh at his failed attempt, and he explains that he has not had a chance to sleep recently.
M.I.B.: NID, who start out as a sometimes-antagonistic, sometimes-allied "The Ends Justify The Means" civilian counterpart to the SGC, but later lose the antagonistic aspects once the shady leaders, after being exposed, go underground to form a different group.
Mildly Military: Present in every show in the Stargate Verse to some degree. According to General Michael E. Ryan, Chief of Staff for the Air Force (the real Chief of Staff for the real Air Force), he has subordinates who are much worse than O'Neill in real life.
The Goa'uld have a memory recall device that can read a persons mind and portray their memories on a screen for others to see, and it can help the subject recall suppressed or forgotten memories, but its use in interrogation is (Relatively) limited since it can only display memories that the subject wants displayed. This forces the Goa'uld to go through the standard methods of torture and questions before they can bring up the desired memories.
When Anubis appears in season five, he brings advanced technology that allows him to download knowledge from a beings mind directly into his ships computer, bypassing the slow and ineffective torture preferred by most Goa'uld. Unfortunately for Anubis, the first being he tries this on is Thor of the Asgard, whose brain is so powerful that he manages to take control of the ship through his link to the computer.
In the season 1 episode Fire and Water, SG-1 is implanted with a fake, traumatizing memory of Daniel Jackson's horrific death.
The human form Replicators explore human minds to learn their secrets in an excruciating process, and Fifth does it purely to cause pain.
Mistaken for Gay: Briefly in the opening to "Crusade;" before the body-swap is explained, Mitchell notices Daniel ogling him wearing only a towel in the locker room and asks if there is something he should know.
Mook Horror Show: When SG-1 is attacking the Jaffa guarding the stargate in "The Other Guys," O'Neill, Carter and Jonas use the standard "shoot them with zats" approach, but Teal'c instead waits for a Jaffa to run past him and erupts out of a lake and drags the Jaffa down into the water.
Moral Dissonance: Early on, Daniel kills a vatful of Goa'uld larva before the team knew they were Always Chaotic Evil. Carter tries to dissuade him before he actually does it, but afterwards nobody seems to care that he just slaughtered a jar of babies that, for all they knew, could have been perfectly sweet and friendly.
Mr. Exposition: Daniel for the culture and Carter for the science. Whenever one of them is missing, the other tends to fill in anyway: any bit of Imported Alien Phlebotinum will have both "Goa'uld language" and "strange radiation". Jonas is a physicist (with a Photographic Memory) who has studied every single one of Daniel's notes, so he can be either too, though Jonas is usually The Watson during briefings. Even Teal'c can fill this role (though more often in the early seasons), usually in a context of "Yes, I encountered this race/weapon/artifact/person while serving as First Prime to Apophis, and I will now tell you all about it."
Mud Wrestling: In "Ascension," O'Neill and Teal'c head to Carter's place with pizza and a movie, and when they learn that she has company they leave her the pizza and decide to have their own fun. Teal'c comments that he has heard of place "where humans do battle in a ring of jello," and O'Neill tells him to call Daniel.
Mundane Object Amazement: When Jonas Quinn comes to earth, he is fascinated by the Weather Channel and the way it provides the weather for the whole planet, and explains that the five-day forecast feels like predicting the future.
Stargates are one of the most advanced technological devices in existence, able to create a stable, people-safe wormhole across a galaxy or even to other galaxies. In the Groundhog Day Loop episode "Window of Opportunity" Teal'c and Jack hit golf balls through the gate, which the writers had wanted to do for the entire series.
The Asgard's teleportation technology can transport anything from anywhere to anywhere else. It has been proven to be able to dematerialize enemy structures and platoons of Jaffa in seconds the first time they are shown. The Asgard use this in lieu of walking, simply teleporting themselves and the chair they sit in to the relevant destination.
My Greatest Failure: Colonel Mitchell has two past mistakes which still haunt him.
In "Collateral Damage," Mitchell reveals that he once bombed a refugee convoy on Earth after he was told by his commanding officer that it contained enemy combatants; the order to abort the mission came seconds after he had released his payload.
In "Stronghold," though the precise details are never revealed, it shows that before Mitchell joined the F-302 program he did something extremely reckless that another pilot, and close friend, had to rescue him from. The other pilot was wounded by shrapnel during the rescue and was therefore disqualified from joining the F-302 program, and Mitchell was granted his spot in his place. Mitchell believes that he is unfairly living the other pilots life, and blames himself for the life-threatening aneurysm that has been threatening the other pilot since he was wounded.
Myth Arc: Stargate Command had a mission statement, enumerated in the pilot episode: to defend Earth from aggressive aliens, explore space, and acquire alien technology. In almost every season they made tangible progress toward those goals. At the end of the first season they had recruited Teal'c, befriended his mentor Bra'tac and discovered vague information about several other potential allies out there, by the end of the fourth they had made permanent allies of the Tok'ra and Asgard and claimed enough Goa'uld hand weapons to outfit their own teams, and by the end of the sixth season they had stolen, discovered or reverse-engineered enough technology to build an interstellar spaceship on Earth.
Neglectful Precursors: The Ancients left a lot of their technology lying around when they left the Milky Way, including some weapons and society-shaking devices, without any adequate instructions or explanations. The technology which was the instructions, the Repository of the Ancients which had all their knowledge, did not have any labels for itself. It is only identified as "The Place of Our Legacy," and without using it (and potentially dying from its use) there is no way to determine what that means. Of course, considering they "left" the Milky Way by dying en masse, with the survivors fleeing a wide-spread plague, it might be a bit much to expect them to have left a notebook behind.
In "Grace," the hallucination (maybe) of Teal'c explains to Carter that she is suffering from a concussion and that if she goes to sleep she will die. Throughout the episode her perception of time is radically skewed, and she has suffered a blow to the head, so she struggles to stay awake over what seems like weeks.
The episode "Morpheus" involves a microscopic insect (Not a bacteria) that causes the human body to produce high levels of melatonin, causing an almost irresistible urge to go to sleep, and once asleep to keep you asleep. Once you are asleep the insect gorges itself on the melatonin, growing in size until it kills by causing a brain aneurysm.
O'Neill getting an Ancients' databse downloaded into his brain, twice, after which he subconsciously builds things and goes places without understanding why.
In "Secrets," they learn that a Goa'uld that inhabits a pregnant woman remains dormant so as not to cause a miscarriage, and the host can access the knowledge of the symbiote during this time.
Never Heard That One Before: When Dr. Weir is about to make a Yu related pun in "New Order," Daniel explains that every possible variation of the joke has already been done.
In the climax of "Thor's Hammer," the team destroys the titular device in order to save Teal'c's life; in the follow-up episode "Thor's Chariot" the planet has been invaded by Heru-ur because it now lacks any defense.
The Tok'ra interpretation of humanity's influence on the Goa'uld balance of power. By killing off important System Lords, the Tau'ri have systematically allowed more dangerous Goa'uld to usurp the power vacuum, including Sokar, Anubis and Ba'al.
In the beginning of season eight, Thor and the SGC finally gain a weapon that is effective against the Replicator's on a large scale. In "Gemini," they study RepliCarter and inadvertantly let her near the weapon long enough for her to learn how it works and develop a countermeasure to the device. Carter spends much of "Reckoning" blaming herself for the Replicator's subsequent invasion of the Milky Way.
In "Icon," the nations of Rand and Caledonia had ben locked in a Cold War for years, but when the SGC makes contact with the planet the balance is disrupted by religious extremists who manage to gain power when the activation of the stargate "proves" that their religious views were correct. Their attempt to seize control of the Rand Protectorate sparked off the long-feared war with the Caledon Federation, decimating the entire planet, and many blame the SGC for sparking the conflict. At the closing of the episode, Jared Kane admits that the war wasnotthe fault of the SGC, as the two states had been on a collision course for years and would have destroyed themselves eventually.
The Ori arc in season nine begins when Daniel Jackson and Vala Mal Doran inform the Ori that there are humans in the Mikly Way that have been shielded from them by the Ascended Ancients. Daniel in particular realizes that they have potentially just doomed the galaxy to subjugation by the Ori, and that it is their fault.
In "Uninvited," the SGC discovers that it was their modifications to the Sodan armbands that created the giant, vicious creatures that have begun killing innocent people on three planets (Including Earth).
No Good Deed Goes Unpunished: Orlin got a particularly raw deal when he descended to a mortal form in order to provide valuable intel on the Ori and helped to develop a cure for the Prior plague. For his troubles, he not only became trapped in his mortal form, but also suffered permanent brain damage, consigning him to spend the rest of his life (which is considerable, as he came back as a 12-year-old boy) in a sanitarium.
No Gravity For You: Does not appear in the show proper, but rather the Show Within a Show that is made about the Stargate crew. Such elaborate tactics are unnecessary in the regular series since they, you know, they have guns.
Nom de Guerre: Cameron Mitchell was given the call-sign "Shaft" when he was an F-302 pilot stationed aboard the Prometheus. Off Carter's look, he explained that it came from the term "camshaft", which is a mechanical part that resembles the shortening of his first name.
No Name Given: The Ancients. While they are given many epithets during the series, such as the Ancients, the Ancestors, the Gate-Builders, the Lanteans etc... we never find out what the species true name was. The Ark of Truth claims they were once named "The Alterans", but even that equates to "The Others", which is what they were to the Ori, whom they broke away from.
Noodle Implements: In "The Ties That Bind," part of Vala's Chain of Deals involved the exchange of an old plasma coil from a obsolete cargo ship for an old necklace. She needed to return the necklace to the man she stole it from, but she had no idea why the man who had it wanted that plasma coil.
In "Emancipation", the first "regular" episode of the series after the pilot and follow-up episode, O'Neill referred to an incident where Captain Carter drank something which made her take off her... something. We never do hear the full story.
Daniel asked Jack a question before the start of "Window of Opportunity," and his asking Jack's opinion of the question is repeated numerous times throughout the episode, but not even Jack himself can remember what he was actually talking about.
Anubis was originally expelled from the System Lords for crimes that even the Goa'uld found unspeakable. Considering that the Goa'uld are not just okay with, but routinely practice torture, slavery and genocide, the specifics of something horrifying them was probably too much for the writers to actually think up.
In "Stronghold," Mitchell and an old friend of his discuss a misadventure from before Mitchell joined the F-302 program where Mitchell did something reckless that required the other pilot to rescue him, during which he was wounded by shrapnel. What this was and where it took place were never revealed.
"200" mentions, and includes brief "flashbacks" to, an incident that left O'Neill invisible, although the canonicity of the entire episode is debatable.
No One Gets Left Behind: Practically the motto of the SGC, particularly O'Neill, who was left behind by his team during the First Gulf War and spent several months in an Iraqi prison because of it. It comes back to bite him when he bonds with a Tok'ra symbiote and it feels compelled to use him to go back for someone it used to spy on Ba'al, and we all know how that relationship is defined.
The 'kawoosh,' the unstable vortex of an opening stargate, will vaporize any matter that is caught within it, shoots out in the blink of an eye and covers over a dozen square feet. Stargates have no warning signs, no barriers built into them, or any device to suppress or weaken the kawoosh. The SGC installed the iris, which can suppress the kawoosh, but only when it is closed, and they usually open the gate with the iris open.
Most Goa'uld technology.
Daniel: You'd think a race advanced enough to fly around in spaceships would be smart enough to have seatbelts.
The President of the United States from the show's first seven seasons, 1997-2004, was never seen, and his party was never given.
The seventh season took place in the lead up to the 2004 Presidential Elections, with recurring villain Senator Robert Kinsey as the Vice-Presidential candidate with running-mate Henry Hayes. The ticket they were running on was never revealed, with the only information given about the election returns that Kinsey helped them win Florida.
No Such Thing As Space Jesus: Only brought up once. On finding a medieval-European style town on a planet, complete with church, cross, and witch-burning minister, Teal'c says that he knows of no Goa'uld that is capable of the love and compassion displayed by the Christian god. Turns out that episode's Goa'uld was impersonating Satan instead.
Nothing Is the Same Anymore: In the season six episode "Disclosure," the Stargate program and all related information is revealed to the United Nations Security Council (The United Kingdom, France and China. Russia was already aware of the Stargate) for the first time. For the rest of the series, and continuing into Stargate Atlantis, international political pressure is a frequent concern of the SGC.
Nothing Personal: Richard Woolsey is working to get the command staff of the SGC removed, and perhaps even brought up on charges, because he honestly believes that they are doing a poor job of defending the planet, not because he has anything against them on a personal level. When asked if he believes that O'Neill and Carter are engaged in some sort of inappropriate relationship he begins to deny it, only to be interrupted by Vice-President Kinsey who insists that they are. Woolsey is flustered by the unwarranted personal attack.
Not Me This Time: After Carter has been kidnapped, Maybourne recommeneds that O'Neill look into Colonel Simmons at the NID. Simmons, however, explains that he had no part in this, and points out that Maybourne might have been part of the operation himself. Simmons does get involved at the end of the episode.
Not Now, Kiddo: Played for Drama in the backstory episode "The Gamekeeper". The revisiting of events happens the same way as the original because Daniel's parents will not listen to him.
The first season episode "Emancipation," the first episode after the initial plot of the pilot, took place on a world where descendants of the Mongols have created a complicated system of laws restricting womens freedoms, ostensibly to protect them by keeping them hidden from the Goa'uld. They are forbidden from unveiling their faces or speaking outside of their tents, and are subject to stoning if they break the laws. The episode was criticized for its generally inaccurate depiction of Mongol society, although it did get some points for having Shang Tsung as the villain.
The Goa'uld Moloc decreed prior to the start of the series that only male Jaffa in his domain would be allowed to live, sacrificing all female children born in order to make sure that his society is solely devoted to giving him soldiers in his war with the other Goa'uld. The Jaffa as a whole have a heavily patriarchal society; women, though trained in combat, are forbidden from actually serving in the army of their ruling Goa'uld and are viewed as subservient to their husband. These traditions, referred to as the "old ways," are maintained even after the overthrow of the Goa'uld, and multiple episodes deal with Teal'c and other progressive Jaffa attempting to reform Jaffa society into greater equality.
Anubis was portrayed by a total of five actors over the course of the show, reflecting different hosts that he possessed and his incorporeal form. These were David Palfy (Who provided the voice and body of the robe-shrouded incorporeal Anubis up to "Lost City"), Gavin Hood (Who portrayed Russian Colonel Alexi Vaselov, whose body was possessed by Anubis), Dean Aylesworth (A nameless host), Rik Kiviaho (A nameless host) and George Dzunda (Who portrayed "Jim," the form Anubis took when speaking to Daniel Jackson in the Astral Diner).
When Orlin descended for a second time in season nine, he took the form of a young boy instead of a grown man in order to retain his Ascended memories for a little bit longer.
Nuclear Weapons Taboo: The episode "Icon" and its sequel "Ethon" takes place on a world where the two main powers, Rand and Caledonia, are locked in a state of Cold War technologically equal to 1950's Earth. Though both episodes eventually descend into full-scale war between the two powers, with the complete destruction of all infrastructure and the decimation of the planets population, none of the weapons are ever referred to as 'nuclear'. They are instead just called "missiles" and "bombs," without any specifics.
Obfuscating Stupidity: O'Neill constantly makes snide comments, is obsessed with The Simpsons, and has little to no patience for technical jargon. However, several characters over the course of the series outright make the observation that he is smarter than he pretends to be. It seems to be more that, as a career military man, he simply wants to know what the dangerous piece of alien technology will do and not how it will do it.
Off to See the Wizard: "200" included a complete retelling of The Wizard of Oz with Vala as Dorothy, a "lovely, fair-haired Tok'ra" (Carter) as Glinda, a wise Ascended being (Landry) as Oz, and Mitchell, Daniel and Teal'c as the Scarecrow, Cowardly Lion and Tin Man (Respectively). Martin Lloyd, who the story was being told to, immediately pointed out that it just was the original movie with stargate names replacing the originals.
Heru'ur when Apophis' cloaked fleet of Ha'taks uncloaks near the end of "The Serpent's Venom".
Daniel when shooting Vala in a Kull warrior suit does not do any damage.
When Daniel manages to get the anti-Prior device working, the expession on the Prior's face is about what you would expect when somebody feels that they have just been personally and directly abandoned by their gods.
Unless it is a question of archeology or linguistics (Daniel Jackson's area), advanced medicine (the unit's medical staff handle most of that) or midwifery (... that would be Daniel again), Samantha Carter has it covered on science.
Dr. Bill Lee, the SGC's second-fiddle scientist after Carter, seems to have studied every field. He is consulted on matters of physics, electrical engineering, botany and even entomology (The study of insects). He is rarely competent during these consultations, since his character is slight comic relief that is often Entertainingly Wrong, but he apparently has some training therein.
Only a Flesh Wound: Teal'c, frequently. In fact just about any wound Teal'c suffers is brushed off, lampshaded or not. Justified early, because he has a Goa'uld symbiote to heal his wounds at a rapid rate. However once the symbiote is removed and he survives on Tretonin, it is simply because Teal'c is that tough, apparently.
Only Mostly Dead: The Ancients, Asgard, Nox and Goa'uld have the ability to resurrect people from death, provided they reach the body soon enough and there is not sufficient damage to make brain reconstruction unfeasible.
Teal'c, and apparently all other Jaffa, are known only by a single name (The word "Teal'c" itself means "strength"). To identify Jaffa within a larger context, they are also identified by their place of origin.
Most Goa'uld and all named Asgard, which makes sense as most impersonate deities from Earth mythology.
The Asgard place testing sites on the planets that they protect in order to determine when the inhabitants are capable of understanding that they are aliens, not gods, and can interact with them on equal footing. These sites judge their selflessness and courage, but also require that they have a knowledge of pi (The ratio of a circle's radius to its circumference) to indicate that their society has developed a knowledge of mathematics and geometry.
In "Touchstone," General Hammond meets with a contact he has in order to track down the missing stargate. They met in a park and the contact suggests they go for a walk to make it harder for parabolic microphones to listen in.
Sam's park-bench meeting with Agent Barrett in "Smoke and Mirrors" after he warns her that his office is bugged.
P-R
Paintball Episode: A couple of them, involving the Goa'uld intar training weapon instead of paintball guns.
Panspermia: The Ancients lived on Earth millions of years before humanity evolved, and when they left for the Pegasus Galaxy they re-seeded life throughout the Mlky Way and caused a "second evolution" of their form. In season nine, it was revealed that they had not originally evolved on Earth themselves, but had traveled there millions of years before that from their home galaxy.
Pet the Dog: Apophis gets a very brief Pet the Dog moment while he is dying in Stargate Command's medical ward, calling for his beloved queen in his final moments. He reverts to evil form when brought Back from the Dead.
Phlebotinum Dependence: Several examples, all the Goa'uld's fault in one way or another.
Planet of Hats: Many, often remaining identical to their culture of origin from when they were abducted off Earth thousands of years ago.
Playing Pictionary: Played with. Daniel and Sam are presented with a thermal image of the symbiote inside of Teal'c, and they play dumb:
Daniel: Oh, that's very good! Did you draw that yourself? Sam: What is it? Daniel: That... That's a duck, isn't it?
Teal'c in the early seasons. The third episode, "Emancipation," famously ended on the line "What is an Oprah?"
Vala, who never did get the opportunity that Tealc did to assimilate and learn about Earth culture, and asked the rest of SG-1 to stop using cultural expressions that she would not understand.
Daniel Jackson, despite being the one actually from Earth, did not understand what Colonel Mitchell meant when he said they were dealing with a John McClane, and Teal'c had to explain that it was a reference to Die Hard.
Portal Cut: Objects are only sent through the gate in one piece; when only part of an object is past the event horizon it is held in a hyperspace buffer until the rest of the object enters the gate and the entire thing is transported to the next gate. If the gate were to shut down with part of an object in the buffer that part is lost forever; Major Kawalsky is killed this way in the first season.
Portal Slam: The Stargate is open as long as the directors say, so it is not unusual for characters to miss the wormhole. Also, when the iris is closed on the receiving end of a wormhole anything that attempts to travel through it suffers a "bugs on a windshield" death. O'Neill coldly orders this done to the character played by Rene Auberjonois, but to be fair he was a white supremacist leader.
Power of Trust: In "Icon," Daniel spends several months recuperating in the home of Jared Kane and his wife Leda. Over the months, Leda became infatuated with Daniel, particularly since Jared had spent progressively less time at home over the past few years as his political responsibilities grew. When Daniel is trying to get Jared to launch a joint military assault in combination with the SGC, he asks Leda to help persuade him, but Jared has noticed their relationship and demands that Leda answer if she loves Daniel. She hesitates for a moment, then explains that she trusts him.
Power Parasite: The Goa'uld are a literal version. Sometimes, as Ba'al/Adria demonstrated, the hosts' abilities are too powerful for the Goa'uld to handle, and the possession does not work as a result. By contrast, when they take Unas as hosts, they do so because the Unas are far tougher than humans, but their bodies are more difficult to control and repair.
Power Walk: SG-1 frequently enters the Stargate (and exits the other side) in this manner. In fact, the times they do not Power Walk usually indicate that something is wrong. Subverted early on, as shortcomings in Earth's dialing program cause them to be tossed somewhat violently out the other side. Then they improve the program, and it never happens again until they override a safety protocol that they really should not have.
Jack: Teal'c, you are one stubborn son of a bitch!
Precursor Killers: Starting with season four's "Window of Opportunity" the SGC learned that the Ancients suffered from a plague towards the end of their civilization. As the seasons progressed the details were gradually revealed, with the ultimate discovery that the Ori inflicted the plague on the Ancients, inspiring many of them to Ascend to a Higher Plane of Existence, killing the majority of the remaining population and forcing the survivors to flee to the Pegasus Galaxy aboard Atlantis.
Precursors: Probably holds a record for the most precursors, with three confirmed Precursor races and the implication of many more.
The Ancients preceded all other life, built the stargates, and had an undefined relationship with Ancient Rome, potentially teaching them how to effectively build roads and speak Latin. They are either benevolent or neglectful, depending on your point of view and perspective on self-determination.
The Goa'uld ruled the Earth for approximately five thousand years and introduced the oldest writing systems and organized living, essentially creating human civilization. However, they brutally oppressed humanity during their reign and have done their best to make sure that we do not build atop the foundation that they left.
The Oannes of "Fire and Water" and the GIANT ALIENS! (For full effect, say it with a Dutch accent) of "Crystal Skull" have some sort of connection with Babylon and the Mayans, respectively, but whether they shaped those societies or simply encountered them was never revealed.
Premature Encapsulation: "Tangent" should have been called "Failsafe", and "Failsafe" should have been called "Point of No Return".
The early seasons used NEC monitors for desktop computers.
Samantha Carter uses a Dell Inspiron laptop in the first eight seasons of the show. Though it could have originally been considered as a Red Stapler effect, her switching to a Dell XPS in season nine sealed the deal.
In one episode in season nine, Col. Mitchell and another Col. Mitchell from another universe are seen sitting at a table drinking Aquafina-brand bottled water.
Proud Warrior Race Guy: Teal'c of Chulak, First Prime of Apophis. The Jaffa have lived as a warrior society for so long that they use the same word ('kek') for both 'weakness' and 'death,' since if one is weak they might as well be dead.
Psychic Powers: "Rite of Passage", "Metamorphosis", "Prophecy", "Prototype". Also, the Priors of the Ori are given telekinetic powers.
Punch! Punch! Punch! Uh Oh...: Done deliberately by Daniel in "The Devil You Know". About to be led away from a chamber after being tortured, he punches one of the Jaffa in the gut which only annoys the Jaffa, who slugs Daniel into the table across the room... which lets Daniel pick up a comlink he had spotted there a moment before.
Putting the Band Back Together: Season nine starts with SG-1 effectively decommissioned as its three remaining members moved on to new positions following the defeat of the Goa'uld: Teal'c had left Earth to help form the new Free Jaffa Nation government, Daniel Jackson was going to Atlantis aboard the Daedalus, and Lieutenant Colonel Samantha Carter had been reassigned to Area 51 for research and development. Lieutenant Colonel Cameron Mitchell, SG-1's new commander, decided to reunite its former members as opposed to building a whole new team.
Race Lift: When the current host of a Goa'uld does not match the race that inhabited their original Earth domain the show often documents the chain of events that lead the symbiote to change its human body. However, Zipacna, a Mayan deity, is portrayed by caucasian Kevin Durand with no explanation.
Rage Against the Heavens: Strictly against the Ori, but they are clearly a thinly-disguised version of a popular real-life religion. Although after defeated, people admit the teachings are not bad, it was the soul-stealing it was used for.
Rage Helm: Many of the helmets worn by high-ranking Jaffa.
Ragnarok Proofing: Ancient technology still works after being abandoned for a million years.
Ramming Always Works: Bra'tac attempts to ram an Ori mothership with a Goa'uld ha'tak once it becomes clear that their traditional weapons will not be able to penetrate the shields. The shields of the Ori ship hold and the mothership disintegrates in a fireball.
Real After All: Rothman originally appears in an episode that is All Just a Dream, and so is revealed at the end to never have "really" been in the show at all, but he appeared in later episodes as an actual character.
Vaitiare Bandera (Sha're) was married to Michael Shanks (Daniel Jackson) in real life, and was pregnant with his child when her character was written as carrying Apophis' son.
Michael Shanks got appendicitis during the filming of "Nemesis", so Daniel Jackson was written out of most of the action in that episode and "Small Victories" by also giving him appendicitis.
Carter temporarily changed her primary weapon from the P90 to the custom-built "Carter Special" starting in the middle of season seven because the show's suppliers ran short of P90 blanks during the invasion of Iraq.
At a convention panel, actor Don S. Davis (General Hammond) was asked what role he would play if given a choice of switching characters, and he responded that he would play his own role since he had the best chair on the set. When Hammond returned in "Prometheus Unbound" after he was promoted away from the SGC, he made a point of taking the chair with him when boarded the Prometheus.
Vala's pregnancy in season nine stemmed from Claudia Black's real-life pregnancy.
Really 700 Years Old: The Goa'uld grant their hosts increased longevity, which can be supplemented by the use of a sarcophagus, so the various System Lords and minor Goa'uld encountered over the course of the series are hundreds, sometimes thousands of years old. Apophis' host was actually a scribe in an Egyptian temple before the overthrow of the Goa'uld on Earth, making him at least five thousand years old.
Real Trailer, Fake Series: In the midst of all the half-scenes of "200" was one completed trailer for a series starring Teal'c as a Private Investigator. It appeared right at the opening of act four, right at the end of the real commcercials, to increase the chance of it being mistake for an actual production.
Recut: Children of the Gods, the two-hour premier of the series, was recut and re-released in 2009 as a DVD-film. It included new footage, composed of new CGI and a deleted scene, a re-score of the soundtrack, and the removal of the full-frontal nudity that was forced to be addedto mark the show as "adult."
Assorted SGC personnel appear in order to make first (violent) contact with the enemy before SG1 comes in to save the day, particularly in the early seasons.
When a pair of scientists decide to tag along and rescue SG-1 in "The Other Guys," Coombs points out that they "might as well be wearing red shirts." Soon after he says this, Khonsu, who is dressed all in red, is killed.
Reed Richards Is Useless: The show leans on Like Reality Unless Noted; while it several times alludes to slowly introducing alien technologies to the general populace, there are few outright signs of this shown on the show. The episode "Bounty" explores this trope a little bit, as Carter and Dr. Lee are attending a technology symposium and Lee complains about how he has to deliberately sabotage his own presentation in order to not appear too advanced. Carter remarks that they need to make it look like there is a natural development process for these technologies, with a lot of trial-and-error and bugs along the way, before the final product is revealed to the public.
In "The Sentinel," Colonel Sean Grieves and Lt. Kershaw are introduced as members of the rogue NID team that was captured by the SGC in "Shades of Grey." However, neither character appeared in the prior episode, and the "Previously On..." opening of "The Sentinel" edited them into the older footage.
Lieutenant Colonel Cameron Mitchell became the lead character in season nine, introduced as the new senior officer of SG-1 after the promotion or reassignment of all its former members. Cameron is described as a former F-302 pilot who fought against Anubis in the battle over Antarctica during "Lost City," and several scenes were shot that took place during that episodes time-frame to show other members of SG-1 interacting with him.
Reset Button: Used very rarely (except in time-travel episodes), and then usually not without some kind of repercussions for using the button itself. In the series finale, though, there was a literal reset button... which still had a somewhat drastic repercussion for one of the characters.
Re Tool: Season eight was intended to be the final season of the show, and saw the conclusion of almost all ongoing storylines: The Goa'uld were overthrown, the Jaffa gained their freedom, the Replicators were destroyed, and there were hints that Jack and Sam were finally going to resolve their sexual tension. When the series was renewed for season nine they introduced two new main characters (Colonel Mitchell and General Landry) removed Jack from the series, and introduced the Ori as the new Big Bad.
Revenge by Proxy: Bra'tac believes that Teal'c believes that Arkad, a cowardly Jaffa that Teal'c had defeated in battle while serving as Apophis' First Prime, killed Teal'c's mother in revenge for his defeat. In "Talion," Arkad himself confirms this, explaining that it was revenge for Teal'c killing his own parents and sister during their conflict. Afterwards, however,Teal'c tells Bra'tac that if Arkad was responsible then he was too much of a coward to do it himself, since Teal'c had tracked down and killed the actual murderer years ago.
When Carter is first introduced to the SGC and explains how excited she is to go through the stargate, Major Kawalsky condescendingly asks her if she has ever pulled out of a simulated bombing run in an F-16 at eight-plus g's. Her only response is a calm "yes," after which Kawalsky has to pause and look around the table before covering himself by mumbling that the experience is even worse.
The Right Of A Superior Species: In "Pretense", the Goa'uld Zipacna justifies the taking of human hosts by claiming superiority to humanity and comparing the practice to the hunting and fishing practiced by humans.
Right Makes Might: In season nine's "The Scourge," Mitchell asks Teal'c if he ever doubted that the Goa'uld would be overthrown since they had vastly superior technology and resources compared to Earth. Teal'c explains that he never doubted that the Goa'uld would eventually be defeated, even if it did not necessarily happen in his own lifetime, since Earth and the Free Jaffa had something much more important: A just cause.
Rock Beats Laser: Earth's conventional firearms and other conventional weapons are usually quite adequate against the supposedly more advanced enemy alien armies they fight.
Rock Bottom: In "Avalon," Part 1, Vala and Daniel are trapped in a stone room with an Ancient philosophy puzzle, and Vala refuses to wait for Daniel to figure it out. When he angrily tells her to stop so he can think, she responds "we're already trapped in here, how much worse can it get?" When the ceiling begins to descend she says that she knew it was a mistake the moment she said it.
O'Neill inviting the rest of SG-1 to go fishing and the various ways they uncomfortably refuse. The offer is made across multiple seasons, and even continues after he has left the show when General Landry invites SG-1 to visit O'Neill's cabin.
O'Neill making frequent references to "memos," usually to explain that he had not seen the latest memo that explained what would be occuring in that episodes.
Mary Steenburgen, a Real Life actress, is frequently mentioned as either O'Neill's favorite actress or his sexual fantasy.
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.
Saw Star Wars 27 Times: Teal'c and O'Neill drop by Carter's place with pizza and Star Wars, 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.
Scary Dogmatic Aliens: 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.
Sci-Fi Name Buzzwords: When Vala pitches a story idea based onThe Wizard of Oz, 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.
Sci-Fi Writers Have No Sense of Scale: 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.
Screw The Rules, I Have Connections!: 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.
In the pilot episode, O'Neil(l) admits, in his roundabout way, that his report on the 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 Obstructive and Corrupt BureaucratSenator Robert Kinsey shuts down Stargate Command.
In the Ori arc, three ascended ancients are shown to do this to help humanity.
Seinfeldian Conversation: 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.
Self Insert Fic: "Wormhole X-Treme!" reveals that when Martin originally wrote his treatment for the Show Within a Show, 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.
Self-Parody: The self-referential episodes "Wormhole X-Treme!" and "200" revolve around the making of a Show Within a Show based on the exploits of SG-1, with many jokes and insults aimed at sci-fi cliches and past stories of the SGC.
Semper Fi: SG-3 is a dedicated combat support group composed of US Marines. It was originally commanded by Colonel Makepeace, former Trope Namer of Hero of Another Story, and then lead by Colonel Reynolds in the later seasons.
Send in the Clones: Ba'al's clones (to great comedic effect) and, to a much lesser extent, the Asgard.
Shaggy Frog Story: Combined with Brick Joke 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.
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 "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.
Ship Tease: 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.
Shot to the Heart: 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.
Show Within a Show: 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.
There are a whole lot of 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, upload a virus to 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."
The American submarine briefly mentioned in the episode "Small Victories" as being ready to destroy the Russian sub is named USS Dallas.
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. 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 "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.
O'Neill wants to call the Prometheus the Enterprise.
A season seven episode was actually titled "Enemy Mine''.
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 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 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 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 Honorverse, treecats 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 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.
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.
"'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.
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.
Sincerity Mode: 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.
Single-Biome Planet: 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.
Sliding Scale of Idealism vs. Cynicism: 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.
Soft Spoken Sadist: The Goa'uld Tanith, who politely wiped out the Tollans.
Something Only They Would Say: 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."
So Proud of You: In "Talion," Bra'tac explains that Teal'c is like a son to him and that he is very proud of what he has accomplished.
Sound Effect Bleep: In "Heroes," O'Neill goes on a tirade against Senator Kinsey, most of which is drowned out by the alarm announcing an incoming wormhole.
Space Fighter: Notable in that the 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 more impressive than practical.
Space Is an Ocean: 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.
Space Mines: "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.
Special Guest: 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.
Spit Take: In "Ripple Effect" Colonel Mitchell gets into a rather animated conversation (With himself) about "the spit take of all spit takes."
Stalking Is Love: 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.
The Starscream: 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.
Stating the Simple Solution: When O'Neill was serving as a 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 why he does not just shoot the guard, they decide to go with that.
Sterility Plague: In the Bad Future 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.
Stock Footage: The gate dialing and opening — sometimes subverted with powerful effect when things go wrong.
Stock Footage Failure: A tiny one: In one episode, when an Ori ship is in orbit around a planet, the planet surface is Earth's, despite it being an alien planet. Take a look◊.
Strange Minds Think Alike: 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 Sun Tzu, but he then amended that Landry might have actually been repeating Dr. Phil 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.
Stupid Evil: 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 gloating or pointless sadism.
Stupid Sacrifice: Averted by the ever Genre Savvy 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?
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 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.
Sugar and Ice Personality: At first Teal'c is cold toward everyone except O'Neill, which is understandable considering he migrated from another planet, but over the years more and more of his soft side begins to show.
Suspiciously Specific Denial: When the pilot was Re Cut 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.
Sword Fight: Mitchell fights two of Merlin's holographic knights in season nine: The first is more of a test than an actual enemy, and he manages to defeat it after gaining a new determination, but the second is a security device that is about to kill him when Daniel comes to his rescue.
Sympathetic Criminal: In "Bad Guys", SG-1 ends up playing this role, mostly by accident.
Sympathetic Murder Backstory: 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.
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 Starship Troopers for movie night since they spent the episode 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 "is it ever."
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." Subverted in that the weapons of the Ancient outpost get there first, and Hammond is only too happy to break off.
Tantrum Throwing: Cam gets frustrated and trashes his room in "Unending".
Technobabble: Mostly courtesy of Carter, McKay, and a couple of others. O'Neill serves as a bit of a Greek Chorus 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.
Teleporters and Transporters: The Stargates and ring transport platforms inherited from the movie are the most common. The Asgard bring the Star Trek-style "beams" into play.
Teleport Interdiction: The iris is used to prevent anything unwanted from coming through the stargate.
That Man Is Dead: 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.
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.
They Called Me Mad!: 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 Ancient Astronauts in the setting. In the case of Daniel and his grandfather, though, it is a bit of a Contrived Coincidence to have two scientists called mad in the same family researching completely different alien artifacts.
Throat Light: When a person is being tortured with the Goa'uld 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
Time-Compression Montage: "Unending", the series finale, had one of these, set to Creedence Clearwater Revival's "Have You Ever Seen the Rain?"
Tomato in the Mirror: 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.
Tomboyish Name: Samantha "Sam" Carter. In the pilot O'Neill 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.
Tranquillizer Dart: Osiris is twice shot by a tranquilizer dart tipped with a Goa'uld specific sedative.
Translation Convention: 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.
Translator Microbes: Though never mentioned in the show, 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 aliens speak English.
Transplanted Humans: 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.
Trial by Combat: The Jaffa believe firmly in the concept of Asskicking Equals Authority; 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.
Tricolours With Rusting Rockets: The Russians manage to acquire a Stargate and briefly run their own program. Later, Russian officers are part of the international program.
Samantha Carter: We were a team. No one else can even begin to understand what that means.
Two Keyed Lock: Sometimes it is passwords, sometimes it is keys.
Two of Your Earth Minutes: 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 he always wanted to say that.
Typhoid Mary: 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.
Unflinching Walk: Teal'c pulls this off in the episode "Talion".
Teal'c: I am leaving, you are about to explode.
Ungrateful Bastard: 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.
The Unsmile: 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.
Unwanted Rescue: 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.
Unresolved Sexual Tension: Carter and O'Neill. Word Of God states that just about the nanosecond Jack retired, he and Sam got it together and got it on. A deleted scene from the Stargate Atlantis 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 Lie Detector gets a false positive because they 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.
Unobtanium: 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". 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.
Unusual Euphemism: "I told her that she should attempt procreation... with herself."
Unusually Uninteresting Sight: 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.
Villain Ball: 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.
Villain Pedigree: The Ori and Replicator pull this on the Goa'uld.
Wasn't That Fun?: 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.
The Watson: 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.
We Have Forgotten the Phlebotinum: Several cases of needing something from another base, planet, or needing a bit of MacGyvering to make a new doohickey.
Welcome to the Liberator: Jonas' arrival and departure from the team coincide perfectly with Daniel's departure and return.
We Will Use Manual Labor in the Future: Justified for the the Goa'uld, who keep most of their human slaves in Medieval Stasis to prevent rebellion. Generally averted by most of the other technologically advanced civilizations.
Wham Episode: In the episode "Heroes", the death of Dr. Janet Fraiser. To add extra oomph, Killed Off for Real is played with in this episode, as two characters (including an Red Shirt) receive potentially fatal wounds before it is revealed quite shockingly that Janet, whom the viewer does not even know got injured, is the one who actually died.
What Could Have Been: 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.
What Happened to the Mouse?: So many incidents that the show gets its own folder on the Live Action TV subpage. One of the most notorious examples is the fact that Jonas Quinn, a member of SG-1 for an entire season, is never mentioned once after the events of "Fallout".
What the Hell, Hero?: Tricky moral issues abound, but the most obvious example is the end of "Unnatural Selection". O'Neill, being the hardened military man, is the one most often called on it. He usually justifies it with I Did What I Had to Do, and he may be right.
What We Now Know to Be True: The Tollan have studied quantum physics... "among other misconceptions of elementary science".
Dr. Jackson: And the last one is Lord Yu. Dr. Weir: Yu? Dr. Jackson: Don't. Every joke, every pun, done to death. Seriously.
Who Watches The Watchmen?: 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.
Who Writes This Crap?!: 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.
Why Won't You Die?: Apophis had a habit of returning from supposed (And 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 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.
Will They or Won't They?: In several episodes, the writers play with romantic tension between O'Neill and Carter, and two different Alternate Reality 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.
Col. O'Neill: "I'd like to take this opportunity to say that this is a very poorly designed bomb, and I think we should say something to somebody about it when we get back."
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 (well, more than usual) and recklessly use their powers, starting a Bar Brawl 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.
Within Parameters: 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.
With Lyrics: 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.
Won't Take "Yes" for an Answer: 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.
Word Of God: 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.
The Worf Barrage: In the episode "Beachhead", an Ori force-field is powered by the weapons fired at it.
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)
Worthy Opponent: 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.
Wrong Genre Savvy: 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.
X Treme Kool Letterz: 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.
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 it takes her fifty years.
Ye Olde Butcherede Englishe: 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.
"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.
You Are Not Ready: 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, 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.
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.'
You Can't Go Home Again: 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.
You Didn't Ask: 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."
You Had Us Worried There: O'Neill jumping an about-to-explode Stargate through the Earth, with a scare about whether or not he was able to eject.
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 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 Bounty Hunter Odai Ventrell in "Bounty". He then reappears as Lucian Alliance member Varro in Stargate Universe.
Younger than They Look: 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.
Your Costume Needs Work: When O'Neill is on the set of "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.
Your Mom: 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.
"These and other clichés will be available to you all for one more day of training with me. After that, you'll either be assigned to an SG team... or not."
