* AcceptableTargets:
** In this 'verse, Canada is an entire nation of {{Butt Monkey}}s. At least in one episode.
** Laurie was considered fair game because of what a complete bitch she was, and that made it okay to make fun of how she sleeps around.
*** Likewise, Kelso's status as the ButtMonkey of the cast was due in part to sleeping around behind Jackie's back. Not only did none of the characters feel any sympathy for the misery that resulted from this, they would occasionally make it ''worse.''
* AwesomeMusic / EarWorm: ''[[https://www.youtube.com/watch?v=x-6_VSdC9_w That 70's Song]]'', naturally.
* BaseBreakingCharacter:
** Donna. Some people like her and thinks she adds a lot of funny moments to the show, others think she's a {{Jerkass}} and a {{hypocrite}} who [[StrawFeminist uses feminism to get her way in an argument or some other aspect of her life]] when she has shown she's not above acting like a stereotypical woman if it benefits her somehow. The fact that she often overacts to some of the smaller things Eric has done and treats him like crap even when he really ''hasn't'' done anything wrong and never gets called out on it doesn't help.
** Some Donna defenders would point out that Eric can at times come across as casually chauvinistic and untrusting of Donna, often playing up the jealous, possessive boyfriend type that he was supposed to subvert, and is often equally at fault for the problems that arise in their relationship. Indeed, even among those that shipped the couple conversations would often lead to who was the bigger {{Jerkass}} in the relationship.
* CounterpartComparison: Let's see- we've got TheEveryman who is essentially the leader, a [[TooDumbToLive dumb]] [[ThePrankster jokester]], a [[TheStoner scruffy kid]] [[AbusiveParents with a crappy home life]], [[FunnyForeigner a newbie who learns about our culture]], a [[UptownGirl beautiful girl in love with the scruffy guy]] who will [[GirlyBruiser kick ass if needed]], and a {{Tomboy}} in a complicated relationship with the leader. Are we talking about the gang from this show, or the Literature/{{Animorphs}}? They're very similar, except Jackie's counterpart Rachel went BloodKnight later on, Tobias didn't have any weed to help him (he instead got [[ShapeshifterModeLock stuck as a hawk]]), Cassie is a [[FriendToAllLivingThings animal lover]] (as opposed to Donna's general tomboyishness) and Ax is almost the polar opposite of Fez (he's a ComicallySerious alien warrior). (Kind of ironic, considering the ''Animorphs'' [[Series/{{Animorphs}} TV series]] also started in 1998.)
* CreatorsPet:
** Randy. Apparently the writers assumed if all of the characters thought that he was perfect, so would the audience.
--->"Randy is perfect. That lady at the fair who did the caricatures? She refused to draw him cause she couldn't find a flaw."
** For many people, Donna and her overall treatment of Eric in their relationship wasn't fair and she was in fact rude to Eric even when they were dating.
* CrossesTheLineTwice: "Grandma's Dead", where Eric's grandmother dies as he is driving her home. Seeing Grandma Foreman's lifeless body flop around in Eric's passenger seat, or having Kelso crawl over her to reach his 8-Track, would not be nearly as funny if the viewers had not wanted to [[{{Jerkass}} kill the character themselves.]]
* DesignatedVillain:
** Kelso occasionally. He was a jerk, but sometimes he was portrayed as the bad guy when he was really being reasonable. When he lent Jackie his van and she smashed it, he reasonably wants her to pay to have it fixed, but Jackie refuses because she bought him gifts while they were together.
** Eric himself, especially in regards to his relationship with Donna. The show tries to display him as an idiotic pervert at times who believes too much in old fashioned ways[[note]]Mostly thanks to Red[[/note]], but more often than not he makes [[StrawmanHasAPoint far more convincing arguments than the writers intended]], especially when some of the points Donna tries to make border-line on flatout [[DomesticAbuse domestic/emotional abuse.]]
* EnsembleDarkHorse:
** Leo was very popular with the fans, to the point where he became a main character in the Season 4. [[RealLifeWritesThePlot Then Tommy Chong was sent to prison midway through the season]]. His PromotionToOpeningTitles in Season 8 coincided with his return to the show.
** Sad sack Roy Keene (played by Jim Gaffigan) only appeared occasionally but ended up very popular.
* FanficFuel: The finale cut off at the very last second of 1979, and never featured a WhereAreTheyNowEpilogue or DistantFinale. Many fanfic writers came up with their own, and given how things turned out in Season 8, most of these are {{Fix Fic}}s.
* FanonDiscontinuity: Many fans refuse to acknowledge the existence of the eighth season and prefer the cut-off to be somewhere mid-seventh season.
* FanPreferredCouple Hyde/Jackie, which is also a subversion; the two ''were'' together for a large chunk of the series (about 3 seasons), but officially ended in season seven after some other temporary break ups. They were very popular with the fandom because they were seen as a surprisingly stable relationship in comparison to Eric and Donna's constant arguments, a stability that only compared to Red and Kitty's relationship. There was a reason why Kelso wanted them to be his daughter's godparents.
* FunnyAneurysmMoment:
** The episode parodying ''Series/CharliesAngels'', including the boys' giving their reason for watching: "the hot blonde with the big rack", happened to air in syndication the day Farrah Fawcett died.
** The next to last episode of season 2, "Cat Fight Club", features Red fantasizing about the year 1997 and bemoaning Laurie dating Kelso with the declaration that he'll "have a heart attack before [he] gets his jetpack." At the time, a crack about how we [[IWantMyJetpack still don't have jetpacks in 2000]] was funny, but it became this as of the season 5 finale, "Celebration Day", when Red really does have a (non-fatal) heart attack as a result of [[spoiler:hearing Laurie and Fez got married so the latter will stay in the country.]] Additionally, in another episode, Red faked a heart attack to get Kitty off his ass about his health.
** The episode "Grandma's Dead" does have a heartbreaking real world example though during the otherwise hilarious funeral scene when each character observes Grandma Forman's open casket and we hear the thoughs that run through their head. Laurie reflects on how life is complicated because you "get all old and die... thank God I'm young and hot!" In light of the death of actress Lisa Robin Kelly at the age of 43, it's cringe-inducing.
* HarsherInHindsight: A big deal is made of Bob and Midge renewing their vows, which is particularly sweet after they'd fought and argued for so long. And then Midge abruptly leaves him and Donna just two seasons later.
* HilariousInHindsight:
** Prior to being neighbors on this show, Red and Bob's actors (Kurtwood Smith and Don Stark) were already neighbors in a sense - Kurtwood played General Galapagos on ''[[WesternAnimation/EekTheCat The Terrible Thunderlizards]]'', and Don played The Rhino in ''WesternAnimation/SpiderManTheAnimatedSeries' '- both of which aired on Saturday mornings on Creator/FoxKids.
** Eric wearing an all-black outfit wishing he could shoot webs and later saying he learned how to fight from Spider-Man. Topher Grace went on to play Venom in ''Film/SpiderMan3'', who had all of Spidey's powers, wore a symbiote that was black as a costume, and could shoot webs.
** In "Going To California," Hyde tells Eric that he "has no problem fooling whitey." Eric reminds Hyde that he's white, and Hyde responds by saying, "Barely." Cut to Season 7, where it is revealed that Hyde is half-black.
** Also in Season 5, after [[spoiler: Jackie and Hyde break up because he cheats on her]], a distraught Hyde turns on the radio to a country music station and says he finally gets country music. [[Series/TheRanch Cue 2016]].
** The fact that Creator/AshtonKutcher and Creator/MilaKunis started dating in 2012 after playing a couple when the show started. It became HeartwarmingInHindsight in February 2014, when they announced their engagement, and as of 2017, are the proud parents of two children.
*** In one episode, Kelso starts donating sperm. Jackie makes him go and get them back because she "wants to have his babies someday."
** In the episode "Tornado Prom", Jackie has an OffToSeeTheWizard dream sequence in which she is Dorothy. Her actress, Mila Kunis, would later play Theodora, the Wicked Witch of the West, in ''Film/OzTheGreatAndPowerful''.
** In "Hyde's Father," Bud tells the kids "That's what his mom says" when asked if he's really Hyde's father. Fast forward a few seasons and turns out he wasn't so far from the truth.
** [[Series/{{Scrubs}} A Kelso]] invoking HasTwoThumbsAnd.
** All of Jackie's lines are funnier when you picture her as [[WesternAnimation/FamilyGuy Meg Griffin]] (who, like Jackie, is a ButtMonkey, though Meg's abuse does cross the line to DudeNotFunny territory, while Jackie's humiliations are more light-hearted).
** Donna once said "I could get arrested. I could go to a girl prison". Cut to [[Series/OrangeIsTheNewBlack 2013]]...
** After he and Red modify a Pong game, Kelso proclaims that home computers are the wave of the future. Creator/AshtonKutcher would later play Creator/SteveJobs in the {{biopic}} ''Film/{{Jobs}}'', as well as computer tech guru Walden Schmidt on ''Series/TwoAndAHalfMen''.
** Eric's love of ''Franchise/StarWars'' when one considers that Topher Grace [[http://www.slashfilm.com/topher-grace-edited-star-wars-prequels-85minute-movie/ edited the Prequel Trilogy into a single 85 minute film]] and removed several of the most hated elements of those films.
** In Season 7's "Let's Spend the Night Together," Eric gets attacked (by a group of women) at a feminist rally. Donna tells him to run... like Bruce (now known as Caitlyn) Jenner. She then curses herself because Eric is too "feminine" to know about sports.
** Both Ashton Kutcher and Wilmer Valderrama would eventually be romantically linked to celebrities [[Creator/DemiMoore named]] [[Creator/DemiLovato Demi]].
** In Season 4's "An Eric Foreman Christmas", Eric winds up coming up with the term "space unicorn" over a decade before Music/ParryGripp [[https://www.youtube.com/watch?v=17o1OlroNSE did.]]
* HoYay: There was an episode where a Eric became friends with a guy called Buddy (played by Creator/JosephGordonLevitt). There was a montage of them hanging out to a Best Friends song, only for it to turn out that Eric's friend was gay. At the end of the episode, Red and Bob had a Best Friends montage.
** Kelso and Fez's relationship constantly toes the line between HeterosexualLifePartners and AmbiguouslyGay. Hyde even lampshades it in one episode in a conversation with Fez:
--> '''Hyde:''' You're like half in love with him aren't you?
** There's also this little gem:
--> '''Kelso:''' ...Did you just kiss my ear a little?
--> '''Fez:''' ...Yes.
--> '''Kelso:''' ''({{beat}})'' I kinda liked it.
** Then there was the episode where Fez had an erotic dream about Kelso.
** They've also kissed:
---> '''Fez:''' Ah, this is tomorrow's school paper. Oh my god, on the front page, there's a picture of me kissing Kelso by the lake!
---> '''Eric:''' Fez, why are you kissing Kelso by the lake?
---> '''Fez:''' We caught a fish, I was excited. I kissed the fish too, but, of course, they don't show you that.
** Discussed in-universe with [[Series/GilligansIsland Gilligan and The Skipper]].
** There's also this little gem from Eric about his relationship with Hyde.
--> (Being friends with Donna) isn't the same as with Hyde. I haven't, you know, touched his fun parts. At least not intentionally.
* MagnificentBastard:
** Hyde, although Red similarly has qualities of it.
** Played straight in the following dialogue:
--> '''Fez:''' Jackie, are any of your college-bound friends "vir-gins"?
--> '''Jackie:''' Fez, it's pronounced "virgins".
--> '''Fez:''' What? No, but, Hyde said--
--> ''[Fez realizes his folly and looks at Hyde]''
--> '''Fez:''' Oh, you MagnificentBastard.
--> '''Hyde:''' I'm sorry, buddy. Oh, and it's pronounced "bas-tard".
* MemeticBadass: Red.
* ParanoiaFuel : Fez could be hiding in your closet ''right now''!
* RetroactiveRecognition:
** Jackie is [[TheOtherDarrin the second voice]] of [[WesternAnimation/FamilyGuy Meg Griffin]].
** [[Series/TheOffice Stanley Hudson]] appears in a brief role as a janitor at the Ted Nugent concert the gang attends in Season 3.
** [[Series/HowIMetYourMother Lily Aldrin]] is a cop who really loves violence.
** [[Series/{{Community}} Dean Pelton]] was putting on women's wear even before he ran Greendale.
* RomanticPlotTumor: Even though most people prefer it to [[TheScrappy Randy]], Eric and Donna's relationship over the series gets to this level at several points, to the point it seems like the writers were [[RelationshipRevolvingDoor trying to think of any reason to break them up so they could get them back together again.]] The crowning example is when [[spoiler:they broke up because Donna wouldn't accept Eric's promise ring, not wanting to be "trapped" in Point Place, listing several reasons because of it. Maybe this would have been understandable... had Donna not almost immediately hooked up with Kelso's brother, who's the ''living embodiment'' of everything she supposedly left Eric because.]] Let's just say it's some of those things that caused Donna to be one of the more [[BaseBreakingCharacter divisive characters]] in the cast...
** This at least gets [[LampshadeHanging acknowledged]] semi-frequently in universe though, with several characters (Hyde being the most frequent) stating they keep getting rather sick of hearing Eric and Donna constantly talking about and discussing every little thing about their relationship.
-->'''Hyde:''' I couldn't put up with one more week of that "Will they won't they" crap.
* SeasonalRot: Opinions vary on exactly how early it started, but ''many'' agree that the season where Kelso and Eric left and brought in [[ReplacementScrappy Randy to replace them]] was the single worst season of the show.
* ShippingGoggles: Fans seem to disregard Hyde's actions in the final season and claim he and Jackie broke up because he didn't want to get married when really the reason was [[AccidentalMarriage the opposite.]]
* StrangledByTheRedString:
** Donna and Randy. Donna is noticeably attracted to Randy while she's still in a relationship with Eric. The fact that the writers also broke up the OfficialCouple (and having it be an off-screen Eric's fault, no less) just to get them together doesn't help.
** Jackie and Fez's RelationshipUpgrade comes pretty close as well, especially since a lot of people weren't happy that she didn't get back together with Hyde. She basically went from regarding Fez as a good friend to being head over heels in love with him in the span of a few episodes. Though it needs to be noted that in an episode from one of the earlier seasons that Jackie has admitted that she found Fez to be attractive.
* StrawmanHasAPoint: After getting Brooke pregnant, Kelso is initially reluctant to get involved or take responsibility, which leads to the others criticizing him. While they're certainly not wrong, Kelso has a pretty understandable response: "Y'know, it's real easy to talk about the right thing when it's not your life."
* TheyWastedAPerfectlyGoodPlot: A lot of the characters' HiddenDepths were ignored in favor of {{Flanderization}} no matter how annoying the directionless StatusQuoIsGod got. Jackie and Kelso got the worst of it - in one episode Jackie was shown to be a great mechanic, and in another episode, Kelso could reprogram a ''VideoGame/{{Pong}}'' table, and nothing was done with either of them.
* WhatAnIdiot:
** Kelso, being TheDitz, is naturally a fountain of this.
*** One of the group's favorite stories is of the time Kelso tried to do the "burning bag of dog poop" prank on someone, but lit the bag prematurely and then stomped it out himself. A frustrated Kelso counters "THE BAG WAS ON FIRE!"
** Eric more or less [[InvokedTrope invokes]] the IdiotBall in "The Good Son," when he tries to lash out by doing something stupid and allows ''Kelso of all people'' to persuade him to bounce a bowling ball off the couch. However, the idea turns out to be even dumber than he thought, as the ball ends up bouncing into the TV. Not many viewers are sympathizing with Eric's OhCrap face at this point.
** A particularly stupid came from Eric kissing another girl (Laurie's college roommate) while he and Donna were starting to form a relationship. Red came down on him for this gloriously.
-->'''Eric:''' It's like bad things are always happening to me. Like I have bad luck or something.\\
'''Red:''' ''(understanding voice)'' Son, you don't have bad luck. The reason bad things happen to you is because you're a dumbass. ''(harshly)'' Now fix it.
* UnintentionallyUnsympathetic: Eric and Donna pressuring Jackie and Hyde to admit their relationship to Kelso- and shaming them for doing it in the first place and keeping it a secret- comes off as rather meddlesome and hypocritical to many fans, considering the two of them didn't seem to have any trouble keeping Kelso's ''actual affair with Laurie'' a secret from Jackie for months. For Kelso himself, the idea that Jackie really owes him anything (after years of dealing with his cheating, passive aggressively insulting her, pestering her for sex, and ditching her with no explanation) has become a point of contention among fans, especially in recent years.
* ValuesDissonance: Ironically falls into this, in spite often [[DeliberateValuesDissonance deliberately invoking it]] for comedy. [[SlutShaming Sleeping around is depicted as one of the worst things people, particularly women, can possibly do.]]
* WhatCouldHaveBeen: Chuck Norris was originally going to play Red, but he was filming Walker, Texas Ranger so Kurtwood Smith was cast.
