* 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.
* BaseBreaker: 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 thing's 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.
* CanonSue: Randy to the nth degree. He had all of the best attributes of Kelso (ChickMagnet) and Eric (DeadpanSnarker) with none of their flaws, ''[[CreatorsPet Red adored him]]'', he hooked up with Donna, but she dumps him, and became [[TheHead the group's leader]] out of nowhere. He was like a really bad self-insert character.
* CluelessAesop: Sometimes it does [[SomeAnvilsNeedToBeDropped drop a few anvils that need to be said]], but most of the time, most of aesops come off as "[[FamilyUnfriendlyAesop women are just inherently better than men and men aren't allow to criticize their actions no matter how heinous they are.]]" As many actual feminist will tell you, not only is this the complete opposite of what actual feminism is, [[note]]that being both genders are to be treated as ''equals'', with nether one being portrayed as inherently better than the other[[/note]] but is both equally offensive to men ''and'' women. [[note]]Because it portrays women as needing special treatment for just being women.[[/note]]
* 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."
* 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.
* EnsembleDarkHorse:
** Leo was very popular with the fans, to the point where he became a main character in the eighth season.
*** He actually became a main character back in Season 4, but 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.
** Red, due to his no-nonsense attitude along with having some of the best lines in the show.
* 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.
* 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.
* HilariousInHindsight:
** 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.
** 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 2015, they now have a baby together.
** 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.
* 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]].
* 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]].
* 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 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: them breaking 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 pretty much the ''living embodiment'' of everything she supposedly left Eric because.]] Let's just say it's some of those things that [[BaseBreaker caused Donna to be one of the more "diverse" characters in the cast...]]
** This at least gets [[LampshadeHanging acknowledge]] semi-frequently in universe though, with several characters, with Hyde being the most frequent offender, stating they keep getting rather sick of hearing Eric and Donna constantly talking about and discussing every little thing about their relationship in universe.
* SeasonalRot: The opinion is out on exactly how early it started, but ''many'' agree that the season where Kelso and Eric left and it brought in [[ReplacementScrappy Randy to replace them]] was the single worst season of the show.
* 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.
* 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."
* 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.
