* 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, others think she's a bitch and a hypocrite who treats Eric like crap and never gets called out on it.
* 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.
* 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."
* 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.
** An InUniverse example, as Eric is with [[ScrewPolitenessImASenior his grandmother]].
-->'''Eric''': You know, it wouldn't kill you to be nice once in a while. (cue her dropping dead)
* 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/{{Spider-Man}} 3, 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.
** 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.
** [[{{Scrubs}} A Kelso]] invoking HasTwoThumbsAnd.
** All of Jackie's lines are funnier when you picture her as [[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''.
* 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.
* JumpedTheShark: Most fans seem to feel that the show went downhill either when Jackie and Hyde broke up, when Topher Grace (Eric) left the show and was replaced by Josh Meyers (Randy)[[note]]Josh Meyers was only put on the final season of the show because his contract was up with ''Series/{{MADtv}}''[[/note]], when Ashton Kutcher appeared less and less on the show, or [[ArsonMurderAndJaywalking when Donna dyed her hair blond]].
** In universe, one of Fez's dream sequences has a parody of the TropeNamer scene from ''Series/HappyDays''. Hyde notes that it was the worst moment in television and Fez admits he stopped watching after that point.
* 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.
* RetroactiveRecognition: Jackie is [[TheOtherDarrin the second voice]] of [[FamilyGuy Meg Griffin]].
* SeasonalRot: Most fans ''hated'' season 8.
* ShipSinking: Jackie/Kelso after season 5.
* ShipTease: Jackie/Hyde had there fair share of teasing in the early seasons whenever she broke up with Kelso. Both couples actually came to fruition over the course of the series.
* 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."
* TearJerker:
** The season five episode "Nobody's Fault But Mine (Hyde Loves Jackie)." In the last episode, he saw Kelso and Jackie together and thought she was cheating; as payback, he cheats with a nurse he just met. After Kelso explains to Hyde that nothing happened, Hyde and Jackie have a talk. Unfortunately...
-->'''Hyde:''' Come on, Jackie...
-->'''Jackie:''' No, you know what, Steven? I'm sorry... it's over.
** And also from the same episode, particularly this dialogue:
-->'''Hyde:''' Jackie, I love you.
-->'''Jackie:''' Yeah, well I don't love you.
** In the final episode, the Eric/Donna montage (set to Music/BigStar's "Thirteen") followed by his appearing to wish her Happy New Year and apologize for having left her.
* UnfortunateImplications: The fact that Laurie, who is one of the nastiest characters on the show, is also the most sexually active, has some ''very'' unfortunate implications.
** The only time Laurie's promiscuous behavior is not portrayed negatively, or at least as negative as one would think, is [[DoubleStandardRapeFemaleOnMale when Laurie sexually assaults Kelso]]. Not [[AllMenArePerverts only did]] [[AManIsAlwaysEager Kelso]] [[NotIfTheyEnjoyedItRationalization enjoy it]], but the whole thing is portrayed as him cheating on Jackie as if it was his fault that he was ''forced'' to have sex with someone else. Just because he thought she was hot and/or enjoyed the experience.
* 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.
