Line #3 YMMV/HappyDays


1	* AlternativeCharacterInterpretation: Was Fonzie's aversion to liver in "The Muckrakers" an AbsurdPhobia, or an exaggerated case of DoesNotLikeSpam?
2	* SugarWiki/AwesomeMusic:
3	** The theme song is very groovy and upbeat with its incorporations of trumpet, keyboard, and hand claps, all while containing a sing-along chorus with upbeat vocals. It culminates in a feel-good tune reminiscent of TheFifties.
4	** Also, Music/BillHaleyAndHisComets' "[[RealSongThemeTune Rock Around the Clock]]", which was used as the theme for the first two seasons. Most of the actual '50s and '60s music heard within the show itself also counts.
5	** The "Pumps Your Blood" song.
6	* BaseBreakingCharacter: Chachi-nated, or De-Chachi-nated? He was liked by fangirls for being a MrFanservice and his relationship with Joanie, while other viewers found him an unnecessary addition to the cast with an annoying CatchPhrase. Nick at Nite even made a marathon out of the "Chachi/No Chachi" premise, and viewers got to vote.
7	* BrokenBase: Despite being the TropeNamer for JumpingTheShark, a term that was coined when Fonzie jumped over a shark during Season 5, opinions widely vary among fans on when the show actually started going downhill. Some argue that the show went downhill as early as Season 3, when the show started being taped in front of a live audience. Some will say when Fonzie actually jumped the shark. Others will say when Richie and Ralph left the show after Season 7. A number of fans will even argue that the show stayed good for all 11 seasons.
8	* CommonKnowledge: People think Fonzie's SignatureMove is saying his iconic {{Catchphrase}} “Ayyyyy!” while [[HasTwoThumbsAnd lifting his two thumbs]], while he indeed did both gestures regularly, he has only ever done both at once only ''one time''.
9	* EnsembleDarkHorse:
10	** Fonzie in the first two seasons, so much that he became a BreakoutCharacter and was promoted to second billing, after Creator/RonHoward.[[note]]Creator/HenryWinkler refused to be billed above Howard.[[/note]]
11	** Mork was only supposed to be a one-shot character and his episode AllJustADream, but Creator/RobinWilliams' performance was such a hit that the episode was revised to make the events real after all and gave him his own [[Series/MorkAndMindy spinoff]].
12	** Fonzie's TomboyWithAGirlyStreak love interest Pinky only appears in one three-part episode but is among the show's most popular recurring characters.
13	** Surprisingly down-to-Earth TeenIdol Cindy Shea (Creator/CherylLadd) from "Wish Upon a Star" and the unnamed DeadpanSnarker burglar from "The Cunningham Caper" are both one-time characters but are still decently iconic ones.
14	* EvenBetterSequel: Many fans regard season 2 as the best season of the show, improving on the already decent but not quite fully formed aspects of season 1 while avoiding the base-breaking changes of season 3 onward.
15	* FranchiseOriginalSin: The moment of [[JumpingTheShark vertical ascension over an aquatic carnivorous animal]] is considered merely the point where Fonzie's {{Flanderization}} into a superhuman and the loss of the 1950s motif reached its zenith. Both those things had subtly been going on as the seasonal rot kicked in.
16	* HarsherInHindsight:
17	** Joanie and Chachi's romance was irrevocably ruined after Scott Baio's insensitive statement that Erin Moran deserved her early death because of her drug addictions (she actually died of cancer). Baio later admitted his statement was made in a moment of misinformation and grief, and he didn't truly mean it that way, to some, the damage was still done.
18	** In the episode [[https://youtu.be/LeL5m1GPurM “A Little Case of Revenge”]], Tom Hanks plays Dr. Dwayne Twitchell, a guy who wanted to beat up Fonzie because when he was a kid, the Fonz pushed him off a swing set, so he took revenge on the Fonz by learning martial arts. Seven years after the episode aired, Creator/HenryWinkler would end up getting fired after two weeks of principal photography on the Tom Hanks film ''Film/TurnerAndHooch'' due to HostilityOnTheSet and CreativeDifferences. As Winkler stated in a 2012 interview on ''The Howard Stern Show'':
19	-->"Let's just say I got along better with Hooch than I did with [[Creator/TomHanks Turner]]."
20	* HilariousInHindsight:
21	** In one episode, a martial arts class is taught by Arnold, played by Creator/PatMorita. Happily, [[Film/TheKarateKid1984 Daniel-San]] was a better student than [[ButtMonkey Richie]].
22	** Fonzie would not be the only television character to [[WesternAnimation/RockosModernLife own a dog named "Spunky"]].
23	** During the show's early run, Joanie was part of a Girl Scout troupe called the "[[ScoutOut Junior Chipmunks]]". The same name was used 26 years later for the scout troupe Kronk leads during his service at Camp Chippamunka in ''WesternAnimation/TheEmperorsNewGroove''.
24	* HoYay: In "Just a Piccalo", when Joanie agrees to go to Pfister Park with Jenny Piccalo to steal the statue there, Jenny kisses Joanie's hands to express her thankfulness.
25	* MorePopularReplacement:
26	** Before Chachi, in early seasons Fonzie had another younger cousin named Spike who completely disappeared after Season 4. Chachi is introduced in Season 5 in a similar role, but is eventually PromotedToLoveInterest and ends up becoming a main character until the end of the show. It helps that Chachi was very popular with teenage girls and was also a different character from his cousin, while Spike just acted like a mini-Fonzie, even wearing the same clothes.
27	** Arnold was the owner of the Drive-In in Season 3, is replaced by Al in seasons 4-9, and eventually comes back after Al's departure in Season 10. Both characters were well-liked and it's hard to tell which of them is more popular.
28	* ReplacementScrappy: Roger, the nephew introduced after the departure of the main hero Richie Cunningham. Unlike adorkable everyman Richie, Roger is seen by most fans as a forgettable FlatCharacter.
29	* RetroactiveRecognition: The burglar in season two's "The Cunningham Caper" is played by Herb Edelman, who is much better known nowadays for being Dorothy Zbornak's ex-husband Stanley on ''Series/TheGoldenGirls''.
30	%%* TheScrappy: Roger, and really anyone introduced in Season 8 and beyond.
31	* SeasonalRot: It started out as a very cool, low-key show, then became the ideal version of a standard sitcom with a StudioAudience. It started getting worse (the Trope-Named Shark-Jump) even before Richie left, but only got worse after that. Fonzie got a temporary full-time girlfriend for one season, and things got increasingly worse with gimmicks (one of them, having an alien appear, is forgivable considering it gave Creator/RobinWilliams his big break and he made the most of it with his comedy genius creating a hilarious episode) and nonsense until a thankfully fantastic final episode.
32	* SignatureScene: Even if you have never seen the show or even the specific scene in question, you are almost certainly aware of the fact that Fonzie jumped over a shark on water skis, thanks to the phrase "JumpingTheShark" entering the pop culture lexicon.
33	* {{Squick}}: In "The Cunningham Caper", Joanie talking about barf bags. Also, all the bad meat in the liver episode. Squicked out Fonzie too.
34	* SuspiciouslySimilarSong: The theme from Season 3 onward has a chorus that seems heavily inspired by the intro and closing of "[[https://www.youtube.com/watch?v=kato7EMyhWY Can't We Be Sweethearts]]" by the Cleftones, as was at least one piece of incidental background music heard in the show's first two seasons.
35	* TheyWastedAPerfectlyGoodCharacter: Chuck Cunningham had so much potential as an older brother to Richie and Joanie, but the writers simply got rid of him only because they thought Fonzie was already a "big brother figure" to Richie. At the very least, they could have made Chuck either a recurring guest character, or acknowledge his existence when they wrote him off the show.
36	* ValuesResonance: The episode "The Best Man" tackles the issue of racial segregation in 1974, when civil unrest was rampant.
