A proper white man adopts two street-wise black boys. HilarityEnsues.

''Diff'rent Strokes'' (1978-86) made a star of Gary Coleman as Arnold Jackson, the younger of the two boys. Todd Bridges was his older brother Willis and Conrad Bain was the proper white man, Mr. Drummond. As one of [=NBC=]'s few late-'70s hits, it quickly launched a spinoff in ''Series/TheFactsOfLife'' the following year. [[Main/RonaldReagan First Lady Nancy Reagan]] made a guest appearance in a VerySpecialEpisode about drug abuse, and [=ABC=]'s ''Series/{{Webster}}'' was a FollowTheLeader rival. Ironically, ''Diff'rent Strokes'' itself actually moved to ABC when it got canceled by NBC. The theme was co-written and performed by Alan Thicke.

Unfortunately, this show is best remembered now both for its [[Main/VerySpecialEpisode special episodes]] and the [[http://en.wikipedia.org/wiki/Diff%27rent_Strokes unhappy fates]] of its three leading kid actors (Coleman, Bridges, and Dana Plato, who played Mr. Drummond's daughter). As of the current time, Bridges is the last surviving child star from the series among the original threesome (Dan Cooksey joined later, and has avoided the fates of his older co-stars), but it's such stories that the FormerChildStar trope is built upon. Coleman's is parodied in the musical ''Theatre/AvenueQ''.

!!Tropes:
* AnAesop
* AllGaysArePedophiles: Referenced and debunked in "The Bicycle Man" episode. In the VerySpecialEpisode's final scene -- one where the police detective basically answers common questions, as posed by the Drummonds -- Willis remarks that Mr. Horton (the seemingly genial bicycle shop owner with the sinister secret) ''must'' be a homosexual, which the detective refutes quickly.
* AttemptedRape: In a later season episode, Arnold and Kimberly accept a ride in a car from a stranger. He takes them back to his apartment and locks Arnold in another room while he takes Kimberly to his darkroom; their father and the police arrive JustInTime.
** And then there was the child molester who ran the bike shop, and convinced Arnold and his friend to come back into his house for ice cream and shirtless wrestling.
* BigEater: Arnold, apparently.
* BigFancyHouse: The posh penthouse where the Drummonds live.
* BlackmailIsSuchAnUglyWord
* BreakoutCharacter: Arnold Jackson.
* TheCastShowOff: Dana Plato was a trained figure skater, which the producers allowed her to demonstrate in "Family on Ice" (with SpecialGuest Dorothy Hamill).
* CatchPhrase: "Whatchoo talkin' 'bout, Willis?"
** Willis' habitual "Saaaaaaaaaay what?" would qualify as well.
* ChildHater: In "The New Landlord," the titular {{landlord}} decides to ban children from the building, meaning the Drummonds face eviction.
-->'''Arnold:''' Weren't you a kid once?
-->'''New Landlord:''' Nope. I went directly from birth to landlord.
** In "The Woman," a woman who Mr. Drummond wants to marry plans to send the kids away.
* ChristmasEpisode: Two of them; the first was also a ClipShow.
* {{Cloudcuckoolander}}: Aunt Sophia.
* CorporalPunishment: One episode centered around Mr. Drummond saying he'd have to spank Arnold for some misdeed. Willis argued that ''he'' should spank Arnold, because he's "family". And he does.
* TheCouch
* CousinOliver: Sam.
* CrossOver: Several crossovers have ocurred during the series' run. Including three that involved the [=McLean=] Stevenson sitcom ''Hello, Larry'' and a handful involving spinoff ''Series/TheFactsOfLife''. Characters from ''Diff'rent Strokes'' have also crossed over onto ''SilverSpoons''.
* DaddysGirl: Kimberly.
* DeadpanSnarker: Arnold. The other characters have their moments too.
* DemotedToExtra: Willis in the last two seasons was dropped into the background since most of the storylines were focusing on Arnold and his new stepbrother Sam (Maggie's son).
* DomCom
* TheEighties
* FollowTheLeader: ''Series/{{Webster}}''.
* HappilyAdopted: The Jackson brothers (eventually). Also Arnold's friend Dudley.
* HappilyMarried: Drummond and Maggie.
* TheGhost: The Gooch, a bully at Arnold's school.
* GoodParents
* IncestSubtext / FlirtyStepsiblings: Kimberly and Willis had a few moments that could be construed as flirting.
* JerkWithAHeartOfGold: Willis can qualify.
* JiveTurkey: Though not too much.
* JustTestingYou: When Susie tells Arnold that she reads ''The Wall Street Journal'', Arnold says he likes the comics in it. When she says there are no comics, Arnold says he is just testing her.
* {{Malaproper}}: Arnold. An example comes from the season three episode "Drummond's Fair Lady":
-->'''Arnold''' [intending to say "Magna Cum Laude"]: "Hi, I understand you graduated Magna Cum Lousy."
* MouthyKid: Arnold. And to some extent, Willis.
-->"You're a lily-livered weak sister with no guts!"
* NewParentNomenclatureProblem: When Willis & Arnold start living with the man who eventually adopts them, they call him Mr. Drummond. They eventually ask his permission to call him Dad, which he gives (even before he officially adopts them). The explicitly do not call him Papa, which was their name for their biological father.
* NotAllowedToGrowUp: Arnold aged much slower than the rest of the cast. Coleman's kidney disorder meant that the actor never grew above 4' 8''.
* OhCrap: The climax of "The Bicycle Man," when Mr. Horton realizes that he's been found out by the police. When Drummond and a detective start to head for Horton's apartment, Horton says, "Wait a minute … you can't go in there!" but is restrained by the other officer.
* OutOfContextEavesdropping: In an early episode Willis and Arnold (black) plan to run away because they overhear their adopted father (white) saying that black boys should be put with black families, thinking that he didn't want them; but he didn't believe in that, he was telling someone else what a black buttinski said to him before he threw him out.
* PaedoHunt: In live-action episodic television, "The Bicycle Man" was probably the trope codifier.
* ParentExMachina
* PicnicEpisode: Darkly portrayed in Season 6's "The Hitchhikers" (the episode where Kimberly and Arnold accept a ride from a stranger named Bill). While the two are held hostage, Bill – possibly having had problems with trying to pursue relationships with women in the past, as alluded to in the episode's closing scene – tries to get Kimberly to be his girlfriend, and to set the mood brings out a picnic basket and blanket and says that's what they're going to do ... .
* PieInTheFace: "Hooray For Hollywood"
* PoorlyDisguisedPilot: "The Girls' School", which bore ''Series/TheFactsOfLife''.
* PostRobberyTrauma: A 1985 episode saw Arnold robbed at knifepoint, and tries (successfully, for awhile) to supress his deep trauma ... but Mr. Drummond senses otherwise and arranges for a schoolroom exercise to get Arnold's true feelings out in the open.
* PrecisionFStrike : On a show that aired early during prime time, with no swearing or vulgar language whatsoever, hearing Mr. Drummond say "Willis, where the HELL have you been?" was jarring.
* PrenupBlowup: Drummond and Maggie.
* PromotionToOpeningTitles: Maggie and Sam in season 7.
* PutOnABus: Mrs. Garrett, then Adelaide. They both [[TheBusCameBack came back]] for the Drummond and Maggie wedding episode.
** Kimberly, via RealLifeWritesThePlot. Dana Plato, who was pregnant at the time, was not part of the regular cast in the last two seasons, only making occasional guest appearances.
* RearrangeTheSong: In addition to the producers having to recast the role of Maggie [=McKinney=] after moving to ABC, Alan Thicke also had to record a new version of the show's theme song, because NBC owned the copyrights to the original.
* RecurringCharacter: Many. The most frequent is Dudley.
* ReplacementGoldfish: Literally. Arnold's beloved goldfish Abraham dies, so the family tries to hide it from him until they can get a replacement. When Arnold becomes suspicious, and happens to notice Mr. Drummond's will, he jumps to the wrong conclusion and thinks that Mr. Drummond is dying. Arnold notices that the new goldfish "isn't Abraham!"
* SmokingIsCool: In "The Girls' School" episode, the character Blair (the snobby rich girl, played by Lisa Welchel) can be seen puffing on a cigarette; this character trait would be dropped (Welchel is a non-smoker) by the time ''Series/TheFactsOfLife'' made it to series.
** Twisted around in a 1984 episode, where Arnold and his buddy, Dudley, experiment with smoking cigarettes. They get a graphic lesson when Dudley's father reveals he is a chronic smoker and needs a lung operation; the fade-to-black scene showed the man lighting up in the hallway, just after leaving the Drummonds' apartment.
* SpinOff: ''Series/TheFactsOfLife''. The spinoff outlasted its parent show by two years, and had a year-longer run (nine seasons, vs. ''Strokes''' eight).
* SpoiledSweet: Kimberly.
* SuspiciouslySimilarSubstitute: Adelaide Brubaker for Edna Garrett, then Pearl Gallagher for Adelaide.
* ThematicThemeTune: Flirting with ExpositoryThemeTune in the lines "A man is born, he's a man of means / Then along come two, they got nothing but their jeans..."
* TooSmartForStrangers: One of the more infamous examples.
* VerySpecialEpisode: Numerous examples. Most famously "The Bicycle Man" 2-parter.
* WeddingDay
* WithFriendsLikeThese : In certain episodes, it seems like Arnold's friends, even to Dudley, will turn on him in a heartbeat, and on a dime.
* WrongNameOutburst: In the season four episode "Double Date", Phillip suggests that Willis accompany Arnold on his first date, since Arnold is too young to date by himself. Before Willis exhausts all options in finding a date, leading to Phillip's suggestion that he [[ItMakesSenseInContext take Kimberly out instead]], Willis tells Arnold the reason why he's looking for a date with another girl is because he called his girlfriend Charlene the wrong name.
-->'''Willis:''' She's not talking to me on account of the name I called her.
-->'''Arnold:''' What's that?
-->'''Willis:''' [[AccidentalMisnaming Janet]].
** Coincidentally, Charlene was played during that season by a Janet: JanetJackson.
