->''"Come and knock on our door...\\
We've been waiting for you...\\
Where the kisses are hers and hers and his,\\
Three's company, too."''

Iconic late-'70s RoommateCom/slapstick sex farce/comedy of errors series. Frequently dismissed as the archetypal JiggleShow, it's also marked by clever writing, strong performances and fantastic physical humor. Based on the BritCom series ''Series/ManAboutTheHouse'', it originally aired on Creator/{{ABC}} from 197784.

The premise: in order to share an affordable apartment with two lovely young ladies, [[BrainyBrunette Janet Wood]] (Joyce [=DeWitt=]) and [[TheDitz Chrissy]] [[DumbBlond Snow]] (Suzanne Somers), cooking student [[HandsomeLech Jack Tripper]] (Creator/JohnRitter) must pretend to be gay around Stanley Roper (Norman Fell), the repressed, bigoted {{landlord}}. Roper, in turn, frequently finds himself fending off the advances of his good-natured but sexually frustrated wife Helen (Audra Lindley), who knows Jack's secret but likes him and the girls enough to keep mum. Complications are introduced through a variety of misunderstandings and mishaps, often caused by the thinking-impaired apartment mates or their cumbersome friends.

Everyone in this series suffers from GenreBlindness at one point or another, which is expected considering the show is essentially a comedy of errors. The show launched the careers of Ritter and Somers, and revived that of Creator/DonKnotts (who joined the cast as new landlord and wannabe-swinger Ralph Furley after the Ropers left for [[Series/TheRopers their own series]] following the third season).

Codified, if not actually created, [[MistakenForIndex an entire set of plot tropes]] based on silly misunderstandings and leaping to conclusions. Creator/LucilleBall was a huge fan of the show thanks to its pitch-perfect use of sitcom tropes and physical comedy, and even appeared to host a ClipShow.

In later years, it's almost more famous for the [[TroubledProduction behind-the-scenes issues]] with Suzanne Somers' contract dispute: she demanded top billing for being MsFanservice despite John Ritter having always been the main character, and after Somers made shooting next to impossible, producers retaliated by showing her in no uncertain terms just how unwelcome she was (see below for details). Overall, the series endured many cast changes, nasty backstage disputes and overall changing tastes in television to become one of the most fondly-remembered (and frequently emulated) shows of the era.

!! "Come and knock on our tropes..."

* ACupAngst: Janet; one episode revolved around her deciding to get breast implants.
* AbsenteeActor: Chrissy was largely missing from the fifth season, due to contract fights with Suzanne Somers. They squeezed around it by having her appear in the last two minutes of every episode on the telephone so that her roommates could recap the day's events. Somers was made to film these scenes several hours removed from the rest of the cast in a completely empty studio with a crew that was visibly angry at having to work late. When the season was over, Somers' contract was quietly let go and Chrissy was PutOnABus forever.
* AfraidOfDoctors: Mr. Furley refuses to go see a doctor about his aching back because he doesn't trust them. When he finally decides to see one, the doctor turns out to be Jack in disguise, trying to impress his grandfather who he lied to about being a doctor.
-->'''Mr. Furley:''' I don't trust doctors. They stick in their needles and take out your money. They're all crooks, why do you think they wear masks?
* AfterShow: ''Three's a Crowd'', not to be confused with the inexplicable and deplorable Creator/ChuckBarris GameShow.
* TheAllegedCar: The rust covered Ropermobile. We hear about in an episode in which Roper tries to sell it to Jack and the girls, and actually see it in action in the pilot episode of ''Series/TheRopers''.
* AnnoyingLaugh: Chrissy's snort.
* AscendedExtra: Larry started out as a guest star, but got more appearances over time and [[PromotionToOpeningTitles a promotion]].
* BankToaster: Parodied. Janet says that she's so terrible at accounting, her bank offered her an alarm clock to move her account elsewhere.
* BeachEpisode: Setting the show in Santa Monica gave the producers the perfect excuse to [[WalkingSwimsuitScene parade the female leads around in skimpy bathing suits]].
* BedsheetLadder: The trio tries to escape with one when trapped in the bedroom by diamond thieves, but they accidentally throw the whole sheet out the window.
* BitchInSheepsClothing: Felipe, Jack's jealous assistant chef at Angelino's who smiles to his face and pretends to be a loyal worker but is always trying to get him fired so he could be head chef.
** Becomes somewhat subverted later on, when the two actually do become friends. Helps when Jack gets his own restaurant and is no longer competition.
* BreakingBadNewsGently: Jack lies to his grandfather about being a doctor to impress him, but it backfires when his grandfather visits and wants to see him at work in his office. When Terri refuses to sneak him into an empty office at the hospital, he attempts to guilt her into cooperating by calling his grandfather and pretending to leave a message telling the truth. He drags out the message, beginning by asking the hotel operator to ask his grandfather to sit down before reading it, until Terri finally agrees.
* BunnyEarsLawyer: Despite his clumsiness in just about every other setting, Jack is a very talented chef.
* CampStraight: Jack. This certainly helps when it comes to playing gay.
* CasanovaWannabe: Several of them, including Larry, Mr. Furley, and often Jack himself.
* {{Catchphrase}}:
** Jack: "Oh lordy, lordy, lordy..."
** Mr. Furley: "Now hear this!..." and "Open up! It's R.F.!"
* CensorSteam: Mentioned
-->'''Mr. Furley:''' You mean Lana saw me in the bathtub?
-->'''Chrissy:''' You don't have to be embarrassed. The little bubbles hid everything.
** Parodied when Jack walks in on Chrissy in the bath and tells her she needs more bubbles when she kicks him out.
* ChainedHeat: Jack and Chrissy accidentally handcuff themselves together, and Jack has a date to keep.
* ChivalrousPervert: Jack Tripper
* ChristmasEpisode: Season 2's "Three's Christmas".
* ClipShow: "The Best of ''Three's Company''", hosted by Creator/LucilleBall.
* CommutingOnABus: Cindy does this in Season 6 before falling victim to ChuckCunninghamSyndrome.
* TheCouch
* Cougar: Lana definately fits this description.
* CureYourGays: Mr. Furley thinks his friendship with Jack did the trick when, in the finale, he moves in with a woman.
* DatingServiceDisaster: Jack, under the alias Duke Bradford, tries computer dating and is matched up with Janet, who is using the alias Desiree. After they find out what happened, they decide to continue the date anyway.
* ADayInHerApron: Inverted. The girls are used to Jack doing the cooking for them. But on one occasion when he's not around, they are forced to feed themselves. HilarityEnsues.
%% Zero Context Example * DidTheyOrDidntThey
%% Zero Context Example * DinnerWithTheBoss: ''So many examples.''
* DistractedByTheSexy: The original TitleSequence has Jack running his bike off a beachfront sidewalk and tumbling into the sand as a result of this.
* DIYDisaster: According to Helen, Stanley once fixed their freezer so that it defrosts every time the toilet is flushed.
* DumbBlonde: Chrissy and Cindy; Janet when she got her blonde wig.
* EarlyInstallmentWeirdness: Most noticable with Chrissy, who during the very first few episodes is not quite TheDitz that she [[CharacterizationMarchesOn later develops into]].
* EndOfEpisodeSilliness
* ExecutiveMeddling: In universe when Jack is invited to a televised cooking demonstration. A producer moves around the items Jack placed cue cards in, causing him to mess up the demonstration.
* {{Farce}}: The TropeCodifier for sitcom farce; many ordinarily non-farcical sitcoms will [[ShoutOut explicitly reference]] this series when they make forays of their own into the genre.
* FakeTwinGambit: Jack pretends to be his own twin, "Austin" the macho cowboy, in order to fool Mr. Furley so he can date his niece.
* FakingTheDead: Jack pretends to be dead to escape a man who is determined to kill Jack for looking at his girlfriend. Believing it to be a ruse, he goes to see Jack's body and apologizes for terrorizing Jack. Jack gives himself away by habitually replying, "That's OK."
* FashionDissonance: The show's from TheSeventies, so there's bound to be a bit of this. Especially pronounced are Mrs. Roper's assortment of caftans and Mr. Furley's polyester-intensive "swinger" outfits.
* FauxYay: Jack pretends to be gay so he can live with two female roommates.
* FlamboyantGay: Even when Jack is pretending to be gay, he really doesn't act any different, but Mr. Roper and Mr. Furley both seem to be convinced that Jack is this trope. However, whenever Jack accidentally gives some indication of his true sexuality, he does invoke the trope a bit in order to MaintainTheLie.
* {{Flanderization}}: In the first season, Chrissy was a little naive but not exactly stupid. Second season on, she almost became TooDumbToLive.
* GenreBlindness: Borders on [[ContractualGenreBlindness contractual]].
* GeorgeJetsonJobSecurity: Mr. Angelino and Jack.
* GirlOfTheWeek: Subverted for Jack, as he never got far with any of them.
* GrandFinale: The two-part "Friends and Lovers", which has Janet getting married, Terri moving to Hawaii, and Jack moving in with a new girlfriend.
* HappyEndingOverride: One early episode has Chrissy's mother visit, with her being afraid of her parents knowing that a man is living with her and Janet, so Jack has to stay out of the apartment while she is there, and when she decides to spend the night, Jack has to hide in Janet and Chrissy's room. [[spoiler: But they find out that the Roper's had told her about Jack and was okay with him living with them, as she felt they needed a man to protect him in the neighborhood they live in.]] A later episode has Chrissy's father coming over, and it turns out that while her mother was okay with the situation, her father, a minister, did not know.
* HaveAGayOldTime: This series probably marks the point where the word 'gay' passed from Hollywood and Theatrical slang into the popular lexicon. [[LampshadeHanging Lampshaded]] in an episode in the middle of the series:
-->'''Judge:''' Are you gay?
-->'''Jack:''' Well, I can be sad sometimes, too.
%% Zero Context Example * HeadTiltinglyKinky
* HeelFaceRevolvingDoor: Felipe
* HighClassCallGirl: Chrissy's friend Darlene happens to be one, but Chrissy doesn't know. When Janet and Jack find out, they try to hide it from Chrissy to avoid disappointing her (since Chrissy looks up to Darlene highly.) They lie and convince Chrissy she is an airline stewardess, which becomes a problem when Chrissy decides it would be fun to go to work ''with'' Darlene to see what her job is like.
* HilariousOuttakes: A quite infamous one where Jack falling onto a bed while wearing shorts resulted in one of John Ritter's testicles briefly being visible. It was digitally covered up in syndication, to which Ritter had the priceless response that they should alternate both versions, since "Sometimes you feel like a nut and sometimes you don't."
%% Zero Context Example * HitMeDammit
* HowManyFingers: Jack and Janet administer this test to Chrissy after she falls and hits her head in the bathtub. They are shocked to hear Chrissy reply "five" when Jack is only holding up two fingers, but Chrissy clarifies that two fingers are straight up, and three are folded behind Jack's hand.
* IAteWhat: One episode had Mr. Roper [[DogFoodDiet eat some dog food]] he mistook for a stew Jack had whipped up. He reported it was much better than his wife's cooking and asked Jack to give her the recipe.
** In a later episode Jack bakes a sawdust cake for what he thinks is a party for Eleanor, the former roommate (it's actually for him). He tries to get back the fake cake from the guests, but Roper has already eaten some. He asks his wife why she can't bake something that good....
** In a Season 6 episode, Cindy is mixing something in a bowl when Jack comes along and eats it before she can tell him it's glue.
* IdiotBall: Everyone at some point, usually thanks to mishearing a conversation or misinterpreting a situation.
* IHaveToWashMyHair: A lady who Mr. Furley has a date with uses this excuse to cancel their date. Janet suggests Mr. Furley ask her to go out the next day, to which Mr. Furley replies that she told him that was the day she ''dries'' her hair.
* ImprobableFoodBudget: The main characters often have trouble paying the rent, but they always have plenty of delicious food. It's justified by Jack being a cooking student and needing the practice (blowing a significant portion of his budget on food) and, in fact one of the reasons the girls accept him as a roommate is the food.
* InformedAbility: Jack was supposedly a boxer in the Navy, but the closest we ever see him come to actually using this skill is when he calls a tough guy's bluff and the situation ends without a fight. It's hard to imagine him being that coordinated, given how clumsy he usually appears.
** This is explained in a later episode when Jack ends up in a boxing match. Larry wonders why someone who boxed Golden Gloves would be afraid and Jack admits he lost every fight he was in.
* InnocentCohabitation: Not that the main characters [[RunningGag can really convince anyone]] that is the case. The show was largely a response to the growing trend in TheSeventies of nonsexual, opposite-sex roommates, which just a decade before was almost unheard of. Which brought up an amusing DoubleStandard when Jack finds out that a girl he is seeing is living with two men, and he ''refuses'' to believe that it's strictly innocent.
* JerkWithAHeartOfGold: Larry.
* JiggleShow : Probably one of the TropeCodifier examples. Chrissy is frequently shown jumping up and down in celebration, for no apparent reason. Jack likes watching her and even comments that she cheers better than anyone he knows.
* TheKlutz: Jack and Cindy.
* LocalHangout: The [[AdjectiveAnimalAlehouse Regal Beagle]]
* LockedInTheBathroom: Jack's date locks herself in the bathroom while Jack is having a food critic over for dinner. Unable to convince her to come out, Mr. Furley, attempts to [[SkeletonKeyCard unlock the door with his credit card]], which she takes when he pushes it through the crack.
* MeanBoss: Frank Angelino is this for Jack.
* MistakenForGay: The whole case between Jack and the two landlords.
* MinorInjuryOverreaction: Jack receives a minor cut at work and Phillipe accompanies him to the hospital. Although Jack is already nervous about the injury, Phillipe's comments cause him to barge into the treatment room while the doctor is treating a more serious patient and demand to be seen.
* MrsRobinson: Lana Shields, an attractive middle-aged neighbor who had the hots for Jack in a few season 4 episodes. Part of the reason the character was [[ChuckCunninghamSyndrome quietly dropped]] was due to Ritter's complaints about the implausibility of Jack spurning her attentions.
* NakedPeopleAreFunny: Season 3's second episode has Janet and Mrs. Roper attending a protest rally at a nude beach. After the police break it up, the two have to run home without their clothes on.
* NoEnding: One episode featured Mr Furley secretly taking in a cat, which a little girl lost that the roommates have been trying to help find for her. At the end of the episode all that happens is the girl sees Mr Furley holding the cat, and then cue credits.
** When this episode plays in syndication, TheTag is cut for time. In it, the building inspector appears and sees the three kittens the roommates have collected. Mr. Furley says he is taking them straight to the pound, and the building inspector, aghast, takes the three kittens home with him. The little girl says she'll try raising goldfish instead, and leaves. [[WhatHappenedToTheMouse But we never do find out what happened with the original kitten.]] It's never spoken of again in the series.
* NotWhatItLooksLike: Often happens when Mr. Furley or Mr. Roper walks in at a bad time.
* OneDialogueTwoConversations: This is pretty much how every wacky situation happens. In one episode Mr. Roper overhears Chrissy talking about removing a wart on her finger and believes she is getting an abortion.
** In another, Janet plans to redecorate their bedrooms, but Jack and Chrissy think she's hiring a man to father her baby.
** In a third episode, Jack plans to remove a tattoo he got while he was drunk. Janet thinks he's getting a vasectomy.
* OutOfContextEavesdropping: As mentioned above, this premise was the plot of roughly 2/3s of the episodes. Here's an example that Ralph Furley overheard in the bathroom:
--->'''Jack:''' Okay, Chrissy, I'll get in the tub with you then we can get it on.
--->'''Chrissy:''' Stand next to me, I'll show you what to do.
--->'''Jack:''' This isn't exactly the first time I've ever done this.
--->'''Chrissy:''' Maybe so, but girls are better at this than boys.
--->'''Jack:''' Come on, Chrissy, [[Music/ElvisPresley a little less talk and a little more action]].
--->'''Chrissy:''' Okay, you do your part and I'll do mine. ''[pause]'' I don't think it'll reach.
--->'''Jack:''' Of course it won't. You've got to unfold it first.
** [[spoiler:They're hanging up a shower curtain.]]
* PhoneyCall: The phone rings while Jack is pretending to talk to Irene.
** Jack does this again when he pretends to call his grandfather's hotel to leave him a message informing him that he's not actually a doctor. Janet grabs the phone and discovers he called Larry.
* PieInTheFace: "The Bake-Off"
* PoorlyDisguisedPilot: Season 3's "An Anniversary Surprise", which sets up ''Series/TheRopers'' by revealing that Stanley has sold the apartment building so he and Helen can move to a new, nicer place across town.
** An offshoot is the actual pilot to ''The Ropers'' itself ("Moving On"), which is often shown as part of ''Three's Company'' in syndication complete with the ''Three's Company'' opening and closing credits.
** The end of the final episode [[FromTheAshes sets up the premise]] for ''Three's a Crowd''.
* PorkyPigPronunciation: Stanley tries to type up a bill of sale for his car and realizes the U key is missing from his typewriter.
--> '''Stanley:''' How am I supposed to spell "automobile" without U?
--> '''Helen:''' C-A-R.
* PornStash: Mr. Roper has one. He calls it "putting them somewhere convenient".
* ThePratfall: Jack Tripper was legendary for these.
* TheProblemWithPenIsland: Janet once misread the word ''therapist'' on a business card as "''the rapist.''"
* PunnyName:
** [[UsefulNotes/JackTheRipper Jack Tripper]]. Also a MeaningfulName, as Jack has a bad habit of [[TheKlutz tripping and falling over the couch]]. And tripping while trying to get out of the tub near the beginning of the first episode - while telling Chrissy and Janet his name.
** The character's name in ''Man About The House'' was "Robin Tripp", a pun on [[ThoseWackyNazis Ribbentrop]].
** Chrissy's given name is "Christmas Noelle Snow".
** Janet Wood worked in a flower shop.
* PutOnABus: The Ropers, Chrissy, and Cindy.
** TheBusCameBack: The Ropers returned for one season 5 episode following the cancellation of [[Series/TheRopers their spinoff show]].
* RealLifeWritesThePlot: Suzanne Somers was holding out for more money so the studio just called her bluff -- because they couldn't technically fire her due to the terms of the contract, they instead let it run out by [[WrittenInAbsence moving her away]].
* RecurringCharacter: Lana Shields, Mr. Angelino, Filepe, Dean Travers, Reverend Snow, bartenders Jim and Mike.
* RequiredSpinoffCrossover: Jack, Janet, Chrissy, and Larry all appeared on ''Series/TheRopers''. Larry also turns up in a ''Three's a Crowd'' episode.
* RoommateCom: The show revolves around Jack Tripper and his two female roommates, Janet Wood and Chrissy Snow, who is later replaced by her cousin Cindy followed by Terri Allen. Their apartment is owned by married couple Mr. and Mrs. Roper, who later got their own sitcom and were replaced by Ralph Furley. Jack originally had to lie about his sexual orientation to Mr. Roper since Mr. Roper would not allow him to move in with the two women if he were straight.
%% Zero Context Example * ScotchTape
* ShesGotLegs: Joyce [=DeWitt=] had a ''gorgeous'' set of gams and always wore pantyhose on the show, refusing to appear bare-legged even when her character Janet was supposedly [[ModestyTowel naked under a towel]]. She even appeared in several [[http://www.youtube.com/watch?v=jhGPELYfXgM commercials]] for L'eggs.
* SkeletonKeyCard: Jack's date gets upset at Jack and [[LockedInTheBathroom locks herself in the bathroom]]. Mr. Furley tries to help by unlocking the door with his credit card, but Jack's date takes the card when he slides it through the crack between the door and the frame.
* {{Sleepwalking}}: Chrissy starts doing this in one episode.
* SneezeOfDoom: Jack fakes his death in an episode to escape from a jealous boyfriend who's intent on revenge after spotting him looking at his girlfriend. He needs to resist sneezing while in the casket after one of his "mourners" brings flowers.
* SpinOff: ''Series/TheRopers'' had the title characters moving into a swanky townhouse; ''Three's a Crowd'' followed Jack's adventures with his new restaurant and live-in girlfriend. Both were based on spinoffs of the British version. Neither was particularly successful.
* SpiritualSuccessor: ''Series/ModernFamily'', which also has most of its comedy revolve around wacky misunderstandings, also features gay characters (except they're [[CharacterizationMarchesOn actually gay]]), and is just as popular as ''Three's Company'' was back in the day.
* StarvingStudent: This is why Jack moves in with the girls. He's a starving cooking school student.
* StronglyWordedLetter: In "Out on a Limb," a food critic comes into Jack's Bistro, takes a quick bite, and leaves, causing Jack to worry that the critic hated the food and is going to give him a bad review. Larry suggests that Jack send the critic an angry letter, with Janet typing it. Larry starts the letter with "Dear Sleazebucket," and it goes downhill from there.[[note]]Jack and Janet ask Larry how he could come up with such a hostile letter off the top of his head like that. He says it was easy because he got the exact same letter that morning at the used-car dealership.[[/note]] Of course, the critic loved the food and gives Jack a great review, so the gang has to [[IrrevocableMessage retrieve the letter before the critic can see it]]. Oh, and Janet actually toned it down.
** In another episode Mr. Furley says that he's written many strongly worded letters to his brother complaining about not having enough money to maintain the building. He then says that if his brother doesn't shape up soon he's [[DeliveryNotDesired going to start mailing them]].
* SuspiciouslySimilarSubstitute: Cindy for Chrissy. The only real difference between them was that Cindy was a klutz. Terri is an aversion. Though a blonde, she was quite intelligent.
* SupremeChef: Jack, presumably. It would certainly explain why they keep him around instead of finding a female roommate (or, you know, an actual gay guy).
* SweaterGirl: Jack was often distracted by sweater girls on this show, resulting in {{Freudian Slip}}s on several occasions: "You need to separate the yolk from the sweater." "I just came to button up my coffee."
* ThematicThemeTune / TitleThemeTune: "Down at our rendezvous / Three is company, too!"
* ThrowingOutTheScript: Mr. Furley does this to the over-the-top sentimental speech Larry wrote for him to read at the trio's moving away party.
* TookALevelInJerkass: After trying on a blonde wig and seeing the attention she gets, Janet starts to more and more embody the DumbBlonde. Problem is, unlike Chrissy or Cindy, she gets downright obnoxious and insulting. Fortunately, she has a HeelRealization in the end and cleans up her act.
* TransAtlanticEquivalent: of the series ''and'' both {{spinoff}}s!
%% Zero Context Example * TwoTimerDate
* TheUglyGuysHotDaughter: Bart Furley is rather short. His daughter is full-sized and very attractive.
** An early episode had Jack getting involved with Mr. Roper's hot niece.
* UnresolvedSexualTension: There were multiple episodes throughout the series giving off hints that Janet and Jack might have a thing for each other, but nothing ever really came of it, and in the finale they both end up marrying other people.
* VowOfCelibacy: In one episode Jack [[TheBet makes a bet with the girls]] that he can refrain from having relations with women for a certain amount of time. The girls then try to find ways to make him lose the bet.
* WatchingTheReflectionUndress: In one epsiode Jack and Chrissy are temporarily sharing the bedroom normally used by Chrissy and Janet, but there's a mouse in the room that Janet is afraid of. Chrissy tells Jack to turn away so she can get into bed, so he turns and looks right at a mirror which shows him Chrissy in her skimpy nightie.
* WeddingDay: The first half of the two-part series finale depicts Janet's wedding to Phillip, a guy she met at the flower shop.
* WhatDidIDoLastNight: In one episode Jack is having a noisy party. Mr. Roper arrives to tell him to quiet down, ends up joining in the festivities, and wakes up the next morning [[BedmateReveal in bed with Jack]].
* YouAreNumberSix: One scene has the girls gossiping with Mrs. Roper about various tenants having affairs with each other, and they refer to all the tenants by their unit number.
