->''"I can hear the sound of empires toppling."''
-->'''--The Doctor'''

The one that ignores the "sub" in "subtext".

Rowan Williams, Archbishop of Canterbury, referred to this story in his 2011 Easter sermon, on the subject of happiness and joy. [[PeripheryDemographic No, really.]]

The Doctor and Ace visit the human colony planet of Terra Alpha, where unhappiness has been outlawed, and people who can't keep a smile on their face at all times have a tendency to... disappear.

While the Doctor befriends a blues-playing tourist named Earl and Ace meets her GirlOfTheWeek Susan Q, the TARDIS gets a nice pink makeover from the Happiness Patrol. Everyone gets thrown into prison a few times over. Well, into the "waiting zone", that is -- because a happy place like Terra Alpha couldn't possibly have prisons. They also meet the Kandy Man (who bears a striking resemblance to the advertising mascot [[http://images.google.com/images?q=bertie+bassett Bertie Bassett]] -- not deliberate, but the BBC got in trouble from Bassetts all the same), a psychotic killer robot made of candy, whom the Doctor defeats in a CurbStompBattle by sticking its feet to the floor with lemonade. The underground MoleMen and the working class join in the battle against the current regime as well, as does a hapless interstellar census bureau employee, after the Doctor runs circles around him intellectually.

The Doctor goes a bit too far in his investigations, though, and soon comes face-to-face with a very powerful gun. In a rather serious scene for what's otherwise the most perfectly {{camp}} episode in a while, he dares the gunman to shoot him point blank, which causes a HeelRealisation in the soldier and leaves the Doctor able to continue his staged uprising. It all culminates in a sort of song-and-dance number, with the Doctor proclaiming that the oppressed working class people are ''really tremendously happy'' and therefore can't be arrested. The Happiness Patrol is very unhappy about this turn of events. So the Doctor tells them that they should now logically arrest ''each other'' for being glum. Which they promptly do.

The local dictator, Helen A (who bears a [[NoCelebritiesWereHarmed striking resemblance]] to UsefulNotes/MargaretThatcher -- deliberate, WordOfGod would later say) decides to get the hell out before her society comes crashing in on itself. Sadly for her, her gentle husband runs away together with Kandy Man's creator, and the two make off with the only escape pod. ''And'' her mutated rat-dog-thing Fifi is killed using [[ThePowerOfRock The Power of Blues]]. Helen breaks down crying, realising perhaps for the first time that happiness isn't everything.

* AllCrimesAreEqual: Ostentatious public displays of grief, wearing dark clothes, reading depressing poetry (limericks get a pass), and [[GreyRainOfDepression walking in the rain]] are all capital crimes in these parts.
* AmazonBrigade: The Happiness Patrol.
* AnAesop: "There are no other colours, without the blues."
* ArtisticLicenseEngineering: The levers used by the Kandyman to control the Fondant Surprise are made to look as if they have catches at the top that need to be pushed in before the lever can be moved. The Kandyman's actor moves the levers without touching the supposed catches, making it all too obvious that they're dummies.
* AscendedFanon: Played with/inverted. Back in ''Recap/DoctorWhoS16E6TheArmageddonFactor,'' it was heavily implied that this was the Doctor's true name. The audience either ignored or were incredibly pissed off by this, until the Doctor says in this story that it was his college nickname.
* AuthorTract: UsefulNotes/MargaretThatcher is evil incarnate.
* BestServedCold: Ace nearly feeds Priscilla her own wig, but the Doctor nabs her in mid-flight. He barks at Ace to stay frosty or she'll compromise his whole plan -- But he also promises that revenge will be sweet, indeed:
-->'''Ace:''' I want to make them very, very unhappy.\\
'''Doctor:''' ''(Voice drops into a ''[[GutturalGrowler hiss]].'')'' Don't worry, Ace. We will.
* BittersweetEnding: Helen A is finally forced to confront her sadness upon the death of her beloved pet. However, her government is overthrown and the people are free to experience whatever emotions they damn well want, happy or sad.
** In any other series this would be a DownerEnding, the force keeping everyone happy is gone and misery prevails. Naturally ''Series/DoctorWho'' turns it on its head.
* BlastingItOutOfTheirHands: Susan Q disarming Daisy K.
* BondOneLiner: As it's immediately after the vicious execution of a political prisoner, done as a KickTheDog.
** Combined with PreMortemOneLiner. In both cases they're deconstructed: the members of the Happiness Patrol keep coming out with these just before or after they kill someone, but they're all uniformly unfunny, half-witted things like "Have a nice death!" or "You look unhappy about something!" that only serve to further reinforce what smug, sociopathic and terrible people [[EvilHasABadSenseOfHumor with awful senses of humour]] they are.
* BoundAndGagged: In episode 2 Ace is briefly gagged for saying "Up the Killjoys!"
** And Priscilla P in Episode 3.
** And Daisy towards the end.
* BreakingSpeech: The Seventh Doctor continues his grand tradition of beating his enemies down with speeches that deconstruct their flaws and weaknesses, firstly with the sniper he confronts on the rooftops, and then finally Helen A herself: With her empire up in smoke, Helen plans to flee and find a world more receptive to her monomaniacal ideals-- but then, out of the shadows steps the Doctor. "You can't get away, Helen A."
* BroughtToYouByTheLetterS: Helen A has large capital As on the sleeves of her outfit.
* CannedOrdersOverLoudspeaker: Helen A never allows her people a single moment's peace. Her broadcasts seem to take inspiration from ''BraveNewWorld''[='s=] Mustapha Mond.
* ChekhovsBoomerang: While being held captive by the Kandyman, the Doctor manages to freeze him in place with lemonade. Anticipating a second encounter with (now irate) robot, Seven steals an entire bottle of the stuff from Joseph as he's freshening up someone's drink. Yoink.
* ChekhovsGunman: Earl Sigma, the offworlder blues musician.
* ComicallyMissingThePoint: At one point, the Doctor comes across an undercover Happiness Patrol agent who makes a rather cruel game of provoking {{Hope Spot}}s in killjoys he comes across before revealing his true identity with a business card. When he pulls this on the Doctor, upon learning the agent's identity the Doctor cheerfully remarks that the agent might be able to pass on a message to Helen A for him.
* ConspicuousTrenchcoat: Silas P.'s "undercover" garb leaves a lot to be desired. He's wearing a bright pink cardigan under his drab Killjoy disguise.
* ContinuityNod: The Doctor tells Ace that [[Recap/DoctorWhoS11E2InvasionOfTheDinosaurs the Brigadier once saw a triceratops in the London Underground]]. He also mentions again that Theta Sigma was his college nickname.
* CoveredInGunge: In a decidedly non-comedic version -- Helen A's favourite execution method involves large quantities of hot strawberry fondant, either suffocating you or scalding you to death.
* CrapsaccharineWorld: Terra Alpha is an inverted [[Literature/NineteenEightyFour Oceania]]. On the surface, life under the regime is pretty good. Helen A's built over 1000 new factories, has solved the problem of shortages, pipes camp music into every workplace, and has abolished prisons. At night, however, goon squads go around rounding up undesirables and/or blasting them with their fun guns.
* CreatorCameo: Director Chris Clough voices {{F|luffyTheTerrible}}ifi.
* CulturePolice: The eponymous Patrol. A rather creepy use of the trope, as they go beyond enforcing any kind of culture...
* CustomUniform: When she first appears, Susan Q is one of a group of Happiness Patrol mooks, but she's wearing the more elaborate wig of a speaking character.
* CuteAsABouncingBetty: The patrolwomen's "Fun Guns". These are later turned on the enemy when Susan Q. defects.
* DefectorFromDecadence: Susan Q.
* DoesThisRemindYouOfAnything: The story has generated a lot of discussion about the political meanings and agendas behind a lot of what's going on, particularly concerning 1980s politics and gay rights among others; Helen A and her cronies are stand-ins for UsefulNotes/MargaretThatcher and her government, a young woman describing her realization that she was "unhappy" is played as if she was [[ComingOutStory coming out in another sense]] (i.e. a 'closeted' blues fan), and so forth. This might also explain the inaction on the part of Terra Alpha's neighbors: Trevor reveals that his purpose is to take a census of everyone who's disappeared rather, suggesting that the planetary government he reports to would rather make lists of the dead than [[HeadInTheSandManagement do anything to stop those lists growing...]]
** Silas P.'s entrapment of killjoys by blending in among them is a particularly barbed commentary of the police. This tactic is altogether too common with undercover cops looking to cuff 'deviants'.
** Helen A's policy of, shall we say, managing population through extreme force, is reminiscent to some extent of how Margaret Thatcher brought inflation to an all-time low, but at the cost of high unemployment rates: technical success only.
* DrowningPit: It seems the Kandy Man's favourite method of execution was trapping the victim in a tube and filling the tube with fondant, drowning them. The flavour of the fondant varied, Helen A's favourite was strawberry.
* DystopianEdict: No unhappiness!
* EightiesHair: Like you wouldn't believe. The hairstyles of the Happiness Patrol also call to mind feathered hats from {{the forties}}, another homage to film noir.
* EvenEvilHasStandards: Even Daisy K, herself a willing and eager stooge of Helen A's regime, considers Priscilla P an out-of-control fanatic.
* EverythingsBetterWithDinosaurs: They don't appear, but Ace seems to believe this; at the beginning of the episode she's excitedly begging the Doctor if they can go see some.
* EvilChef: The Kandy Man uses confectionery as a means of execution.
* TheEvilGenius: The Kandyman acted as this for Helen A, being her chief torturer and a scientist.
* EvilHasABadSenseOfHumour: The "happy" characters' actual jokes are limited to [[BondOneLiner sadistic mockery of the people they're killing and torturing]].
** Lampshaded with the "prize" for winning the slot machine in the Waiting Zone -- a poorly delivered joke from Helen A -- which the Doctor thoroughly deconstructs with respect to its sheer awfulness.
* ExactWords: The Doctor, posing as a galactic census taker, talks his way into Helen A's office where he finds that everything is above-board and legal. 100% transparency. Yep.
-->'''Helen:''' I think you'll find everyone on Terra Alpha is very happy.\\
'''Doctor:''' Some people on Terra Alpha are very difficult to find.
** Ace completely flubs her rehearsal for the Patrol, as she doesn't sing, dance, juggle, perform magic, or tell jokes, and the only songs she knows are [[TrueArtIsAngsty paeans to suicide]]. When questioned about her talents, the Doctor looks stumped as well, then answers, "She [[DemolitionsExpert makes things disappear?]]"
--->'''Doorman:''' Magic. ''(tics checklist)''\\
'''Doctor:''' Nothing magical about the way ''she'' does it.
* ExtremelyShortTimespan: The Doctor challenges himelf to orchestrate the complete collapse of a ruthless despotic society over the course of a single evening. He does so without any knowledge of the regime's inner workings, having no plan in place, and willingly getting himself arrested. [[BadassBoast And he succeeds.]]
* FascistButInefficient: Terra Alpha is clearly starting to fall apart at the seams when the Doctor gets there, but he manages to press the right buttons to bring down Helen A's government entirely.
* FascistsBedTime: Dusk is the most dangerous time to be out wandering. Andrew Cartmel used this setting as an excuse to shoot the episode with minimal light, contrary to standard BBC procedure.
* FauxAffablyEvil: The Kandy Man. He considers himself a confectionery artist even though his talents are used more for executing dissidents.
* FelonyMisdemeanor: A Type 3. On Terra Alpha, being a 'Killjoy' (i.e. being unhappy) is punishable by death.
* FilmNoir: Despite the gaudy nature of Terra Alpha, the 'outdoor' scenes of the story are all filmed in a consciously film-noir style, with lots of long, dark shadows all over the place. A couple of the male characters wear long coats and wide-brimmed fedoras as well. The Doctor and Earl use music to communicate across the city, and at one point the duo sing/play a few bars from [[{{Film/Casablanca}} "As Time Goes By"]]. Reportedly the episode was originally planned to be in black and white.
* FluffyTamer: Helen A truly loves her snarling pet Fifi.
* FluffyTheTerrible: Helen A's vicious and downright ugly pet Stigorax called Fifi.
* GlurgeAddict: Helen A, to the point where her execution methods involve sweets.
* HairTriggerAvalanche: Fifi is crushed to death when Earl uses his harmonica to cause an avalanche of the unstable crystallized sugar deposits in the pipes.
* HappinessIsMandatory: And if you're not happy, you get the death penalty.
* HaveANiceDeath: In the opening, one of the members of the titular organization even drops the name of this trope as they are executing the first killjoy seen on screen.
-->Have a nice death!
* HeelFaceTurn: After bonding with Ace over their taste in music, Susan Q deliberately lets her escape, and from then on is on the Doctor's side.
* HoistByHisOwnPetard: The Kandy Man is ultimately killed by the very execution method he was in charge of.
** Also, after Susan Q disarms Daisy K by BlastingItOutOfTheirHands.
--->'''Doctor:''' Who taught you to shoot like that?\\
'''Susan Q (points to Daisy K):''' She did.\\
'''Doctor:''' Thank you, Daisy K.
* HomoeroticSubtext: The story is ''very'' easily interpreted as a gay rights allegory. The TARDIS gets painted pink, Ace and her GirlOfTheWeek had to have some rather LesYay lines cut just to get past the BBC censors, and the story ends with two men running off together.
* ImplicitPrison: The waiting areas are specifically ''not'' prisons ... but step over the line that marks the edge of the area, and "you're a dead man".
* ImprobableHairstyle: At first glance, Helen A looks to be wearing a hat -- but no. That is a combination 80's perm/ponytail with [[SkunkStripe whitewalls]] and topped off with a big pink stripe(!).
* IronicEcho: "Happiness will prevail." (smile)
* JumpingOffTheSlipperySlope: Helen A protests that the secret police and summary executions only "came later" -- after a few stubborn citizens refused to embrace her philosophy. By now, the "routine disappearances" number over half a million(!).
* KillerRobot: Made of candy.
* LadyLand: A subtle example (at least relatively, given many examples of the trope); most of the characters with power and authority in the story are women (the Happiness Patrol, for example, is composed primarily or entirely of women), and it's heavily suggested that Terra Alphan society is biased in favour of women instead of men; at one point the two male snipers gripe that women always get the better jobs -- and guns. It avoids most of the usual "utopian AuthorTract" tropes often associated with the trope, in that Terra Alpha is hardly a better place because the women are in control instead of the men. ''(insert real world analogy here)''
-->'''Alex:''' ''(grousing)'' Don't see any women doing roof duty. Women always get the better jobs.\\
'''David:''' Women always get the best guns.
* LadyInRed: Helen A. is wearing what appears to be chair upholstery with sleeves.
* LetMeAtHim: Priscilla stands over the cooked Harold quipping about his fate. This causes Ace to go aggro, and the Doctor snatches her before she does something stupid.
* LetNoCrisisGoToWaste: Before Helen A took over, Terra Alpha had its share of problems. One of the planet's biggest hurdles was overpopulation. The census bureau has strict protocols for address that issue, but Helen smilingly assures them her own methods are far more "effective."
* LetsSeeYOUDoBetter: Gilbert M all but says this about people who think confectionery is easy.
* LoveHurts: Between Helen A's ruthless StepfordSmiler persona and determination to be utterly happy at all costs, and her strangely bitter-yet-wistful retort upon the Doctor's accusation that her perfect world is a world without love that "I always thought love is overrated", [[FreudianExcuse it's implied that something like this might be lurking somewhere in Helen A's backstory]].
* LowSpeedChase: The Patrol's go-karts don't seem to travel much faster than walking pace, which makes the sequence where the Doctor and Ace steal one in order to escape slightly ridiculous.
* MadArtist: The Kandy Man is a mad culinary artist.
* MagicalNegro: Earl Sigma.
* MauveShirt: The moment his exposition is concluded, Harold gets electrocuted by the same slot machine whose jokes he denigrated earlier. Apparently, Helen opted to wipe out the whole clan rather than suffer another traitor.
* MoleMen: The Pipe People are the original inhabitants of Terra Alpha who, following colonization, have retreated into the complex of pipes that run throughout the city.
* MotiveRant: Helen A delivers one at the end during her confrontation with the Doctor.
* MyCard: Silas is only allowed to slap on the handcuffs once you accept it.
* MyRuleFuIsStrongerThanYours: The Doctor arranges for the protesting killjoys to gather ''en mass'' in Forum Square, knowing that this will trigger a crackdown from the authorities, and two teams of the Happiness Patrol are sent to terminate the killjoys with prejudice. When the hit squad gets there, however, the killjoys have shed their dark clothes, cast aside their funeral dirge and are now firing off party steamers and dancing like its 2099 -- and thus are no longer killjoys, meaning the Happiness Patrol can't touch them. And to really sweeten the cake, when the second team arrives they find the first team milling about confused, glum and generally acting like killjoys -- and promptly arrest them.
-->'''Doctor:''' And their logic tells them, twisted though it be, [[RhymesOnADime that as such they have no power over me!]]
* ANaziByAnyOtherName: Earl sadly hums on his harmonica, only to frantically burst into polka music when Priscilla drives past, slapping a pink sticker on his lapel.
* NervesOfSteel: The Doctor knows the difference between a lean killer and a coward raining down death from rooftops. He has the audacity to sneak up on some snipers, puff out his chest and dare them to kill him honorably. And then snatches the gun away, when they hesitate.
* {{Newspeak}}: There are no prisons on Terra Alpha, only "waiting zones"! --''[-but cross that line and you're a dead man.-]''
** Helen A's administration is fond of euphemisms. They aren't carrying out purges, merely "controlling" the population with "disappearances." Also, when Helen A meets with Trevor Sigma and the Doctor, she coyly informs Trevor that she's adopted the Galactic Census Bureau's recommendations... but not their guidelines. Trevor is too naive to pick up on this, but the Doctor is not impressed. He later confronts Helen A as she's arranging an execution and throws the euphemism back at her:
-->"And which member of the population are you attempting to 'control' today?!"
* NoCelebritiesWereHarmed: Helen A is basically a sci-fi StepfordSmiler version of UsefulNotes/MargaretThatcher.
* TheNotSoHarmlessPunishment: Standard punishments are doled out by the Kandy Man, who loves "happy" and typically sweet-themed executions, like having molten-hot sugar poured down your throat until you either suffocate or are boiled alive.
* OneLetterName: All the Terra Alphans have a personal name followed by a single letter indicating their social rank.
* OurMonstersAreWeird: The Kandyman, a psychopathic torture robot made of candy.
* PassThePopcorn: Helen A. munches candies while observing her televised executions.
* PersecutionFlip: The conservatively-dressed "killjoys" are the oppressed minority, while Helen A's shock-troopers all resemble painted drag queens.
* PhotoOpWithTheDog: Once captured (again), Ace refuses to cooperate with Helen A by joining her Patrol. Cue Joseph, rushing in with a flashbulb camera. We cut to a recruitment poster with Ace's stunned expression plastered on it.
* PoliceState: The eponymous patrol used their "fun guns" and pink uniforms to suppress anyone seeming miserable or unhappy, whom they labelled "Killjoys". Some were executed by means of deadly sweets...
* [[ThePowerOfRock The Power of Blues]]
* PunchClockVillain: A running theme in the Cartmel era. The snipers on the rooftops are depicted almost as blue-collar blokes, grumbling about their long hours and viewing the protesters below as mere specks. When the Doctor gets in their faces and thrusts his chest toward the gun barrel, he shames them out of complacency.
* RightHandAttackDog: Although Helen A's pet Fifi initially appears to a RightHandCat, she is actually a very efficient predator, as seen at the end of the serial when Helen A sends her down the pipes to wipe out the pipe people and other dissidents hiding there.
* RippedFromTheHeadlines: Helen A was intended to satirise Margaret Thatcher, saying things like, "I like your initiative, your enterprise" while her secret police rounded up dissidents. Also, the Doctor persuades "the drones", who toil in the factories and mines, to down tools and rise up in revolt, an echo of the miners' strikes and printers' disputes during Thatcher's first two terms in office.
* RoboticPsychopath: The Kandy Man is extremely sadistic and cruel.
* SaltAndPepper: The Doctor and Earl playing their respective instruments in the sewers, with their upturned hats sitting side-by-side.
* ScrewThisImOuttaHere: Gilbert M. and Joseph C. Together.
* ShoutOut:
** The use of letters as surnames recalls Josef K in ''TheTrial''.
** Ace relates the plot of Mark Dinning's "[[TeenageDeathSongs death disc]]" song "Teen Angel".
** Susan Q, the Happiness Patrol member who does a HeelFaceTurn, is probably named in reference to Dale Hawkins's R & B song "Susie Q".
* SlasherSmile: By Helen's edict. "And don't forget, when you smile, ''I want to see those teeth.''"
* SociopathicSoldier: Priscilla P
* StepfordSmiler: An entire culture of them, led by a UsefulNotes/MargaretThatcher NoCelebritiesWereHarmed who enforces this way of life with the death penalty.
* SympathyForTheDevil: Helen A weeping over her beloved pet Stigorax, Fifi, as it dies in the gutter. This just minutes after she's been deposed and her consort has betrayed her to the rebels (and skipped off [[RockBottom with another man!]]). This is all a bit harsh, even for Ace, but it shuts the book on the Happiness Patrol for good.
-->'''Ace:''' Shouldn't we do something, Professor?\\
'''Doctor:''' ''(ice cold)'' 'Tis done.
* TakeMeToYourLeader: The Doctor, working under a self-imposed time limit, figures the quickest way to liberate Terra Alpha is to get himself arrested. Amusingly, this [[CantGetInTroubleForNuthin takes some doing]] on his part.
* TakeThat: Sheila Hancock confirmed that her performance was based on Thatcher, whom she "hated with a passion".
* TalkingYourWayOut: Faced with an [[SociopathicSoldier enthusiastic sniper]], the Doctor simply goes up and demands that the sniper shoot him, end his life; the sniper gives up. It's a [[SugarWiki/MomentOfAwesome CMOA]], but it also ends up making [[http://www.youtube.com/watch?v=-Rn4Vv3dH9Q the Doctor look more a little... creepy]] -- both snipers are really unnerved at the end. Creepy or not, however, the Doctor still talks a fanatic into doubting and rejecting all his convictions under the space of a minute while having a gun pointed at him the whole time, which is impressive to say the least.
** The whole scene was used as the basis of the first AudioPlay/BigFinishDoctorWho audio starring Seven and Ace, [[Recap/BigFinishDoctorWho005TheFearmonger "The Fearmonger"]].
* {{Thoughtcrime}}: Policed by the Happiness Patrol.
* TranquilFury: The Doctor keeps his game face on while being detained by Priscilla and her cronies -- but underneath the sly expression, he's clearly fuming with rage.
* UncannyValleyMakeup: All the Terra Alpha characters. Gilbert M and Joseph C take theirs off while running away together, which doesn't actually make it any less homoerotic.
* VelvetRevolution: The Doctor brings down an entire Fascist regime overnight.
* VillainousBreakdown: Indeed, the whole crux is the Doctor trying to provoke one. If Helen A loses her composure, her whole philosophy is discredited. By Episode Three, Helen is clearly going to pieces over the state of things but, to her credit, somehow manages to maintain her stiff upper lip... until she discovers her pet dog Fifi, the only thing she has ever loved, is dead. Cue harmonica.
* WeaksauceWeakness: The Kandy Man can be rendered immobile with a quick spray of lemonade to his feet.
* WhatMeasureIsAMook: A despairing Susan Q. admits she's nowhere near sadistic enough to be Happiness Patrol material, and thus expendable. "She won't shed any tears over me. Let's face it, no one will. Even if they wanted to, [[GallowsHumor they wouldn't be allowed.]]"
