** A more comical example occurs in "Tree House"; Drake forgot to put a door to enable him and Josh to leave when necessary while building their neighbor a new treehouse. Once Josh finds out, he's barely holding his anger at this display of idiocy:

* ''Series/DrakeAndJosh'': In "Josh Is Done", after Drake has taken advantage of Josh for the final time, Drake attempts to apologize for his actions to Josh after school. [[RejectedApology Josh rebuffs the apology]] in a calm manner and tells Drake that he's simply done with him, even giving him a TheReasonYouSuckSpeech while still retaining his equanimity. Needless to say, Josh lets fate do all the talking as he improves his own life while Drake's gradually falls apart.

** Delenn usually expresses anger with an imperious TheReasonYouSuckSpeech. But during the Drakh attack in ''Lines of Communication'', when she said "Who said we were leaving?", you knew the Drakh were in trouble. When her Whitestar moves to block the fleeing Drakh mothership from entering a jump gate, she finally gives the incredibly chilling two-word command ''"End this"''. Spoiler –-  it doesn't go well for the Drakh.

Spoiler – it doesn't go well for the Drakh.

* In the season one finale of ''Series/BlueBloods'', Frank Reagan confronts the men who murdered his son Joe, demanding in a frighteningly calm voice to know which one of them actually pulled the trigger. He was equally calm--but no less enraged--when warning Erin's attacker "Get your hands off my daughter."

** Wesley as well, in late season 5, though that's also just total despair on his part after [[spoiler:Fred dies]].

** Xander is a surprising example of this trope, given his usual goofy temperament, but threaten someone he cares about and it doesn't matter how much stronger than him you may be--he will calmly inform you that he will kill you (see his conversation with Buffy after she got Willow kidnapped or his conversation with Angel at the hospital). It is telling that none of the super-powered characters he has threatened have ignored the threat. The man can be scary when he wants to be.

** Subverted after he gains full control of the Intersect: even once he can access his kung-fu and other skills whenever he needs to, he's ''still'' fundamentally Chuck: sensitive, kind, pacifistic, and only beating your ass when you give him no other choice (and often ''still'' giving you a chance to back down in the process). It's only in one third-season episode where Chuck is given an experimental pill by Casey that suppresses his emotions where he truly enters this state. While he's certainly ''pissed'' after [[spoiler:Shaw kills his father]], he's still his normal and emotional self. But under the effects of the drug Chuck becomes an ice-cold machine while defending [[spoiler:Casey's ex-fiancee]], and it's absolutely ''terrifying'' to see.

*** [[Recap/DoctorWhoS30E6TheDoctorsDaughter "The Doctor's Daughter"]]: Faced with his own daughter's dead body, the Doctor picks up the gun that killed her, holds it against the head of the man who fired it, and delivers the spine-chilling [[spoiler:"[[PunctuatedForEmphasis I. Never. Would.]]", destroying that man's support with three words]]. If you pay attention to the background music as he holds the guns, guess what it is? Drums. That's right — the Doctor was nearly pushed into becoming the Master Mark 2.

* In one first-season episode of ''Series/ExtremeMakeoverHomeEdition'', Ty Pennington is quietly furious when he learns that his four designers have endangered the entire timeline of the makeover because of a {{side bet}}. The designers have paired off, men versus women, to see who can design the best room; however, they've taken to ''sabotaging'' each other by the time Ty discovers the bet. His eyes are cold and his voice is unusually hard, which is unsettling coming from [[BewareTheNiceOnes such a normally nice guy]]. The designers take heed and never, for the rest of the show's run, do anything like this again.

** Upon viewing a clip where coach Dabo Swinney refuses to entertain the notion of paying student athletes because "there's too much entitlement already"--keeping in mind that he's making millions off the kids, and has trademarked his own name to make even more money--John brightly smiles and informs the audience that "Dabo Swinney" is an anagram of "Soybean Wind", a not-so-subtle call to action for his audience to humiliate Swinney on social media ([=#SoybeanWind=]).

** DS Matt Devlin has a similar moment with Alesha's rapist--the man whines that Matt is hurting him when he handcuffs him and Matt ''smiles'' as he calmly informs him, "Yeah, I know", strongly implying that he himself would like to take him somewhere and beat the crap out of him.

** Throwing Joseph out in season 6 of the former show. He was screaming as usual, right until Joseph started slinging actual threats. After that, he became deadly calm, and with a much lower voice blasted him for having no respect and threw him out. He didn't back down or even twitch even when Joseph got right in his face, threatening to take it outside.

* In the ''Series/{{Sherlock}}'' episode "[[Recap/SherlockS02E01AScandalInBelgravia A Scandal in Belgravia]]", the title character returns to 221B Baker Street and notes a number of scratches and small bloodstains on the wall, which he realizes were due to Mrs. Hudson clawing at it frantically as she was forcibly dragged upstairs. He looks up with a DeathGlare. Upon entering the room, he finds a number of American agents holding her at gunpoint. He coolly tells Mrs. Hudson to "stop sniveling" and shows little outward change in demeanor; however, his trademark SherlockScan of both Mrs. Hudson and her captor shows, among other things, indications that the man had given her a nasty backhand across the face, and the on-screen text that would normally show Sherlock's various deductions about him is replaced by cross-hairs pinpointing potential targets--notably, several of them are ''not'' [[ColdBloodedTorture kill shots]]. He then disarms him and coolly calls him an ambulance for injuries he hasn't sustained...yet.

** John's prone to this too. This is what happens if you get him pissed - especially if you screw with his friend. It ''definitely'' ends badly for you. [[BewareTheNiceOnes Very, very, badly. It doesn't help that he's capable of actually KILLING you in this mode]].

** In the ''Series/StarTrekDeepSpaceNine'' episode "For the Uniform", Captain Sisko, normally fairly vocal--[[ScaryBlackMan and often physical]]--in his frustration, has for months been dealt several deeply personal blows by the Maquis. Towards the end of the story arc, he is finally pushed too far, and his speech becomes very measured and serene... while ordering his crew to get ready to ''use chemical weapons!'' [[spoiler:It may or may not have been an act.]]

** Data is used to play with this trope as a plot point in "Descent Part I". Liberated Borg attack his away team early in the episode, and as Data kills one of them, he feels anger--and, disturbingly, pleasure. He later recreates the incident on the holodeck in an attempt to recapture the feelings but fails after several tries. It becomes rather morbidly funny to watch Data casually and dispassionately dispatch the holograms; repeating his angry words from the battle with a completely flat affect, and not even sparing a second glance as the drones slump dead to the ground.

* ''Series/TerminatorTheSarahConnorChronicles'': Cameron, being an almost {{emotionless|Girl}} {{robot|Girl}}, can ''only'' enter Tranquil Fury when she gets angry--usually when someone [[BerserkButton lies to her]].

* Kim from ''Series/YesDear'' did this once in one episode -- by swinging a bat and vandalizing the truck of a contractor with inefficient work performance ''while whistling to herself''.

** Wash’s wife, Zoe, is great at it though. She rarely gets visibly furious or raises her voice or anything like that, but the fury can be felt just the same. Mostly it’s the tone of her voice rather than yelling or visibly reacting much. She once got Jayne, who’s the biggest, strongest guy on the crew with a DeathGlare and a quiet “You want to leave this room now.” Her only exception is when Wash dies in the film and HeroicBSOD sets in.

* Wash of ''{{Series/Firefly}}'' was supposed to become deadly serious when things got serious. As the DVD commentary explains, that plan did not survive contact with Alan Tudyk. However, despite the jokey lines, Wash ''is'' usually extraordinarily calm, beyond even DeadpanSnarker.

* In the season one finale of ''Series/BlueBloods'', Frank Reagan confronts the men who murdered his son Joe, demanding in a frighteningly calm voice to know which one of them actually pulled the trigger. He was equally calm--but no less enraged--when warning Erin's attacker "Get your hands off my daughter."

* ''Series/BigLove''. After the boyfriend of Bill Hendrickson's daughter informs him that TheDragon of his nemesis has been stalking her, Bill is next seen casually approaching the man's hotel room. The only hint of what's about to come is him removing his watch. The man opens the door, Bill pushes his way in, and we only get to hear the NoHoldsBarredBeatdown that he's receiving, along with Bill yelling, "Don't you ''EVER'' go near my daughter again!"

** To be fair, the Goa'uld did the same to thousands of other hosts and have slaughtered billions across the galaxy.

*** [[Recap/DoctorWhoS35E12HellBent "Hell Bent"]]: After [[spoiler: arriving on Gallifrey]], [[CharacterFilibuster the Doctor]] [[OOCIsSeriousBusiness doesn't speak for hours or perhaps days]]... he just gives his trademark KubrickStare constantly. Everyone walks on eggshells around the man known as [[NamesToRunAwayFromReallyFast the Oncoming Storm]] and dare not cross his LineInTheSand, not even with ARTILLERY, as it's quite obvious that after [[spoiler:the Time Lords caused the death of Clara and imprisoned him for 4 billion years in a GroundhogDayLoop always ending in his death]], he is '''[[UpToEleven beyond]]''' pissed. When the President ([[spoiler:Rassilon the Eternal]]) finally shows up to speak with him, the Doctor, never raising his voice, never raising his fists, simply says, "Get off my planet." For sheer terror of what [[TemptingFate disobeying the Doctor]] might bring, the military forces the President to.

** [[Recap/DoctorWhoS37E3Rosa "Rosa"]]: In her first confrontation with Krasko, the Thirteenth Doctor spends most of the conversation barely treating him as a threat, mainly addressing him with playful disregard. But the moment he threatens to kill her and her friends if he sees them again... she tells him, with steely eyes and an icy tone, "Don't threaten me." In that moment, it's goodbye to the adorable Labrador puppy, and hello to the Oncoming Storm.

* ''Series/DadsArmy'': In "High Finance", Wilson, learns that [[spoiler:Hodges]] would write off a £50 debt owed to him in rent by Mrs Pike ([[OldMoney Pre-decimalization, remember]]) if she'd be "nice" to him. Cue Wilson walking calmly from one end of the table to the other:

* ''Series/DadsArmy'': In "High Finance", Wilson, learns that [[spoiler:Hodges]] would write off a £50 debt owed to him in rent by Mrs. Pike ([[OldMoney Pre-decimalization, remember]]) if she'd be "nice" to him. Cue Wilson walking calmly from one end of the table to the other:

* ''Series/AgentsOfShield'': This is Melinda May's default status. Is telling that, when she grab a Berserker Staff that make people go ballistic, her mood barely changes.

---->'''Delenn:''' This is ambassador Delenn of the Minbari. Babylon 5 is under our protection. Withdraw. Or be destroyed.\\

* In ''Series/TheBigBangTheory'', when prepping Howard to speak with her father about the matter of him signing a pre-nup:

* ''Series/BlackAdder'': Richard IV is mostly a BloodKnight whose [[ChewingTheScenery diet mostly consists of nearby bits of scenery]], and played by Britain's pre-eminent bellower, '''Creator/BrianBlessed'''. However, the one moment when he is most frightening is when Edmund has been appointed Bishop of Canterbury, and Richard takes him aside and calmly informs him that if he crosses the Crown in any way, Richard will personally do to him what God did to the Sodomites. The effect is absolutely bone-chilling.

* In the ''Series/BostonLegal'' episode "Truly, Madly, Deeply", Denny is forced to defend a man who raped and murdered a 13-year-old girl. During a conversation between the two of them, his client not only shows no remorse of any kind for his actions, but for added {{Squick}} he tells Denny that he thinks he did the child a ''favor'' by killing her before she fell victim to a venereal disease ''he gave her''. Denny reacts by calmly discussing ways that they could use this claim as a basis for their legal defence, while simultaneously rummaging through his bag, producing a gun and then shooting him in both legs.

** Really, this is Willow’s go to regardless. Whether she’s threatening to beat a 200 pound soldier to death with a shovel, taking command of the Scooby Squad in their darkest hour, or blasting around hell gods, her tone when furious ranges from false cheer to a deadpan monotone.

** Xander is a surprising example of this trope, given his usual goofy temperament, but threaten some one he cares about and it doesn't matter how much stronger than him you may be--he will calmly inform you that he will kill you (see his conversation with Buffy after she got Willow kidnapped, or his conversation with Angel at the hospital). It is telling that none of the super-powered characters he has threatened have ignored the threat. The man can be scary when he wants to be.

** All of the Doctor's incarnations have gone into this mode at least once. As he gets angrier, he tends to go from smiling to annoyed scowling to shouting to steely-eyed gazing.
*** Especially since some of the Doctor's incarnations can get ''annoyed'' very easy. Wacky to snippy is no big deal. Wacky to shouting is usually because he ''expected better'' from whoever did a bad thing. But when an irredeemable foe has ''really'' gone and done it, the loud personality shuts off. This is when ''anything'' goes in order to stop you... and maybe [[FateWorseThanDeath he won't stop at stopping you]].

*** Another impressive showing from the Ninth Doctor is the end of [[Recap/DoctorWhoS27E7TheLongGame "The Long Game"]], when he approaches Adam with a DeathGlare after Adam's attempt to steal future technology nearly doomed them all.

*** [[Recap/DoctorWhoS30E6TheDoctorsDaughter "The Doctor's Daughter"]]: Faced with his own daughter's dead body, the Doctor picks up the gun that killed her, holds it against the head of the man who fired it and delivers the spine-chilling [[spoiler:"[[PunctuatedForEmphasis I. Never. Would.]]", destroying that man's support with three words]]. If you pay attention to the background music as he holds the guns, guess what it is? Drums. That's right — the Doctor was nearly pushed into becoming the Master Mark 2.

** [[YouWouldntLikeMeWhenImAngry Don't make the Twelfth Doctor]] angry. Unfortunately for everyone, Twelve's default setting frequently hovers around [[TameHisAnger already annoyed]]. As per the purview of all Doctors, [[FateWorseThanDeath killing you will be the kindest thing he can do to you,]] [[ThouShaltNotKill and he hates]] [[AndIMustScream killing.]]

** [[Recap/DoctorWhoS37E3Rosa "Rosa"]]: In her first confrontation with Krasko, the Thirteenth Doctor spends most of the conversation barely treating him as a threat, mainly addressing him with playful disregard. But the moment he threatens to kill her and her friends if he sees them again... she tells him, with steely eyes and an icy tone, "Don't threaten me." In that moment it's goodbye to the adorable Labrador puppy, and hello to the Oncoming Storm.

** When Jon tries to save his brother [[spoiler:Rickon, Rickon is arrowed in the back and killed]] by Ramsay in "The Battle of the Bastards" just as Jon and [[spoiler:Rickon]] are just about to reach each other. A distraught Jon Snow doesn't utter a single roaring fury and instead maintains a zen-like calmness, though verging on DeathSeeker levels. And when he finally gets his one-on-one against Ramsay, he still doesn't yell or scream. With said tranquil fury, Jon charges against Ramsay's arrow attacks with a discarded shield. The only time he does emote is when [[NoHoldsBarredBeatdown he's beating the ever loving shit out of Ramsay]].

* ''Series/{{JAG}}'': This is the case whenever Admiral Chegwidden gets angry or really pissed-off.

* Played with hilariously in an episode of ''Series/MyNameIsEarl''. While on court ordered happy pills, Joy goes from bitch to annoyingly calm, even putting up with some obnoxious neighbors who park their trailer right next to hers... until they tag Earl Jr. with a beer can. Even the pills couldn't turn off her MamaBear instincts. She explains in a scary happy voice that she's gonna come back in a few days, when the chemical calm wears off, and thrash them in several unpleasant ways. They decide to move before she does.

** Similarly with Reese's GuileHero partner, Finch, who goes progressively more icy, calm, and speaks in a CreepyMonotone the closer someone get to pressing his BerserkButton, and those who have been unlucky/stupid/evil enough to do so will be calmly informed just exactly how he will [[FateWorseThanDeath destroy their lives]] just before doing so. The greatest example of which is when [[https://www.youtube.com/watch?v=F-6YGCnRYqA Finch declares war on Samaritan.]]
** At the end of the series Shaw corners Blackwell, who had [[spoiler:killed Root]] a couple episodes earlier. She starts out by monologuing how she would have killed him without a second thought years ago, until she met teammates who changed her. After Blackwell begs mercy by claiming that they would not want her to kill him, she calmly confirms his words, but then retorts [[spoiler:they're dead, before shooting him]].

** Jan from ''Series/JukenSentaiGekiranger'' is at his strongest when he is calm. [[spoiler:This is shown when he defeats Rio one-on-one even after Rio had gained a extremely powerful PowerUp in one of the [[SugarWiki/MomentOfAwesome greatest fights in sentai history.]]]]

** The "lame duck" incident, also from ''Hell's Kitchen'', in which one team utterly embarrassed themselves with a terribly done duck breast. In front of a couple that had just married that day. After the couple left, Gordon didn't raise his voice once, but was visibly livid as he told them to "Get. Out. My. Sight."

** When he learns that Fisher has been violent with his sister-in-law Jackie, Dan calmly puts on his coat, leaves the house and off-screen beats him. He stays calm and serene as his cop buddies show up to arrest him after Fisher lays charges of assault on him, even joking around with them as he gets handcuffed and taken to the station. ''Do not hurt Dan's family.''

* In ''Series/{{Selfie}}'', this is PlayedForLaughs with the character of Terrence. When confronting his boss and disapproving father in law, he mentions how he is "the angriest he's ever been". But he sounds perfectly cheery and like his normal voice, and he doesn't seem that bothered by Mr. Saperstein's comments ("What if I were to say you weren't good enough for my daughter and you never will be?" "I'd strongly disagree and ask if there is anything else I can help you with?"), so Saperstein decides to change him from being a "floater" in the office to working in customer service.
* ''Series/TheSentinel''. Despite the fan fiction, in canon Jim Ellison tends to be usually calm and rarely raise his voice. However, when you DO tick him off...

* In the ''Series/{{Sherlock}}'' episode "[[Recap/SherlockS02E01AScandalInBelgravia A Scandal in Belgravia]]", the title character returns to 221B Baker Street and notes a number of scratches and small bloodstains on the wall, which he realizes were due to Mrs. Hudson clawing at it frantically as she was forcibly dragged upstairs. He looks up with a DeathGlare. Upon entering the room, he finds a number of American agents holding her at gunpoint. He coolly tells Mrs. Hudson to "stop sniveling" and shows little outward change in demeanor; however, his trademark SherlockScan of both Mrs. Hudson and her captor shows, among other things, indications that the man had given her a nasty backhand across the face, and the on-screen text that would normally show Sherlock's various deductions about him is replaced by cross-hairs pinpointing potential targets--notably, several of them are ''not'' [[ColdBloodedTorture kill shots]]. He then disarms him and coolly calls him an ambulance for injuries he hasn't sustained... yet.

'''Lestrade:''' And exactly how many times did he fall out a window?\\

*** In "Heroes pt. 2". After the death of [[spoiler:Janet Fraiser]], the leader of a documentary team comes to try and ask Daniel about it. Without changing expression, or the volume or tone of his voice, Daniel begins slowly advancing on him, repeatedly telling him to leave, the unspoken threat being that if he didn't by the time he got there, Daniel would beat the ever loving crap out of him.

** In the ''Series/StarTrekTheOriginalSeries'' episode "The Omega Glory", while the crooked starship captain Tracy holds Kirk and Spock captive, he contacts the ''Enterprise'' to tell them that the landing party has been infected and advises them not to beam down anyone else. Jim tries to call out and is knocked out by one of Tracy's henchmen. In that instant Spock grabs one of the spears blocking him and is only stopped by the phaser on Jim’s unconscious body. His face looks calm but one can see the burning anger in his eyes.

** Data is used to play with this trope as a plot point in "Descent Part I". Liberated Borg attack his away team early in the episode, and as Data kills one of them, he feels anger--and, disturbingly, pleasure. He later recreates the incident on the holodeck in an attempt to recapture the feelings, but fails after several tries. It becomes rather morbidly funny to watch Data casually and dispassionately dispatch the holograms; repeating his angry words from the battle with a completely flat affect, and not even sparing a second glance as the drones slump dead to the ground.

*** He's royally pissed off at Roland Pryzbylewski for pistol-whipping a 14 year old while accompanying Herc and Carver on unsanctioned field interviews. He doesn't raise his voice once when he instructs Prez what to do which includes falsifying a police report, claiming that the kid attacked him and he hit him in self defense when the reality was that Prez pistol-whipped him because he "pissed him off".

* ''Series/DrakeAndJosh'': In "Josh Is Done", after Drake had taken advantage of Josh for the final time, Drake attempts to apologize for his actions to Josh after school. [[RejectedApology Josh rebuffs the apology]] in a calm manner and tells Drake that he's simply done with him, even giving him a TheReasonYouSuckSpeech while still retaining his equanimity. Needless to say, Josh lets fate do all the talking as he improves his life while Drake's own life gradually falls apart.

*** When he threatened Cersei after discovering that she was torturing Ros, and when he promised to geld Joffrey if he insisted on a bedding at Tyrion's wedding. Further, when Joffrey calls him a "little monster", he replies with:

** Tywin very calmly establishes his power by sending Joffrey to his room. All without raising his voice.

** Sandor is a particularly brutal example. He rarely shows any emotion while slaughtering people. When he rescues Sansa from would-be rapists he does so with a grim, emotionless expression while ruthlessly gutting the rioters.

* ''Series/TheHandmaidsTale'': June shows this as she's forced to appear with the Waterfords when the Waterfords make their televised appeal for the infant Nichole's[[note]]Nichole is June's infant daughter, a child June was forced to bear for Fred and Serena Waterford in Gilead as their handmaid. However, Nichole's biological father isn't Fred, but Nick -- June's LoveInterest -- as Fred is infertile.[[/note]] return from Canada. June had risked everything to get Nichole smuggled into Canada where Nichole would be safe and free, out of Gilead, and she is currently staying with June's husband, Luke.

** Even if you're part of Dan's family. When he blasts Darlene and Becky for trying to manipulate Roseanne (treating her to a spa day in order to get permission to go to an out of town concert) he never raises his voice, but when he says, "I'm ''very'' angry", you believe it.
** Maybe even more chilling, in the episode referenced above, Roseanne calmly tells Fisher:
--->There's something you need to understand. I am ''way'' more dangerous than Dan.

** John's prone to this too. This is what happens if you get him pissed-especially if you screw with his friend. It ''definitely'' ends badly for you. [[BewareTheNiceOnes Very, very, badly. It doesn't help that he's capable of actually KILLING you in this mode]].

*** Not long after Sha're is first taken by Apophis to be his queen's host, Sam and Daniel encounter an incubator full of Goa'uld larvae. Sam suggests sparing them because, [[IfYouKillHimYouWillBeJustLikeHim if they killed the defenceless, they'd be no better than the Goa'uld]]. Daniel, quite calmly, accepts her reasoning...and then destroys the tank by firing several bursts into it. His expression remains serene and neutral the entire time, and even afterwards he's unrepentant. Sam is utterly shocked. This is gentle, see-the-enemy's-point-of-view Daniel showing no mercy to the enemy's equivalent of babies with a tranquility that borders on DissonantSerenity, all because of what the Goa'uld did to his beloved wife.

** In ''Series/StarTrekTheOriginalSeries'' episode "Plato's Stepchildren" the Platonians used their mental powers to humiliate Kirk and Spock as Dr [=McCoy=] watches, forcing them to sing and dance like court jesters. Spock was forced to dance a tango around Kirk's body, his feet perilously close to his captain's head. When they were released from control Spock had to take a moment to control his emotions:
*** (The dialogue below was said with Spock’s usual lack of expression. Which makes the words even more chilling.) Getting a Vulcan angry is NOT a good idea.

** In the ''Series/StarTrekTheOriginalSeries'' episode "The Omega Glory", while the crooked starship captain Tracy holds Kirk and Spock captive, he contacts the ''Enterprise'' to tell them that the landing party has been infected and advises them not to beam down anyone else. Jim tries to call out and is knocked out by one of Tracy’s henchmen. In that instant Spock grabs one of the spears blocking him and is only stopped by the phaser on Jim’s unconscious body. His face looks calm but one can see the burning anger in his eyes.

** In the ''Series/StarTrekDeepSpaceNine'' episode "For the Uniform", Captain Sisko, normally fairly vocal--[[ScaryBlackMan and often physical]]--in his frustration, has for months been dealt several deeply personal blows by the Maquis. Towards the end of the story arc, he is finally pushed too far, and his speech becomes very measured and serene...while ordering his crew to get ready to ''use chemical weapons!'' [[spoiler:It may or may not have been an act.]]

** When Worf realizes that Duras murdered his lover in the episode "Reunion", he briskly but calmly leaves the crime scene and goes to his quarters. While there, he tosses his baldric aside and grabs his bat'leth. He pauses at the door, and after a moment's thought, removes his combadge. It is at this point that it becomes clear that Duras is about to die.

* ''Series/TheWestWing'': "[[Awesome/TheWestWing I am not frightened. I'm gonna blow them off the face of the earth with the fury of God's own thunder]]." Don't mess with anyone who President Bartlet likes. In fact, don't mess with Americans, period. Leo manages to talk him down though, showing that Bartlet was angry, but hadn't gone insane.
** One of the most iconic West Wing moments is when President Bartlett goes into RageAgainstTheHeavens (literally, he's in a church talking to God)/Tranquil Fury mode and starts shifting between ''Latin'' and English. Yes, Bartlett is cussing out God in ''Latin''!

* In ''Series/WolfHall'', Mark Rylance plays Thomas Cromwell in this manner. He is totally calm when he tells a friend not to pray God to avenge Cardinal Wolsey's death because "I'll take it in hand", equally so when he tells William Brereton it was a mistake to threaten him. There's no denying that the wrath behind that bland demeanor will be deadly.
* Kim from ''Series/YesDear'' did this once in one episode -- by swinging a bat and vandalizing the truck of a contractor with inefficient work performance ''while whistling to herself''.

** Delenn usually expresses anger with an imperious TheReasonYouSuckSpeech. But during the Drakh attack in ''Lines of Communication'', when she said "Who said we were leaving?", you knew the Drakh were doomed... and when her Whitestar moves to block the fleeing Drakh mothership from entering a jump gate, she finally gives the incredibly chilling two-word command ''"End this"''. Spoiler – it doesn't go well for the Drakh.
