->''"If somebody you knew, whether they were a criminal or a window washer, constantly talked about "the rules", you would never want to hang out with this fuckin' nitwit, would you? You're washing the window and the fucker says, 'Rule #1. No streaks.' What an annoying dude. Get him away from me."''
-->-- '''[[http://outlawvern.com Vern]]''', reviewing ''Film/TheTransporter''

He's in a dangerous or uncomfortable situation with other people who are less experienced or trustworthy than him, and he wants to make some things clear. So he bluntly declares a numbered list of "rules" for the situation. Beginning, of course, with Rule Number One, and following it with Rule Number Two, and so forth. The implication of setting out these rules, and providing a semblance of structure by numbering them, is that they are resolute and unquestionable, and that breaking these rules will lead to dire consequences.

Another situation is conveying advice or admonishments, such as with the MentorArchetype or OldMaster. In this case the rules could be 'don't use the DangerousForbiddenTechnique' or 'always believe in yourself'. They are likely to include RuleZero: "I'm always right."

One version of this trope [[MemeticMutation became so popular]] that 90% of these will be StockShoutOuts to ''Film/FightClub'' -- "Rule Number One of [X]: ''You do not talk about [X]''" and/or "Rule Number One: [Y]. Rule Number Two: '''[Y]'''!"

ThereAreNoRules is a inversion, though that itself is sometimes called "Rule #1" nonetheless. This can then be subverted by having other rules follow which are actually restrictive.

The ThievesGuild most often has each of its members adhere to certain numbered rules.

For the [[Literature/{{Discworld}} other]] Rule Number One, see BadassGrandpa.

Characters who live by The Rules are obviously on the Lawful side of CharacterAlignment, but there's nothing stopping them from being LawfulGood or LawfulEvil. In fact, expect the latter from the ObstructiveBureaucrat who can cite any Rule that justifies him/her not doing anything remotely reasonable or helpful.

[[folder: Literature ]]

* In ''DirkGentlysHolisticDetectiveAgency'', Richard is breaking into his girlfriend's apartment when he receives a mysterious phone call describing "the rules of breaking into an apartment". Rule number one is "never answer the phone".
* In Terry Pratchett's novel ''Discworld/ThiefOfTime'', Lu-Tze often reminds people about Rule One. Unfortunately for them, not everyone gets the message. Rule One is: [[spoiler: "Never act incautiously when confronted by a [[OldMaster little bald wrinkly smiling man]]!"]] Then there's Rule Nineteen, which is "Never forget Rule One, and ask yourself why it was invented in the first place."
* ''Literature/TheActsOfCaine'': Matthew Stover's Caine has three rules. They really boil down to "I'm the boss and can kill you to maintain this authority", and serve more to operate as a [[BadassCreed coercive threat than as a code of behaviour]]. If he ever asks you "What's Rule Two?", then you are in '''[[PreMortemOneLiner deep shit]]'''.
* ''Literature/{{Sharpe}}'': Richard Sharpe has three rules for the men who serve under him: 1) Don't get drunk without permission. 2) Don't steal unless it is from the enemy or you are starving. 3) When it is time to fight, fight like bastards.
* ''Literature/VorkosiganSaga'': Miles Vorkosigan's cousin Ivan, critiquing someone else's covert op that almost failed miserably: "You play games like that with the big boys, you'd better make damn sure you win, Miles says. Rule One. And there is no Rule Two."
* In ''Literature/AliceInWonderland'', the King of Hearts reads out Rule Forty-two: "All persons more than a mile high to leave the court."
--> `Well, I sha'n't go, at any rate,' said Alice: `besides, that's not a regular rule: you invented it just now.'

--> `Then it ought to be Number One,' said Alice.
* From ''[[Literature/MassEffectRevelation Mass Effect: Revelation]]'':

[[folder: Live Action TV ]]

* [[Franchise/StarTrek Ferengi]] are immensely fond of quoting Rules of Acquisition.
-->First Rule of Acquisition: Once you have their money, you never give it back.
-->33rd Rule of Acquisition: It never hurts to suck up to the boss.
-->45th Rule of Acquisition: Expand or die.
-->Unwritten Rule of Acquisition: When no appropriate rule applies, make one up.
** [[PlayingWithATrope Played with]]: the first Rule of Acquisition was presented as #162 - to create a demand for #1 through #161, and according to Quark's vision, they're only rules because the "Guidelines of Acquisition" doesn't have the same selling power.
** A complete list of the rules (canon and non-canon) can be found [[http://memory-alpha.org/wiki/Rules_of_Acquisition here]].
** Ensign Robin Lefler, who appeared in one episode of ''Series/StarTrekTheNextGeneration'', "The Game", had "Lefler's Laws", a list of rules she made up for herself. She still uses them when she becomes a main character in ''StarTrekNewFrontier''.
** The [[{{AlienNon-InterferenceClause}} Prime Directive]] is the Federation's RuleNumberOne.
* ''Series/DoctorWho'':
** "[[Recap/DoctorWhoS24E4Dragonfire Dragonfire]]": The Doctor welcomes a new companion:
--->'''The Doctor:''' Do you fancy a quick trip around the twelve galaxies and then back to Perivale in time for tea?\\
'''Ace:''' Ace!\\
'''The Doctor:''' But, there are three rules. One: I'm in charge.\\
'''Ace:''' Whatever you say, Professor.\\
'''The Doctor:''' Two, I'm not the Professor, I'm the Doctor.\\
'''Ace:''' Whatever you want.\\
'''The Doctor:''' And the third... Well, I'll think up the third by the time we get back to Perivale.
** In the ''Literature/DoctorWhoNewAdventures'' novel ''Set Piece'' Ace, seemingly left with no choice but to kill the Doctor to save the universe, flashes back to this conversation (and occasions when the Doctor had to make similar decisions) and decides that the third rule -- ''her'' rule -- is "No-one deserves to be sacrificed".
** In the new series, the following is said to companions, not that they ever listen:
--->'''The Doctor:''' Rule One: Don't wander off.
** River Song's personal Rule One is, "The Doctor lies." And it turns out [[spoiler:she was given that rule by the Doctor]], along with Rule 7: "Never run when you're scared," Rule 27: "Never knowingly be serious," and Rule 408: "You should always waste time when you don't have any. Time is not the boss of you."
** In [[Recap/DoctorWhoS29E8HumanNature "Human Nature"]], the Doctor leaves a set of 23 numbered rules for Martha to follow while he's transformed into a human and unaware of his true identity. In actuality, there were only about five instructions in the script (as Martha fast-fowards through most of them), and David Tennant [[http://www.youtube.com/watch?v=SEVK3j4wJvU hilariously ad-libbed dialogue for the skipped parts]].
** In the ''Literature/DoctorWhoNewAdventures'' novel, the list the Doctor gave Benny only has nine rules on it. The five Tennant actually gives are there, including the one about pears.
** The Doctor's friend [[Characters/DoctorWhoExpandedUniverse Iris Wildthyme]] has "Wildthyme's Law Rule Number One", which changesh every time to something pertinent to the current situation. Among other things, this rule has been "Grab the nearest bottle and hope for the best" and "A girl never knows when she may need to get the party started."
* ''Series/BuffyTheVampireSlayer'':
** "The first rule of Slaying: Don't die!" Buffy breaks this one ''twice'' and is still around to be scolded by Giles.
** In "Real Me" Buffy states the Rule Number One of living in Sunnydale is "[[VampireInvitation Do not invite blood-sucking dead people into your home!]]" Buffy breaks that rule too.
* ''{{NCIS}}'': Gibbs' various rules, cited by the characters throughout the show. A flashback revealed them to have been inspired by his future wife on the day they met. Kate and Ziva both requested that Gibbs write the rules down, only to be told that most of the rules are for day-to-day tasks. Rules in the forties are reserved for emergencies.
** TWO rules are apparently number one (and two rule number threes), likely due to an oversight on the part of the writers, although later confirmed to have been intentional. This was lampshaded when the female version of Gibbs from CGIS told [=McGee=] HER rule number one and suggested he write it down. [=McGee=] replies that rule number one has been taken, twice. The other one was inherited from Mike Franks, Gibbs' boss when he first became an NCIS Agent. Mike Franks told Gibbs that he didn't need a list of rules; he only needed "Three Golden Rules". It has not been revealed which of the rules are Gibbs' and which are Franks, nor has the second Rule Number 2.
** [[LabRat Abby Scuito]] has her own Rule 1: Don't lie to Abby.
* ''Series/RobocopTheSeries'' had an episode featuring Murphy's old partner, a cop with a set of rules amounting to "no vigilantism". When said cop was brainwashed, Robo brought him back by making him say his rules. A minute later, he was [[RedemptionEqualsDeath killed with a rocket launcher]].
* Unproduced 2008 TV pilot ''Captain Cook's Extraordinary Atlas'' [[http://tvwriting.googlepages.com/pilotschool (available here)]] mentions three rules that were followed by Captain James Cook when exploring the more fantastic areas of the Earth, and that were supposed to be followed by subsequent "navigators".
* In one of the most well-known ''Series/{{MASH}}'' episodes ("Sometimes You Hear the Bullet" - the show's first WhamEpisode and its GrowingTheBeard moment), Henry Blake tells Hawkeye:
-->'''Col. Blake:''' "All I know is what they taught me at command school. There are certain rules about a war. And rule number one is young men die. And rule number two is, doctors can't change rule number one."
* In ''Series/RedDwarf'', Kryten would often quote the Space Corps Directives, with a number each time. Rimmer would try to do the same, but get the numbers wrong; for example, quoting Directive 34124, which Kryten informed him was "No officer with false teeth should attempt oral sex in zero gravity."
* ''Film/FightClub'' is parodied in the ''Robot Club'' episode of ''{{Spaced}}'':
-->'''Robot Club Leader:''' Gentlemen, welcome to Robot Club. The first rule of Robot Club is, you do not talk about about Robot Club. The second rule of Robot Club is, YOU DO NOT TALK ABOUT Ro? wait, I? got that wrong. ''[Unfolding a crumpled up piece of paper and pushing up his glasses]'' The second rule is, no smoking.\\
'''Tim:''' Why aren't we allowed to smoke?\\
'''Mike:''' Shh, we're not allowed to talk about it.
* ''Series/MontyPythonsFlyingCircus'' reads out the faculty rules of the Philosophy Department of the University of Woolamaloo:
--> "Rule one - no pooftahs. Rule two, no member of the faculty is to maltreat the Abbos in any way whatsoever - [[NotCheatingUnlessYouGetCaught if there's anybody watching]]. Rule three - no pooftahs. Rule four - I don't want to catch anyone not drinking in their room after lights out. Rule five - no pooftahs. Rule six - ThereIsNoRuleSix! Rule seven - [[OverlyLongGag no pooftahs]]. That concludes the reading of the rules, Bruce."
* In ''Series/TheAndyGriffithShow'' episode "The Big House", Barney Fife lays down the law for two new inmates at the jail:
--> '''Barney:''' "Now, here at the Rock we have two basic rules. Memorize them, so that you can say them in your sleep. The first rule is: Obey all rules. Secondly, do not write on the walls, as it takes a lot of work to erase writing off of walls."
* The same gag appears in ''Series/{{Porridge}}'', only with the rules in the opposite order. According to Mr. Mackay, there are only two rules in Slade Prison. Rule number 1: Do not write on the walls. And rule number 2: Obey all the rules.
* Harry taught ''Series/{{Dexter}}'' a code to control his psychopathic tendencies. It had whole sections to make sure he only went after bad guys, but as he tells [[spoiler: James Doakes]] toward the end of season 2 in response to the suggesting that he turn himself in, RuleNumberOne was always Don't Get Caught. According to Harry, that was the point of the whole endeavor, keeping Dexter alive; thus it's the first rule. [[spoiler: Of course, no one wants anyone, even oneself, to know that he's turned his adopted son into a gory weapon of his own vigilantism. Not that it's cut-and-dried.]]
* In ''Series/TheITCrowd'', "the first rule of ''Street Countdown''... [[SubvertedTrope is that you really must try and tell as many people as possible about it]]. It's a rather fun game and the more people you tell about it the better."
* ''Series/ThunderInParadise'': Spence & Bru [[RunningGag continuously]] quote different "rule[s] #2" at each other, but never get around to mentioning Rule #1.
* ''TheSlammer'': According to Mr Burgess there are two rules to Dance Club. Rule number 1: You must dance! And rule number two: No fizzy drinks near the stage!
* ''TheGirlsGuideToDepravity'' is all about a set of rules for women in dating and sexual situations. Even the women who are following them know they're fairly dangerous.
