[[folder:J]]
* JackassGenie: {{Discussed}} by Doofenshmirtz in "The Lake Nose Monster" during his rant to Perry.
-->'''Doofenshmirtz:''' Speaking of wishes, you know what I never understood? Genies. They tell you to wish for aaaaanything you want, and then they add some terrible twist. Like, you wish to jump high, so he turns you into a frog. Why? Who gains from this? The genie? I... where's the benefit? You should be fighting genies, man, not me. I'm not the problem: genies. Genies are the problem.
** In another episode he reandomly comments that you should never try to sue a genie.
* JerkWithAHeartOfGold: Candace, while not a jerk per se. For all her obsession with busting her brothers, she does care about them, she's just [[GenkiGirl too impulsive to stop and realize it]].
** Doofenshmirtz is one, especially in the episode "Finding Mary [=McGuffin=]" when he told Vanessa that he's spent about a decade searching for the Mary [=McGuffin=] doll she wanted as a kid. He may be obsessed with taking over the Tri-State Area, but it doesn't mean he's not a dedicated father.
** Buford, definitely. Everyone refers to him as a "bully", though it's probably more accurate to say he's just a friend who threatens you a lot.
* JerkWithAHeartOfJerk: Khaka Pe Pe's motive is revealed to be sympathetic: he never had a best day ever. So Phineas and Ferb stop being the Beak and invite him to join in on their best day ever. His response is to insult their idea for the day, stating "that sounds terrible!" He promptly receives his comeuppance, and never does have a best day ever.
** In spite of their JerkWithAHeartOfGold tendencies, Buford and Doofenshmirtz have their moments too.
*** Most notably, in "Meatloaf" Buford accidentally breaks a bouncy castle before any of the little kids can play on it. He convinces Phineas and Ferb to build an even better one and he brings it to the kids, just to pop it before they can use it.
* JokerImmunity: Doof. {{Lampshaded}} by Vanessa in "Dude, We're Getting The Band Back Together":
-->'''Vanessa:''' He'll be fine. He blows up all the time.
* JourneyToTheCenterOfTheMind: "Monster of the Id" is all about this. Guess whose mind it is? [[spoiler: [[CloudCuckooLander Candace]]'s]]
* JuryDuty: In "Norm Unleashed", Doofenshmirtz was called to be a juror. He expected to be let out of it by admitting he's an Evil Scientist ([[InsistentTerminology "Evil"]], not [[MadScientist "Mad"]]) but the judge decided having one as a juror would be useful as the defendant was another one. Dr. Diminutive was to be put on trial for the damages he caused by using the Schmaltz-inator he "borrowed" (read: stole) from Doofenshmirtz. Doof, despite wanting out of jury duty, denied being acquainted to Diminutive. Both of them started arguing and ended up in prison.
** In that same episode, another juror, when asked to state his occupation, claimed to be "between jobs". Doof thought he said that to get out of jury duty and that it wouldn't work. He ''did'' get out of it but he ironically ''wanted'' to be a juror so he could add that to his resume.
** In another episode, Major Monogram got jury duty. When he was about to state the verdict, he was hit by an inator that makes people say double negatives, causing the defendant to be declared "not not guilty" instead of "not guilty".
* JustTakeThePoster: Discussed in the first episode:
-->"You think we get a discount if we bring the poster?"\\
"Maybe we better take it!" *rip*
** In the episode's musical version, they stated it didn't work last time
[[/folder]]

[[folder:K]]
* KarmaHoudini: In one episode, Doofenshmirtz's EvilPlan is foiled but he doesn't pay for it, which he proceeds to {{lampshade}}.
-->'''Doofenshmirtz:''' Well, that's done. And I got no comeuppance! ... Why do I feel so ''empty?''
** Phineas and Ferb, OnceAnEpisode. But only from Candace's point of view. Ironically, it's shown in the event they're caught for their actions, bad things end up happening, such as Perry the Platypus failing his first mission.
*** And Candace, from the point of view of anyone who doesn't know she's telling the truth (she never seems to get punished for what her parents might view as lying about her brothers... probably because the audience knows she ''isn't'' lying and Disney doesn't want impressionable young kids to know that NoGoodDeedGoesUnpunished).
** Mittington Random, who tried to unravel Klimpaloon and had several deformed clones held hostage, gets no comeuppance other than losing his career and [[MakesSenseInContext being turned into a warthog]].
** Liam the platypus hunter is ultimately defeated, but he receives no authoritative punishment other than being banned from the Danville Botanical Gardens for ten days, which is getting off very lightly considering that he had tried to ''kill'' Perry and Doofenshmirtz.
** The best and special mention goes to Doofenshmirtz's [[AbusiveParents parents]].
* {{Keet}}: '''Phineas Flynn'''
* KickTheDog: Vanessa at the end of "Finding Mary [=McGuffin=]" winds up making a little girl cry. Her father [[DaddysLittleVillain is proud]]. To be fair, though, her father ''had'' spent years upon years searching for the doll just to prove his affection for her.
** While Mayor Roger Doofensmirtz is indirectly responsible for a lot of Heinz's misery, he seems to be a pretty nice guy. Then, when faced with a situation he can't handle, he lets Doof have the office for one day just so he can be a fall guy.
* {{Kidanova}}: For a ButtMonkey, Baljeet seems to have a lot of success with girls his age. He went on a romantic cruise with his childhood friend Mishti, actually kissed a female friend named Wendy, was hit on by several girls [[MakesSenseInContext while he was dressed as a fish]], and managed to unwittingly become the crush of Fireside Girl Ginger.
** Ferb apparently thinks he is one, though we've yet to see him have as much success.
*** In "Vanessassary Roughness," however... (It was just a kiss on the cheek, but not many kids his age could get ''any'' attention from a hot 16-year old.)
**** Also, an adult woman flirts with him in "Run Away Runway."
* KilledMidSentence: In "Gaming the System" (Though it was [[spoiler: a DisneyDeath, as Phineas and Ferb still had four lives left.]]):
-->'''Phineas''': Alright, Candace! Way to-
* KillerRabbit: Perry, Meap, the dodo, and the zoo platypus (though unintentionally on the part of the last).
** Plus a literal one with Dennis the Rabbit.
* KnightOfCerebus: The DrillSergeantNasty from "Phineas and Ferb Get Busted". He's pretty similar to [[Disney/{{Pinocchio}} the Coachman]], another Disney villain, though [[spoiler:he doesn't actually exist.]]
* KnightTemplar: Candace seems to feel this way about her "busting" tendencies.
[[/folder]]

[[folder:L]]
* LampshadeHanging: [[LampshadeHanging/PhineasAndFerb Deserves its own page.]] Arguably, the plot of 7/8 (or more) of the episodes consist entirely of {{Running Gag}}s; therefore, they must be lampshaded in every single possible way. Not to mention the fact that the above listed {{Catchphrase}}s are constantly lampshaded, and that there are two episodes (or one, if you consider that they were 15-minute segments) dedicated almost entirely to hanging lampshades.
* LandmarkingTheHiddenBase: In "Candace Loses Her Head", Doofenshmirtz has a base in Mt. Rushmore.
* LargeHam: Dr. Doofenshmirtz has a nefarious plan to spread this trope across the '''''entire Tri-State Area!'''''
** Candace counts for this, mostly for overreacting dramatically to everything.
** Khaka Pu Pu should count as well, thank you very much.
** As well as the one-time villain, The Regurgitator, seeing as how he has a tendency to talk in a '''loud, booming voice accompanied by dramatic thunder'''.
-->'''Regurgitator:''' (holding out a coffee pot to Doofenshmirtz) You can start by making me a '''''fresh pot of coffee!!''''' (cue dramatic thunder).
* LaserGuidedAmnesia: The entire purpose of the "Forget-About-It-Inator", which works on Linda several times in the space of a few minutes.
* LaserGuidedKarma: Candace and Doofenshmirtz.
** No one in the series is immune from this. Phineas and Ferb are doing fine running on top of giant ball of gumballs until they decide to show off. Suzy gets away with dumping on Candace all she likes, but gets slapped down when she tries to directly interfere with her brother's warm and fuzzy moment.
* LaughablyEvil: Doofenshmirtz, to the highest possible degree. Yes, he wants to take over the entire Tri-State area, and has created everything from Killer Robots and mind-control helmets... [[IneffectualSympatheticVillain but he's so bad at it, it's hilarious]]!
* LaughTrack: There was one in the "Cliptastic Countdown".
* LavaSurfing: Perry catches some lava waves in the episode "Swiss Family Phineas". And of course by "lava", we mean pink soapy water taken UpToEleven.
** Actually, I think you mean BIG LAUNDRY.
* LeaningOnTheFourthWall: "If we were cartoons, we could have all the superpowers we wanted!"
* LeeroyJenkins: Buford, twice, in "The Klimpaloon Ultimatum".
* LeftTheBackgroundMusicOn: Happens fairly often.
* LeastRhymableWord: In the episode "Does This Duckbill Make Me Look Fat?", Doofenshmirtz tries to write his own evil jingle to replace a fast food EarWorm, but can't come up with any good rhymes for "evil."
** Subverted at the end of the movie, where 2nd Dimension!Doof manages to use two during the course of the song.
** In the second Cliptastic Countdown, he tries to rhyme silver. When pointed out that nothing rhymes with silver, he replaces it with orange.
* {{Leitmotif}}: Almost every character has their own theme. Phineas and Ferb build things to an upbeat little ditty (called "Quirky Worky Song"), Perry of course has spy jingles play at certain places, Candace has a tune akin to the [[Film/TheWizardOfOz Wicked Witch's]] theme play whenever she gets suspicious of her brothers, and Doof has an Acapella group open whatever scene he's in. They tinker around with this almost as much as they do {{running gag}}s and {{catchphrase}}s.
** There's one for the line 'I know what we're gonna do today!', which is even used when Doofenshmirtz says it. There's also one for Isabella's entrance and 'What'cha doooin'?', but it's almost exclusive to her. (Or she wishes it was.)
** If you listen closely, Phineas' theme is almost the same as Perry's. The difference is that the boys have a scat, instrumental version while Perry has a spy version with lyrics.
** The Fireside Girls have their own theme, although it isn't heard often.
* LethalChef: Inverted in "Moon Farm", where despite getting the recipe wrong and including things like a blender and self righteous flower, and cooking it at [[OvenLogic 9000 degrees,]] it turns into perfect lamb cobbler. Despite the fact that they didn't put any lamb in it to begin with.
* LetUsNeverSpeakOfThisAgain: Buford and Baljeet agree on this after their clothes get mostly blown off by Ferb test-driving Meap's repaired spaceship.
* LetsGetDangerous: While Isabella is normally pretty competent, anytime Phineas looks to be in real danger, she becomes even more so.
** Candace also falls into this [[BigSisterInstinct if her brothers are ever in danger]], or when she's on a more serious busting attempt.
* LikeASonToMe: Doofenshmirtz's father and his dog, Only Son.
** Norm wishes for this reaction from Doofenshmirtz after the doctor is hit with LaserGuidedAmnesia from his "Forget-About-It-Inator."
* LittleBoySeeksBigGirl: Ferb, who's age is estimated to be [[VagueAge about eleven]], has a crush on Vanessa, who is sixteen. WordOfGod says that they will eventually go out in the future, when the age difference isn't as glaring.
* LimitedSocialCircle: {{Lampshaded}} with prejudice - Candace has only four people on her cell phone phonebook.
* LimitedWardrobe: Commonplace for such shows, but {{lampshaded}} by Candace:
-->'''Candace:''' I am gonna wear my cute white skirt with my favorite red blouse, white shoes and matching red socks! Whaddaya think?
** Ironic, considering the fact that she and, to a lesser extent, Stacy, seem to be the ones who most regularly get wardrobe changes, and probably the only ones who get wardrobe changes that aren't just silly.
** Later {{Lampshaded}} again by Phineas and Ferb, when their mom has them go shopping for school clothes and it takes them less than five seconds. "Well, we ''do'' have a signature look."
** Coltrane ''would'' have one, if the animators would just decide what outfit he would stay in.
* LipstickMark: Parodied by Doofenshmirtz having a pawprint on his cheek from a new nemesis he was trying to conceal from Perry.
** Played straight in another episode. "Oh, there you are, Perry. Why ya all covered in lipstick?"
* LiteralGenie: The Supercomputer in "Ask a Foolish Question"
* LiteralMinded: ''Everyone'' whenever it suits the RuleOfFunny. For example, Linda is confused to see that a band called "Tiny Cowboy" consists of two tall guys who clearly aren't cowboys.
* LiteralSplitPersonality: Happens to Candace and Major Monogram when they accidentally get hit with Phineas and Ferb's molecular splitter.
* LongList: "Mom's Birthday" has a scene with an increasingly-frantic Candace going through a list of instruments with the letter "b" as they're shrunk into nothingness by Doofenshmirtz's latest invention.
* LoonyFan: Irving, especially in the episode "Hide and Seek". Phineas and Ferb are slightly creeped out by him (understandably) - most likely an AffectionateParody of the show's own fanbase.
** He's since become a recurring character who winds up being the SixthRanger of Phineas and Ferb's group.
* LoopholeAbuse: Phineas and Ferb are kids, and thus don't have driver's licenses and aren't allowed to drive. Thus, they simply drive vehicles via remote controls.
** In episode "Agent Doof", Doofenshmirtz decided to become an agent of O.W.C.A. Because of the time he was raised by ocelots, he technically meets the basic requirement for the job (being an animal).
** Candace and Linda once signed an agreement regarding Candace busting her brothers. One of the terms was that Candace couldn't try to bust them more than once per day. [[WhenTheClockStrikesTwelve Cue to midnight]], and Linda was considering adding a new clause to their agreement.
** In "Perry the Actorpus", Major Monogram sends Sergei the Snail to stop Doofenshmirtz, who neutralized Sergei by surrounding him with salt. When Perry showed up, Doof invoked a rule from the O.W.C.A. bylaws that prohibits any agents from beating up villains another agent was assigned to stop unless the other agent is incapacitated and pointing out that, despite being surrounded by salt, Sergei the Snail technically isn't incapacitated. Perry solved the problem by removing the salt while Doof was distracted reading the rule.
* LovelyAssistant: Parodied in "Let's Take a Quiz!" While Phineas plays game show host, the role of the Lovely Assistant is taken by Ferb, who appears in several glamorous women's outfits.
* LoveMakesYouDumb: In the episode where Candace is split in two, the Candace that is obsessed with Jeremy is a total flake.
* LowerDeckEpisode: "Bubble Boys"/"Isabella and the Temple of Sap".
** And technically "Unfair Science Fair" and "Unfair Science Fair Redux (A Different Story)", though the latter takes place a day or so before the main chunk of the former.
** "Not Phineas and Ferb" centers around Irving trying to convince his brother that Baljeet and Buford are Phineas and Ferb. The only things Phineas and Ferb do in the episode are watch a movie and show up in the backyard just in time to make Candace look insane.
** "Delivery of Destiny" shows a day in the life of a delivery truck driver named Paul who gets caught up in the wacky hijinks of both Phineas and Ferb and Perry the Platypus.
** "Bee Day"/"Bee Story".
* LukeIAmYourFather: Parodied, but averted in "The Chronicles of Meap".
-->'''Mitch:''' Just so we're clear, I am '''not''' your father.
** [[IncrediblyLamePun Son of a Mitch!]] Get it?
* LyricalDissonance: In "Meapless In Seattle", we have a [[TastesLikeDiabetes super-cutesy]] song about the Meap army...going to war and destroying their enemies.
** "Norm Unleashed" has "Weaponry", where Norm sings a jaunty, cheerful tune about arming himself with various weapons and laying waste to Danville.
[[/folder]]

[[folder:M]]
* MacGuffin: The Pizzazium Infinionite in "Vanessassary Roughness". One episode involving Candace losing her favorite childhood doll, who is appropriately named Mary ''[=McGuffin=]''...
* MacGyvering: Inevitable when the main characters are a pair of {{Gadgeteer Genius}}es, most notably at the climax of "Summer Belongs to You!" when they create a giant slingshot-powered airplane using a map and a rubber band.
** Averted most of the time, however, as they typically order the parts they need.
* MadeOfExplodium: In "Ask a Foolish Question", Doofenshmirtz lampshades this by, after a series of violent explosions, saying "Why does everything explode so easily?" followed by another explosion.
** "Road Trip" has Doofenshmirtz driving a truck full of "Boom Juice".
* MadeOfIron: Major Monogram has stated that he is 35% metal in "Summer Belongs to You". Everyone probably fits the normal manner of this trope, but it's most obvious with [[HoistByHisOwnPetard Doofenshmirtz]] and [[SlapstickKnowsNoGender Candace]].
* MadLove: Norm has this for Doofenshmirtz in a WellDoneSonGuy sort of way. Doof has ''no'' parental affection for him, but it doesn't stop Norm from trying.
* MadScientist: Dr. Doofenshmirtz, as usual.
** When Phineas and Ferb create a helmet that increases his intelligence, Baljeet temporarily becomes one and makes a plan to transfer the Earth's atmosphere to the Moon.
* MadScientistsBeautifulDaughter: Vanessa Doofenshmirtz. Played with in that instead of betraying her father for good, she more-or-less tries to ignore the moral battle she has to deal with every other weekend.
* MagicianDetective: Dr. Doofenshmirtz imagined Agent P as one of these in the ShowWithinAShow "Doof 'n' Puss".
* MagicCarpet: "[[ExactlyWhatItSaysOnTheTin Magic Carpet Ride]]".
* MagicSkirt: Candace and the Fireside Girls, in numerous episodes.
** In "Leave to Busting to Us!" Candace and Isabella's skirts defy both gravity and inertia in order to always cover their panties during the waterslide sequences.
** "The Paper Pelican Floor Show", a musical number in the episode "De Plane! De Plane!" has Isabella completely upside down at one point, but her skirt acts like it's made of fiberglass. Candace's skirt does the same trick when she's on the monkey bars in "Journey to the Center of Candace".
** Even when Isabella's in a zero-gravity environment, her skirt does not behave as such.
** In one episode the Fireside Girls are on a rollercoaster track with a high gust wind. Mother Nature made sure she didn't flip their skirts all the way up.
** In "The Ballad of Badbeard" an eagle is carrying Candace by the edge of her skirt in shots of her front, but in shots of her rear it switches so the talons are gripping the middle of her skirt. So her panties are invisible from all angles, even if it creates a continuity error.
** In "Hawaiian Vacation" Candace falls down a water fall feet first, her hair flies up but not her dress.
** "Backyard Aquarium" is even more blatant, as she gets thrown around by huge sea creatures and her skirt never flies up despite falling feet first.
** "Run Candace Run" brings this up to new heights. She's running so fast that her skirt constantly flips and flops around, but it stays glued to her crotch area.
** In "Let's Bounce", Linda implies that Candace is wearing a skort.
* MagicVersusScience / TheMagicVersusTechnologyWar: Well, sci-fi verus fantasy in "Nerds of a Feather".
* MajorGeneralSong: I am the very model of a modern Major Monogram / I've information vegetable and animal and hologram.
* ManateeGag: Given that most of the songs are there only for the OnceAnEpisode flavor, their lyrics sometimes devolve into WordSaladLyrics involving some pretty bizarre stunts, most of which get animated anyway. {{Lampshaded}} in "The Secret of Success" when an actual Manatee hangs out with them for portions of the song, leaving the boys with a rather uncomfortable look on their faces.
** Played straight in "Chez Platypus" and "Rollercoaster".
* ManChild: Doofenshmirtz. He's physically in his 40s, but mentally around 8.
** Major Monogram has shades of this, [[CharacterizationMarchesOn especially in later seasons]], though he can be serious when he has to.
* ManipulativeBitch: Suzy.
* ManlyTears: In the episode "Oh, There You Are Perry", Perry discovers that he is being transferred to another villain and, therefore, will never see his family again. Back at the house, Phineas is inside, scared that his pet is missing and stating that he would be devastated if anything happened to him. Cut to Perry, watching from the window, [[TearJerker stopping by to get one last look at them]]. And you can tell he's on the verge of tears.
* MasculineLinesFeminineCurves: Phineas is blocky with a triangular head; [[MadScientist Doofenshmirtz]] is the the same but his edges are rounded off. Ferb, [[BumblingDad Lawrence]] and [[MissionControl Major Monogram]] are made of a series of boxes. Candace is quite angular but has a round face; Isabella and the Fireside Girls are similar. Linda and [[MadScientistsBeautifulDaughter Vanessa]] are all curves.
* MassiveNumberedSiblings: Lawrence Fletcher's brother Adrian has six children. [[MeaningfulName Three boys named Beckham]]; two boys named {{Pele}}; and one girl named Eliza [[DavidBeckham Beckham]] Fletcher. Just shows how much Adrian loves TheBeautifulGame.
* {{Masquerade}}: Perry must keep his secret agent identity concealed from the Flynn-Fletcher family to avoid being relocated by the OWCA. He acts like a mindless domestic animal around them and only dons his fedora in private. The reason for this is that the information of who Perry is could potentially put not only Perry, but Phineas and Ferb in danger. Or it could just lead to a lot of empty doorsteps when the family heard the doorbell, as Doofenshmirtz said (in the episode Hide and Seek) doorbell ditching was a reason he wanted to find out where Perry lived.
** Maintained only by incredible luck; The boys appear to their mother to be regular kids, with no ability to do anything extraordinary.
* MathematiciansAnswer: A meta example. A fan asked Dan Povenmire "What is Ferb short for?" He [[https://twitter.com/DanPovenmire/status/398613075290378240 answered]], "Brevity's sake."
* MayContainEvil: Baljeet's curry-flavored gelatin is suspected to be the cause of the gelatin monster.
-->"It is not ''inherently'' evil. Maybe a little spicy."
* MayDecemberRomance: The age difference between Ferb and Vanessa doesn't stop people from {{shipping}} them.
** Of course, this may be because Dan Povenmire thinks that they'll get together when they're older and the age difference is less important.
** Baljeet's parents must be a case of this. Baljeet's father is already a mustached adult by 1957 according to "Tour de Ferb", indicating that he's probably 70. Since Baljeet's mother looks like she's as old as Linda...
** ... not to mention that she's in her late 30s and Lawrence is most likely in his mid-to-late 50s (having worked as a researcher in Africa from 1976-1989).
* MeaningfulName: The name "Doofenshmirtz" can be rather [[BilingualBonus amusing to viewers with German knowledge]] because it loosely translates to "stupid pain" in German.
** Made more amusing in the original pitch; originally his name was 'Meddleshmirtz' but pronounced [[http://www.urbandictionary.com/define.php?term=mittleschmertz 'Mittleshmertz']] (for those who don't feel like reading the full definition, 'Mittleshmertz' is a term for a pain that occurs prior to ovulation)
** Many of the historical figures as well.
** Phineas is an energetic boy who tries to make summer as fun as possible while making expert use of RefugeInAudacity. Sounds a lot like [[Literature/ASeparatePeace another boy named Phineas]]. However, WordOfGod claims that he was named after [[AroundTheWorldInEightyDays Phi]](n)[[AroundTheWorldInEightyDays leas Fogg]].
* {{Meganekko}}: Gretchen and Charlene Doofenshmirtz.
* MeritBadgesForEverything: The Fireside Girls have patches for just about everything, including those that shouldn't be undertaken by nor rewarded to little girls. Like "Wrestling an Alligator In A Sewer Patch" or "Reckless Disregard for Life and Limb Patch"[[note]]though Isabella may have been joking about that one[[/note]]. Naturally, the patch they're working on usually jibes with whatever they need to do to help with the P&F's scheme-of-the-day.
** Subverted. There's no patch for Persistence, and there's also no Underwater Equestrian patch, because seahorses are too small to ride.
-->"Not if you scoop a big bunch of them and ride it!" [[spoiler:It works.]]
** There's also no patch for Help Phineas and Ferb. Adyson shouldn't make up patch names like that.
* MessyHair: Both the titular characters have rather unkempt hair.
** Isabella's hair gets messy in one episode to the point of it [[http://www.youtube.com/watch?v=suy0cjbFTgY having its own song]].
* MetaGuy: Dr. Doofenshmirtz has become more and more aware of the FourthWall as the series has gone along. Usually he does this by poking fun at his own [[ExpansionPackPast increasingly complex and nonsensical backstory]], but he also told a chorus girl to wait to leave until the show faded to black in "Rollercoaster: The Musical", and complains when Perry disrupts the usual order of their story.
* {{Metaphorgotten}}: As the band Love [[HeavyMetalUmlaut Hndel]] broke up due to infighting:
-->"Lines were drawn. Then lines were crossed. Eventually, the lines were erased and the piece of paper was crumpled up and thrown away."
** Phineas's narration in "Finding Mary [=McGuffin=]" goes a little farther than necessary:
-->'''Phineas:''' The sun beat down on the city like a hammer; a relentless, hot, beating hammer hammering down like a big metaphor that was... hot, for some reason.
* MindControlMusic: The point of Doofenshmirtz's "My Name is Doof" song in the cliptastic countdown.
** Doof also tries this with country/western with the song "Yodel Yodel Yodel Yobey me!"
** The alien criminals in "Mind Share" seem to go into a very suggestive state when exposed to music.
* MindScrew: The ending of "Mommy Can You Hear Me?". Then again, it ''was'' referencing [[Film/TwoThousandOneASpaceOdyssey one of the mind-screwy-est films in history]].
** The ending of "The Curse of Candace".
** Pretty much the entity of "Monster from the Id", which makes sense since it's a JourneyToTheCenterOfTheMind of a CloudCuckooLander, but special mention goes to the scene near the end when they escape the Id.
** A scene during the song sequence of "No More Bunny Business". When Isabella puts on the x-ray glasses, she sees Phineas and Ferb dancing...until they switch skulls. However, she takes the glasses off to find the boys back to normal. [[http://www.youtube.com/watch?v=TRYskwACMUY Now for a clip.]]
** The ending of "Tri-State Treasure: Boot of Secrets" leaves you wondering how much of it was a movie and how much really happened.
** The final circus act in "Jerk De Soleil".
* MindScrewdriver: "Remains of the Platypus" starts in the ''middle'' of the episode's plot, then gradually reveals the earlier events that led up to the opening scene.
* MiniDressOfPower: The Fireside Girls.
* MinoredInAssKicking: Ferb is normally [[TheStoic extremely quiet, reserved and peaceful]], but in the episode "Raging Bully", he took out Buford, the bully, in ''one'' [[Franchise/StarTrek Vulcan-esque]] nerve pinch.
-->'''Ferb:''' Well, he was all up in my face.\\
'''Buford:''' Ugh, what happened?
* MirrorMoralityMachine: The Turn-Everything-Evil-inator and the Misbehave-inator, which also turns Buford temporarily nicer.
* MisplacedWildlife: The title sequence shows the boys discovering a dodo bird on a mountaintop. Dodos lived exclusively in the undergrowth of tropical deciduous forests, and would be ill-suited to an alpine environment. In the actual episode where this happens, it is justified because the dodo was artificially hatched by Doofenshmirtz.
** The episode "Greece Lightning" claims that vipers and badgers are the natural predators of platypi. Platypi are exclusive to Australia, which had neither badgers nor vipers until the latter were accidentally introduced in recent times.
** Steve the North American chameleon. Though the New World [[http://en.wikipedia.org/wiki/Anolis anole lizards]] are sometimes called "chameleons" and have some color-changing ability, true chameleons (which Steve is clearly based on) are known only from the Old World (mostly Madagascar).
** This is a plot point in "Tri-State Treasure: Boot of Secrets". When Lawrence is deciding from a collection of boot scrapers which one is the genuine artifact he is after, his rival barges in and snatches a hedgehog-shaped boot scraper. Lawrence points out that the boot scraper can't be the right one, as there are no hedgehogs in America, and indeed a booby trap is triggered moments afterward.
** "Where's Perry?" shows lemurs on mainland Africa.
** An apparently wild yellow-billed oxpecker (from Africa) in Danville shows up in "What'd I Miss?"
** A tiger is shown in Danville in "Tour De Ferb", though it is implied that it escaped from captivity.
** The numerous platypuses in "Oh, There You Are, Perry" might count, as it is hinted in the same episode that platypuses are not common pets even InUniverse.
** Grandpa Fletcher [[TallTale claims]] he once fought wild tigers in the Amazon.
* MissionControl: Major Monogram. Isabella and the Fireside Girls in "Out to Launch". (In the usual "ground control for space mission" way.)
* MistakenForAliens: In "[[TheJoyOfX Invasion of the Ferb Snatchers]]", a series of unlikely coincidences convinces Candace that Ferb is an alien. [[spoiler:He wasn't, though he and Phineas ''were'' fixing a spaceship for one.]]
** Both Phineas and Ferb are mistaken for aliens in "Sci-Fi Pie Fly". [[spoiler:They meet real aliens that actually do resemble them later in the episode.]]
* MistakenForAnImposter: "Not Phineas and Ferb" plays it straight, attempted unmasking and all. "Get That Bigfoot Outta My Face" is a subversion because [[spoiler:it's a more elaborate imposture and Candace is in on the joke]].
* MistakenForSubculture: Candance and Vanessa end up wearing each other's clothes after their dry cleaning is switched. Candace is mistaken for being a Goth, and Vanessa is mistaken for being a clown by her father.
* MisterExposition: Major Monogram.
* MisterSeahorse: Referenced, as a joke, in "Oh, There You are Perry!"
--> ''I am not here to apply for an internshi-...Ooh, you offer maternity leave!''
* MobySchtick
* ModestyTowel: Candace spends almost the entirety of "Gaming the System" in one, despite running, jumping, and fighting her way through a video game.
** Also Candace and Stacy in "Spa Day".
** And now Linda in "Tour de Ferb". What's with this trend?
* MoodMotif: Several.
** Candace being frantic to bust the boys.
** The A Capella Choir of Whimsy sings when the boys are industriously building something.
** Doofenshmirtz's theme is also an A Capella Choir of Whimsy, and so is Perry the Platypus' theme.
* {{Montages}}: Generally OnceAnEpisode.
* MoodWhiplash: Immediately after the cutest VillainSong ever written, "Evil Love", Doofenshmirtz's date [[spoiler:gets her love removed and indifferently leaves him heartbroken]].
** In the middle of the [[CrowningMomentOfHeartwarming heartwarming]] / [[TearJerker tear jerking]] song "Come Home Perry", we have Candace "[[CrowningMomentOfFunny running out of rhymes]]". It doesn't really detract that much from the original spirit of the song, however.
* {{Mondegreen}}: In "Imperfect Storm", Candace tells Candace that "Du Bois" have messed up her yard. She believes that she is referring to "the boys", AKA Phineas and Ferb, and begins to sing how she has finally won.
* MoralGuardians: Given quite the TakeThat in "Phineas and Ferb's Quantum Boogaloo". They basically ''destroy society''.
* MoralityPet: Vanessa to Doofenshmirtz, but of course, he's not exactly a nasty guy as it is.
* MorallyAmbiguousDoctorate: Dr. Doofenshmirtz admitted to obtaining his degree over the internet with his ex-wife's money. He also has a scheme involving offering these in the [[FunWithAcronyms Doofenshmirtz Institute of Evilology]], and apparently took Evil 101, but he never got a diploma. There seems to be a lot of support for the evilological field in this universe.
* MostAnnoyingSound: {{Invoked}} with Alien!Baljeet's squeaking head in "Mind Share". [[invoked]]
* MostWritersAreAdults: There are some jokes and {{shout out}}s that would be hilarious to ''[[ParentalBonus anyone]]'' but the target audience. There's a ''Film/TwoThousandOneASpaceOdyssey'' parody, for crying out loud.
-->'''Doofenshmirtz:''' I know, weird, right? They go all Kubricky on it.
* MotorMouth: It may just be because his brother is almost totally silent, but Phineas comes off as this fairly often.
* TheMovie: [[PhineasAndFerbTheMovieAcrossThe2ndDimension Phineas and Ferb: The Movie: Across the Second Dimension]]. One in which Phineas and Ferb ''find out about Perry being a secret agent.'' Yes!
** There were plans for a theatrically released movie at one point.
* MultipleChoicePast: Doofenshmirtz.
** "It all started on the day of my actual birth. Neither of my parents showed up." He had to pretend to be a lawn gnome after theirs was repossessed, he had to wear dresses, he wasn't allowed to go swimming in public pools, his father preferred the dog and named it "Only Son" and he was abandoned and raised by ocelots.
*** Of course, for Doofenshmirtz, the correct answer is always E: All of the above.
**** [[TheSpoonyExperiment There is no continuity, there is only Doofenshmirtz]].
* MultipleDemographicAppeal: For a DisneyChannel cartoon, it sure pulls in more than its target demographic.
* MundaneMadeAwesome:
** A CrowdSong, and indeed entire episode, about ''[[WhatTheHeckIsAnAglet aglets]]'', and that's just the [[IncrediblyLamePun tip]] of the iceberg.
** One whole episode was spent playing on those kiddie rides by stores you can ride for a quarter. Much more awesome than it sounds.
** In "Candace Gets Busted", the party-goers get overexcited watching Phineas and Ferb just sit on the couch eating potato chips.
** "Make Play" begins with Lawrence describing a jukebox. He greatly over-romanticizes it a tad.
** Meatloaf. Not only was Linda crowned the 'Meatloaf Queen', but, apparently, Danville has an annual meatloaf festival (with meatloaf themed rides, a bounce house and [[ShoutOut 32]] varieties of [[BreadEggsMilkSquick meatloaf flavored ice cream]].) Candace brushes it off as stupid until her favorite band starts singing about how they love the stuff.
** Carl driving an ice cream truck to distract Buford and Baljeet (so that Perry can leave for his mission).
** The entirety of Carl's theme song.
** Perry's Hat. It's ExactlyWhatItSaysOnTheTin: An entire song about Perry's trademark fedora and ''its airborne journey through Danville''.
** Boot scrapers.
** Some of the ways Perry defeats Doofenshmirtz can fall into this, especially when accompanied by his theme song. In "Hide and Seek" all he needs to do is crush a small robotic eye between his fingers to foil Doofenshmirtz's plan.
** Everything [[LargeHam The Regurgitator]] says is accentuated by his lightning effects, even lines like "You can start by getting me a fresh pot of coffee!"
* MundaneUtility: In the Science Fair episode, a girl shows up with a set of [[SpiderMan Doctor Octopus-esque]] set of [[MultiArmedAndDangerous mechanical arms]]... which she used to build her real entry, a baking soda volcano.
* MurderTheHypotenuse: Parodied in "Suddenly Suzy" when Candace hides anything that could potentially be used as a murder weapon before Suzy arrives.
* MusicalEpisode: Pretty much every episode has a song or two, though occasionally there will be full-on musical episodes. These include "Dude, We're Getting the Band Back Together!", "{{The Wizard Of O|z}}dd", the double-length "Summer Belongs to You!", and the [[ExactlyWhatItSaysOnTheTin appropriately titled]] "Rollercoaster: TheMusical!"
** The beginning of Rollercoaster: The Musical {{lampshade| hanging}}s this at the beginning.
-->'''Phineas:''' We should do the whole thing again, but this time, we'll break into spontaneous song and choreography with [[InvisibleBackupBand no discernible music source]].
* MusicalWorldHypotheses: The characters do definitely live in a musical world, although an...interesting one. While people do burst into song and dance at random times, Doofensmirtz has been known to hire back-up singers specifically for this purpose. Also, the MusicalEpisode lampshades it to hell and back.
-->'''Phineas''': Why don't we burst into spontaneous singing and dancing with no discernible music source?
** Also, they appear to be able to hear the soundtrack- and their singers. They have, in fact, had arguments with them
** City Hall has a diorama room dedicated to Danville's spontaneous musical numbers in "WHere's Pinky." You can even [[{{Callback}} spot a couple]] like "I got Rhythm.
* MustacheVandalism: In the title sequence, the boys draw a mustache on what looks like a painting of Candace, until she pops her head out of the picture frame to yell, "Phineas!" Kind of odd, since vandalism really isn't the boys' style (currently provides the page image).
** An episode had Perry use the mustache-inator to deface all the posters and billboards of him.
* MyFriendsAndZoidberg: "Friends... Bullies... Irving."
** Ferb also addressed Isabella as this during his speech in "The Lizard Whisperer".
-->'''Ferb:''' And [[Creator/WilliamShakespeare we few. We happy few]]. (To Phineas) [[NotBloodSiblings We small band of brothers]] -- (To Isabella) [[GirlNextDoor and girl from across the street]].
* MyFutureSelfAndMe: Candace in "Phineas and Ferb's Quantum Boogaloo".
* MyGodWhatHaveIDone: In "Phineas and Ferb Get Busted!", Candace yells this out after her brothers' [[BreakTheCutie personality wipeout]] ended up as the result of her finally managing to expose their experimentations to their mom. [[spoiler:Luckily, this turned out to be a double nightmare Perry was having. Of course, Candace continues her fruitless attempts to bust her brothers, but at least the episode showed that she loves them regardless.]]
** Or at least that [[spoiler:Perry]] thinks she does.
* MySignificanceSenseIsTingling: In "Thaddeus and Thor", when Candace hurriedly stacked cans in the kitchen so her mother could see Phineas and Ferb's latest creation, we cut to Doofensmirtz who says "I just sensed a disturbance in the cup stacking universe. I think my record's been broken".
** Isabella senses Candace using her CatchPhrase in "Phineas and Ferb's Christmas Vacation." While in a different house.
* MyspeldRokband: [[GettingCrapPastTheRadar Love Hndel]].
* MysteryMeat: On the episode where they build a truck stop, Ferb can be seen scooping out ingredients from a large can labeled "assorted mammal chunks."
[[/folder]]

[[folder:N]]
* NameAndName
* NegativeContinuity: In "Ain't No Kiddie Ride", [[TheIntern Carl]] mentions that he was born without nostrils, but in "Brain Drain" he said he was afraid of the smell of garlic and he takes a smell of perfume in "The Curse Of Candace". Also the part of "Curse" where [[spoiler: Candace turns into a vampire, and then dies.]] Other than that, this trope is averted very well.
* {{Nerd}}: More major and minor characters than it is possible to list here, but the two most prominent examples are [[BollywoodNerd Baljeet]] and [[TheIntern Carl]].
* NerdCore: This show writes songs about ''everything'', and "nerdy" subjects are certainly included. There's even a few songs on Baljeet's part about actually ''being'' a nerd.
* NerdsLoveToughSchoolwork: Baljeet, oh so very much. He is ''introduced'' in the show [[EstablishingCharacterMoment reading a big pile of school books...during summer vacation.]]
* NeverMyFault: Doof blames Perry for his plans failing, even when he screws them up himself. In "That Sinking Feeling" he curses Perry when his [[ItMakesSenseInContext lighthouse rocket]] ends up lodged in the Evil, Inc. building even though Perry had completely failed to foil him that time.
** Also, when Doof failed to destroy the adult diaper factory, he blamed Perry despite acknowledging Perry had no role on it whatsoever.
** Dr. Diminutive once "borrowed" (read: stole) Doofenshmirtz's Schmaltz-inator and used it for something he was arrested for. He blamed Doof for his arrest just because it was Doof who invented the inator.
* NeverSayDie: Actually averted by Candace in Gaming the System when she thinks Phineas and Ferb [[SelfDemonstratingArticle went to a better place]].
* NeverLiveItDown: [[{{In-universe}} Invoked]]:
-->'''Baljeet:''' Hey Buford! We are going to be floating like [[CallBack little woodland pixies]]!\\
'''Buford:''' You're never gonna let me live that down, are you?
* NeverTrustATrailer: Many scenes from fake trailer for "Meapless in Seattle" were incorporated when they made actual episode the way that completely alters their meaning.
** For example, the scene with Major Monogram ordering Perry to turn over his hat suggest Agent P would be fired but it was revealed it was just to upgrade the hat. The scene with Perry throwing a chair at Monogram's screen was revealed to be a way to test the screen's unbreakable aspect. It passed and Monogram ordered an unbreakable ''chair''.
** The trailer scene featuring [[spoiler:Suzy]] for "Meapless in Seattle" became [[spoiler:a trailer for the prequel. Doofenshmirtz even called everyone's attention to this.]]
* NewMediaAreEvil:
-->'''Monogram:''' You know, that building across town with the giant vacuum cleaner on top? Man, I can't believe that place closed. I blame the internet.
* NiceGuy: Phineas. ''Seriously.'' He has gotten truly angry perhaps ''twice''[[note]]Not counting "Phineas and Ferb and the Temple of Juatchadoon", as that was an alternate version of him[[/note]] so far in the ''entire'' series and managed to recover fairly quickly on both occasions. He even agreed to help his sister bust him once without batting an eye just because it would make her happy, and that was on the [[HorribleJudgeOfCharacter one occasion]] where he even ''acknowledged'' that she was trying to bust him at all.
** Jeremy as well, [[SingleWomanSeeksGoodMan which is lucky for Candace]].
* NiceHat: Perry. To the point where, without it, nobody recognizes him, although this is more ClarkKenting than anything else.
** This is actually implied to be more Doof holding the IdiotBall, as other characters recognize him immediately, whether they normally see him with his hat on or off. For example: One episode Perry escaped a trap by taking off his hat, causing Doofenshmirtz to release him, believing that he was a normal platypus. When Perry put on his hat again, Doof wondered what he had done with the other platypus.
** At one point, he loses his hat and instinctively reverts to mindless-animal mode, despite being in the company of Doofenshmirtz and Vanessa. He also appears almost incapable of doing anything important before donning his hat (a particularly glaring example is in "Traffic Cam Caper").
* NiceJobBreakingItHero: [[spoiler:Linda]] is the one who gave Doof the idea of taking over the Tri-State Area.
* NightmareFace: [[http://phineasandferb.wikia.com/wiki/File:Creepycandy.PNG ...Everything okay, Candace]]?
* NightmareFuel: [[{{In-universe}} Doofenshmirtz's own personal case]]: He tumbled through an assembly line while being pelted with hundreds of Perry the Platypus look-alikes from "Toy to the World". He spent most of it screaming, and when he got a brief break he remarked how disturbing it was.
** In the commentary for "The Chronicles of Meap", Major Monogram says Meap is this, even using the term "Nightmare Fuel".
* NightmareRetardant: An in-Universe example: In the episode "One Good Scare Ought to Do It", when Baljeet (dressed as a failed math test) and Buford (disguised like Suzy Johnson) try to scare Phineas and Isabella.
* NinjaPirateRobotZombie: [[{{Mooks}} Ninja vampires]] from Heinz's show.
** The good Doctor also cast himself as a "rogue trillionare-inventor-extreme fighting champion FROM THE FUTURE! in "Doof n'Puss".
* ElNinoIsSpanishForTheNino: "As they say in Mexico, 'Dasvidaniya!' Down there, that's ''two'' vidaniyas!"
** Made even better by "Dasvidaniya" actually being Russian for "Goodbye".
* NoBigDeal: To be put simply, 99% of the population of Danville would require an ''extreme'' amount of weirdness to be confused/shocked by something, the only exception being Linda and Candace (Though that's usually only if said weirdness is made by Phineas and Ferb)
** [[InvokedTrope Invoked]] by Phineas in "Gi-Ants"
--> "You know what I like about our friends? We say things like, 'We're gonna douse you in ant pheromones.' And they're just like, 'Okay, whatever'. They're so cool."
* NoEyeInMagic: After Mitch [[spoiler: becomes super-cute]] in "Meapless in Seattle", [[spoiler: Phineas and the Meapian army look at him, falling under his control.]]
* NoFourthWall: Everyone in 'Phineas And Ferb's Musical Cliptastic Countdown' and Phineas in 'Finding Mary McGuffin'.
** In "Make Play":
-->'''Monogram:''' Oh wow, what are the odds?\\
'''Carl:''' Well it is a cartoon, sir.\\
'''Monogram:''' What did I tell you about breaking the fourth wall, Carl?
** One only has to watch the first couple of minutes of "Rollercoaster: The Musical" (not to mention the rest of it) to see that the creators really don't care about the integrity of the fourth wall anymore.
** During the "Moon Farm" episode's [[http://www.youtube.com/watch?v=WxnIoEMhna8 song]], Baljeet gets into an argument with the "[[NinjaPirateZombieRobot Disembodied Reggae Space Voice]]" singing.
** The show edges towards this more and more. Like how characters remark that they have to do things because its in the theme song? Or Ferb saying that it usually takes them "at least a montage" to build things? Doof saying his head hurts to much to go into FlashBack mode? Phineas insulting advertisements for ruining his visual gags?
** The entire episode of "What'd I Miss?" has No Fourth Wall, with characters mentioning the narration and noting that they can't see the flashbacks.
* NoInfantileAmnesia: {{Invoked}} with Dr. Doofenshmirtz, who claims that his parents somehow missed witnessing his birth date, even though logically his mom should be present.
** [[WildMassGuessing Not necessarily.]]
* NoirEpisode: "Finding Mary McGuffin".
* NonActionGuy: Baljeet, normally, though you shouldn't [[HiddenDepths push it]].
* NonIndicativeName: "Wizard of Odd" gives us this gem:
-->'''Phineas:''' ''[After Candace and various others start falling from a plane]'' Wow, dumb luck. And over the Sea of Razor Sharp Rock Spires too!\\
'''The Others:''' AAAAAAAAAAAAAAHHHHHHHH!\\
'''Phineas:''' Good thing it was so inappropriately named!\\
''[Que them falling onto an extremely bouncy mountain of pillows]''
* NoPeripheralVision: One of the main reasons Linda never sees the boy's inventions.
* NonSequiturThud: Stacy: "Uh, it's not my ferret!"\\
'''Major Monogram:''' Wrong pants!\\
'''Doofenshmirtz:''' Hold the door, Barbara, I think this is our floor. Mama, I'm pretty.
* NonStandardCharacterDesign: Vanessa, minorly. She's literally the only high school age character on the show to have a "womanly" kind of body.
** Also, pretty much every time there's a guest star, their InkSuitActor is slightly more realistic than most characters.
* NoodleImplements: "Why don't you grab your peanut butter and your swimsuit and meet me at the flagpole?"
** The outlandish items the parents pack for their trip in "Summer Belongs to You".
*** To be fair, those are just handed by Lawrence to Linda to be packed. If you watch closely, you'll see that she tosses most of them aside or under the bed. The only thing she packs is the T-shirt.
* NoodleIncident: Comes up from time to time. Sometimes played straight (the time Candace got her head stuck in the sink), and, since one of the creators of the show used to work on WesternAnimation/FamilyGuy, there will obviously be some subversions (Dr. Coconut).
** Whatever Linda did to embarrass Candace at her 5th grade graduation "with the inflatable..."
** Doofenshmirtz and his strange obsession with using Eulg (which destroys stickiness) on the Tri-State Adult Diaper Factory. It is, apparently, backstory worthy. Perry the Platypus chose, wisely perhaps, not to find out.
** Whatever happened when the Fireside Girls went to see what Baljeet is doing to earn a patch. It was rather implied that it was a bad decision.
-->'''Holly:''' ''That'' patch wasn't worth it.
** Also from the same episode, whatever happened when Milly went back one afternoon after the other Fireside Girls went home.
** In "We Call It Maze" we hear the beginning of Doof's backstory:
-->'''Doof:''' Ten years ago I was backpacking across Europe when I came across [[NoodleImplements a group of Canadian college students]]. [[TheRival Dylan]] was the most popular among the group, but I was the oldest, so rivalry was inevitable...
** But not the middle, just the end:
-->"...then the ambassador's wife filed a complaint: long story short, [[PersonaNonGrata I am never welcome in Albania ever again]]. But the point is I ended up alone in Italy..."
** Doof's actually full of these:
-->'''Doof:''' (Upon seeing a dodo, expressing his disappointment) "... it looks like a turkey! It's like Thanksgiving! (the dodo starts attacking him and we hear, from off screen) ''Exactly'' like Thanksgiving!"
** From the episode featuring Paul the delivery guy, we get this one from Love Handel:
-->'''Bobbi:''' "Hey guys, we're covered in juice and packing tape. What does that remind you of?"\\
'''Danny:''' Detroit, 1984. *Danny and Swampy high-five.*
** Similarly in the movie, when their bus gets knocked over by killer robots it's "Albuquerque '93 all over again."
** In "Lotsa Latkes" Candace explains why she can't hang out with her friends by saying Jeremy is working, Stacy is grounded and Jenny is protesting. We know where Jeremy works, but there's no explanation for why Stacy is grounded or what Jenny is protesting.
** "Norm Unleashed": Whatever Doofenshmirtz's Schmaltz-inator can be used for, it was something Dr. Diminutive was arrested for when he used the inator.
** The Fireside Girls' first attempt at getting their beekeeping patches.
** The "Clothesline Incident" mentioned in "Knot My Problem."
* NoOntologicalInertia: Due to Dr. Doofenshmirtz and Perry, Phineas and Ferb's inventions always disappear.
* NoOSHACompliance: Apparently, the boys are a [[RunningGag little young]] to know anything about OSHA. Some examples:
** The set of armor that almost chopped Candace's head off. Admittedly, it was due to power overload, but still...
** The giant gap in their maze which Candace, Isabella, & Melissa had to cross.
** Using the teleporter to get to the ground after launching themselves high into the air. Now think what would have happened if the teleporter had a malfunction...
** It became a major plot point in the episode "The Beak" when the boys built a set of power armor because they realized they otherwise won't survive their obstacle course.
* NoSnackForYou: [[ButtMonkey Poor Baljeet]] falls victim of this in "Ain't No Kiddie Ride".
* NostalgiaAintLikeItUsedToBe: See the example directly below.
* NostalgiaFilter: The kiddie rides outside the store that can be ridden for a quarter.
-->'''Phineas:''' You know, in retrospect, I may have over-romanticized those memories.
** In the future episode, when Candace claims she and her brothers were always friendly with each other.
* NoSympathy: Averted without shame, especially by Jeremy toward Candace. Unlike other series which would have Jeremy getting frustrated with Candace's constant shenanigans, her no-showing to their dates (due to Phineas, Ferb, Suzy, or any combination of the three), Jeremy is understanding and helpful toward Candace, always with a kind word or action to cheer her up after a seemingly ruined day.
* NoteToSelf: Perry utilises this to fight Doofensmirtz's brainwashing by writing "I Fight Evil" backwards on his chest, so he'll be able to read it in the mirror.
* NotMakingThisUpDisclaimer: Invoked by Monogram when describing Doofenshmirtz's scheme in "The Ballad of Badbeard".
* NothingIsTheSameAnymore: A series ''known'' for its extreme StatusQuoIsGod tendencies invokes this in "Happy Birthday, Isabella", when [[spoiler: Stacy learns about Perry's identity, and avoids getting her memories erased]].
* NotSoAboveItAll: Candace sometimes gets involved in the boys projects in a friendly way even while she's trying to bust them. "It's a Mud, Mud, Mud World" and "Spa Day" are but two examples out of many. Taken UpToEleven in "Finding Mary [[MacGuffin Mc]][[LampshadeHanging Guffin]]" when she ''gives'' them their project. (To be detectives.)
** Also done by Linda, of all people, with Lawrence and his brother.
--> Next time, ''destroy him''. Smear the punk. Annihilate him. Make him cry.
* NotSoImaginaryFriend: Steve the chameleon.
* NotSoStoic: [[http://www.youtube.com/watch?v=Ngy5J8haDHI Ferb's completely out-of-the-blue-46-second-long speech]] in "The Lizard Whisperer". This is coming from a guy who almost never makes any sort of facial expression or dialogue even in life-threatening situations!
** Perry has been given a few. A PlayedForLaughs example would be him [[ManlyTears crying]] while watching a soap opera in "Oil on Candace".
[[/folder]]

[[folder:O]]
* ObliviousToLove: Was a typical case with Phineas and Isabella, with Isabella making obvious advances towards him as early as the pilot episode, and him being so obsessed/distracted with his latest project that he fails to notice, but the "Summer Belongs To You" special [[UpToEleven takes the cake]].
** In a show known for [[LeaningOnTheFourthWall leaning frequently on the fourth wall]], this episode has Isabella singing an [[TearJerker adorably sad]] song about her affections for him, followed by a sour depression when he fails once again to notice her affections, all of which takes place in Paris (referred to by the various characters as "The City of Love"), but not a minute later, he laments for each of the OTHER unfortunate couples, who have very obvious attractions to each other, causing Isabella to shake in rage. All the while the idea of Isabella perhaps liking him is completely alien to him. Despite that, though, she does get a well-deserved hug from him later in the episode after she rallies him from an unrelated depression on his part.
** She gets an even sadder song in "Happy Birthday Isabella," where she is desperately singing that she'd be satisfied with increasingly small returns from Phineas.
** In an episode where Phineas is ''fully aware'' of everyone randomly breaking into song and non-discernible music sources (Rollercoaster: The Musical), he ''STILL'' doesn't notice Isabella and her song, "Whatcha Doin'?"
*** Alternatively, he may be hiding his own mutual feelings. This train of thought is given credibility by the events of the movie.
* ObliviouslyEvil: Baljeet, of ''all'' possible people, in "Cranius Maximus".
* ObviouslyEvil: Doofenshmirtz, in an [[AffablyEvil affable]] way.
** This apparently is a necessary trait to posses in order to be a member of the evil group "L.O.V.E.M.U.F.F.I.N". Watch the song "We're Evil", and try saying otherwise.
* ObviousObjectCouldBeAnything: In "Summer Belongs to You", Phineas and Ferb makes a series of machines to travel around the world, which looks ridiculously similar to famous world sites if put under a big cloth.
* OddFriendship: Buford and Baljeet, who are an [[JerkWithAHeartOfGold oddly sympathetic bully]] and a BollywoodNerd.
** Isabella and Candace are, as different as they are, on quite friendly terms. One might call them close acquaintances.
* OffModel: Isabella's height seems to vary; in some episodes she seems to be half a head taller than Phineas, in others she's just slightly bigger.
** Also in "Nerds of a Feather", Albert's glasses are noticeably thinner than in other episodes. (He's been in three, and Nerds of a Feather was the second, so it wasn't likely a design change).
** Does not help that there's close to five different animation studios (Creator/WangFilmProductions and Creator/RoughDraftStudios being the main ones) on the series.
** "Bubble Boys", done by Synergy Animation, is probably one of the most OffModel episodes of the series, (i.e. Doofenshmirtz's hand disappearing for a split second). The musical number "Yodel Odle Obey Me" must have been done in flash because of the animation being so off model.
** Sometimes Holly is drawn with a ToothStrip instead of her usual buck teeth.
** Candace's bare feet vary in size depending on which studio is animating the episode. Korean animators tend to give her bigger feet.
* OfficialCouple: Candace and Jeremy, by [[WordOfGod admission of Jeremy's voice actor]].
** In the show as of the episode "It's About Time!"
*** [[DepartmentOfRedundancyDepartment Officially-official]] as of Summer Belongs To You! with their [[spoiler:referring to each other as Boyfriend and Girlfriend and their first on-screen kiss.]]
** This also applies to Stacy and Coltrane (the bassist in Jeremy's band) as of "The Baljeatles".
** The episode "Brain Drain" now added [[spoiler:Vanessa and Johnny.]]
*** [[spoiler: And then dropped in "Minor Monogram", where Vanessa breaks up with Johnny. Though it adds ShipTease of Vanessa and Monty Monogram to compensate.]]
**** Who are now officially a couple as of "Druselsteinoween"
* OffscreenMomentOfAwesome: The majority of the rescue sequence in "Doof Dynasty".
** The Fireside Girls somehow literally moving an entire mountain.
* OhCrap: Happens to Doofenshmirtz a ''lot''.
** Perry, at the end of "Minor Monogram".
* OhWaitThisIsMyGroceryList
* OldShame: In-universe: Linda's "Lindana" career, though the creators themselves describe it as their "favorite thing" about her.
* OldTimeyBathingSuit: Klimpaloon.
* OminousMessageFromTheFuture: In "Phineas and Ferb's Quantum Boogaloo", a Candace from the future comes back to keep the boys inventing so that Dr. Doofenschmirtz can't take over the tri-state area. Different versions of her are met, but we never see more than three at once, as they're erased with their version of the BadFuture.
* OminousPipeOrgan: Doofenshmirtz plays one in "Bad Hair Day".
** {{Invoked}} in "One Good Scare Ought to Do It!"; the haunted house is controlled by Ferb playing one.
* {{Omniglot}}: Ferb knows Dolphin, Martian, Japanese, French, and pretty much whatever else the plot requires.
** Buford shows signs of this as well, he knows Latin and French and doesn't think much of it.
* OnceAnEpisode: The show ''runs on'' this trope. Every episode features one original song, a plan hatched by Phineas and put into action alongside Ferb, Perry trying to stop an EvilPlan created by Doofenshmirtz. Too many running gags to count. In later episodes, a good chunk of the comedy comes from {{Lampshad|e Hanging}}ing, parodying, and/or {{subvert|ed trope}}ing these.
* OneDialogueTwoConversations: Linda's first phone call to Lawrence in "What Do It Do?". Linda believes they're talking about the anti-romance rocket; Lawrence thinks they're talking about his birdhouse.
* OneOfTheKids: Both Linda and Lawrence have their moments, such as the latter geeking out over Pinhead Pierre Live in "Magic Carpet Ride" or the pair of them playing with a vacuum cleaner in "That Sinking Feeling".
** Doofenshmirtz has about the maturity of an 8-year old, on average.
* OnePersonBirthdayParty: Exaggerated and parodied in the backstory of Doofenshmirtz. He states that neither of his parents bothered to show up to his birth, and that he had to throw surprise birthday parties for himself. Also, at age eight, he was abandoned at the CaptainErsatz Chuck E Cheese to the point that the employees working there let him lock up the shop at closing.
* OneSteveLimit: Flamboyantly averted, enough to make you think the creators knew of the trope name. The boys lose their chameleon, which they named Steve, after Dooofenshmirtz' "Gigantinator" ray... [[AttackOfTheFiftyFootWhatever Well, what do you think]]? When they're looking for him, they discover an entire ''convention'' of people named Steve in the middle of Danville, which Steve told them about after they waved Steve off.
** A more subtle aversion: the time machine was invented by Xavier Onassis, while Xavier is also the name of Candace's future son. Made more interesting because they both start out as characters mentioned but never appearing...[[ContrivedCoincidence then appear for the first time in the same episode]], "Quantum Boogaloo" (though Onassis isn't referred to by name).
** Just recap how many characters were named Elizabeth among the years, including Rodney.
* OnlyKnownByTheirNickname: Ferb is short for ''something'', but nobody, not even his own stepsister, knows what it is.
* TheOnlyOneAllowedToDefeatYou: Doof and Perry.
* OnlySaneMan: Despite being a platypus, Perry plays the [[StraightManAndWiseGuy straight man]] to Doofenshmirtz.
** While Jeremy is in on the show's zaniness, once in a while, the viewer can see the FlatWhat expression on his face. Case in point:
-->'''Phineas:''' So if we just find mom, [[ItMakesSenseInContext we'll find]] ''[[ItMakesSenseInContext both]]'' [[ItMakesSenseInContext Candaces]]!\\
'''Jeremy:''' Uh... tell them I said hi...?
** Also Stacy when paired with Candace.
* OOCIsSeriousBusiness: Phineas is barely ever sad, scared or angry, but when he is...things are either teetering on [[DespairEventHorizon true hopelessness]], or sweet platypus, you are ''[[BewareTheNiceOnes screwed]]''.
** "The Lizard Whisperer": [[TheQuietOne Ferb]] must really love Steve the chameleon, because when Steve goes missing and Phineas and Isabella are on the verge of giving up the search, [[spoiler: he delivers a long and epic speech to urge them on]].
* OpeningShoutOut: {{Lampshaded}} by Ferb in "Swiss Family Phineas". The episode "Fireside Girl Jamboree" has a quick cameo by the unicorn-turtle thing shown with "discovering something that doesn't exist", with those words even used.
-->'''Candace:''' You're giving a ''monkey'' a shower?!\\
'''Ferb:''' Yep, had to be done.
** Happens again in both "Canderemy" (the boys build a giant robot dog, and the monkey is referenced again) and "Last Train to Bustville" (Ferb's list of things in the title sequence).
** And again in "Last Train To Bustville":
-->'''Phineas:''' A dodo bird! What's next on the list?\\
'''Ferb:''' [as he crosses out all but one thing listed in the opening song] Discovering Frankenstein's brain.\\
-->'''Buford:''' Aaahhh, that was in my balloon.
** They created nanobots in "Norm Unleashed" and made them form into word "Hello". Again, lampshaded.
-->'''Buford:''' Yeah, yeah, opening credits.
* OpenSaysMe: "Atlantis" has Phineas noticing a door with rune instructions on how to open it. Buford simply punches it and it opens.
* OrganAutonomy: Phineas and Ferb controlling Candace's arms and legs in [[FantasticVoyagePlot "Journey to the Center of Candace"]].
* OrphanedPunchline: Done fairly often, most notably in 'The Lake Nose Monster'. Lawrence Fletcher attempts to tell the boys about his capture of a giant fish named Big Mouth Ramon, but the boys leave. Through the episode, we hear snippets of this tale.
-->"A chilly April morning, 1980, disco was on the way out, and it was just beginning to dawn on everyone how ridiculous they looked in their...so it was either go up the fire escape or lose the pants altogether...I said, John, it's great, I love the tune, but the words! 'All you need is a Philips-Head screwdriver'? It just doesn't really ring true, now does it?...It seemed there was no way we could get through the entire petting zoo...and well, haha, and he was...and that was when I saw the way down, I saw Ted standing on the handles of the swing...so anyways there I was, four hours from the nearest dental supplies store, oh, there you are, Perry, and what a burglar I gasped...so I learned that it was too late, we were already headed off for Southampton...and that is the story of how I caught the Big Mouth Ramn."
** In "Leave the Busting to Us":
-->'''Candace:''' And then Ferb says...
-->'''Ferb:''' And that is why I will never wear suspenders in public.
* OtherMeAnnoysMe: This is also how Busting Candace seems to feel about Romantic Candace in "Split Personality"
* TheOtherRainforest: Humerously referenced in "Meapless in Seattle"
-->'''Isabella:''' But how can we tell when we're [in Seattle]?
-->(''It suddenly begins pouring and {{Grunge}} music plays'')
-->'''Ferb:''' We're there.
* OtherStockPhrases: Plenty, though many used in unexpected ways. 'Tis Phineas and Ferb, after all.
* OurWerebeastsAreDifferent: In "That's the Spirit!", we get a Doof as a WereCow.
* OutOfCharacterMoment: Buford suddenly changing from surly, arrogant boy who won't accept the fact that he lost to a girl to a humble, praising, fun person due to Doofenshmirtz's Misbehave-Inator in "Got Game?". {{Lampshaded}} by Ferb, too.
** Phineas actually yells angrily at Candace to "Get on the trike!" in "Summer Belongs To You!"
*** Invoked with Doofenshmirtz's ''Least-likely-inator''
* OutOfFocus: In "Vanessassary Roughness", Phineas does nothing but sit in a massage chair for the entire episode, leaving it to take a closer look at Vanessa and Ferb's exploits.
* OvenLogic: Stacy applies it in "Moon Farm", which is pretty foreboding considering she and Candace weren't even using actual food to begin with. [[spoiler:[[RuleOfFunny It works]].]]
* OvershadowedByAwesome: Candace. And who can blame her.
--> '''Candace:''' Why is it when Phineas and Ferb have an idea, everyone's like "Oh, wow, you guys are really clever!" and when I come up with something everyone's like "What, did you say something, Candace?"
* OverlyLongGag:
** Candace running and screaming all the way to the panic room in "I, Brobot".
** The "Fossils! Dun-dun-dun!" bit from TheStinger of "It's About Time".
* OverlyLongName: Aloyse Everheart Elizabeth Otto Wolfgang Hypatia Gunther Galen Gary Cooper von Roddenstein aka "Rodney".
** Some of Doof's inators, like the "Platypus Secret Agent Arrival In Order To Foil My [[EvilPlan Evil Plot]] Capture-Inator".
* OverlyNarrowSuperlative: Reversed. The teenage Doofenshmirtz isn't particularly fond of the song "What Do It Do?", even ''after'' putting it in one of these:
-->'''Doofenshmirtz:''' Eh, it's in my top seven, eight favorite songs about reverse engineering.
** Out of all the aquatic mammals Doofenshmirtz hangs with, Perry is the most uncooperative.
* OverprotectiveDad: Doofenshmirtz sent a man to another dimension once for hitting on Vanessa ("She's sixteen!" ''ZAAAP!'') Subverted with her crush/boyfriend Johnny, whom Doofenshmirtz apparently didn't mind:
-->'''Doofenshmirtz:''' ''(on Vanessa's birthday party)'': I took the liberty of going through your address book and inviting all your little friends! Including a nice fella named Johnny.\\
''[Vanessa looks horrified as something like a ScareChord plays]''\\
'''Doofenshmirtz:''' He had hearts by his name. I think I know what that ''meeeans''...
** In the in-character DVD commentary for "The Chronicles of Meap", Doof thinks that Ferb looks like a "hooligan" and is less than pleased when he starts hitting on Vanessa. He even mentions that he plans on warning Charlene not to let Ferb come hanging around their house.

[[folder:P]]
* PacManFever: The game in "Gaming The System".
* PaletteSwap: Candace's ball gown in [[http://phineasandferb.wikia.com/wiki/File:Candace_and_Jeremy_dancing_1.png "Happy New Year!"]] is just a recolour of the one she wore in [[http://phineasandferb.wikia.com/wiki/File:Candace_gets_a_ballgown.jpg "Gaming the System"]]
** Also regarding Candace, her bikini in [[http://phineasandferb.wikia.com/wiki/File:Candace_Relaxing.JPG "Phineas and Ferb Hawaiian Vacation"]] is just a recolour of the one [[http://phineasandferb.wikia.com/wiki/File:MA_Candace_in_a_Bikini.png she usually wears]].
* PandaingToTheAudience: Peter the Panda.
** Not that [[DieForOurShip the audience]] [[ReplacementScrappy liked it]].
* PantyShot: In "Ain't No Kiddie Ride" when the rocket is spinning upwards with Candace holding on. It's very hard to see at regular motion since they're the same color as her skirt. Usually this is [[MagicSkirt assiduously avoided]], though.
** Also in "Mommy Can You Hear Me?" when Candace is going to the backyard to tell her mom what was built in the backyard, she hops over to her and her skirt is flying up each time she hops and once more they are the same color as her skirt.
** Oddly enough those two incidents are nothing compare to what she really does but still doesn't get any upskirts. See "Run Candace Run" to fully understand me.
* PapaWolf: Dr. Doofenshmirtz. He may be [[CardCarryingVillain evil]], but he still loves his daughter a great deal and would do pretty much anything to keep her safe and happy. He doesn't succeed at this most of the time, but hey, he gets points for trying.
** He gets a CMOA one time when he covers himself in honey and taunts a swarm of bees so they will sting him instead of her.
* PaperThinDisguise: Doofenshmirtz is completely incapable of recognizing Perry without his hat. [[JustifiedTrope Partially justified]] in "Oh, there you are, Perry", when it was revealed there were so many platypi Phineas had to take a close look on all of them before being sure none of them was Perry.
** Also played with in that when Perry and Candace switch bodies, Doofenshmirtz can still recognize Perry by the hat.
-->"A teenage girl?" * Perry in Candace's body puts on his hat* "''[[http://www.youtube.com/watch?v=QXrpCCHWUfM Perry]]'' [[http://www.youtube.com/watch?v=QXrpCCHWUfM the teenage girl?!]]"
** In 'Oil on Candace', Doofenshmirtz wants to impress his professor, stating "Look, I even have my own nemesis!" only to receive the scornful reply of "He doesn't even have a hat."
*** All it takes is for Perry to simply do nothing and look dumb for a while for Doofenshmirtz to say "Well, I guess it's just a platypus. I could have ''sworn'' it was him!"
*** The movie suggests that one of the reasons alternate-Doof was so successful was that he ''could'' see through this. (Albeit the best one seems to be the fact alternate-Doof is better about keeping the self destruct button safe) Even after an extended scene with him trying to convience everyone the platypus was a secret agent, ''and'' Perry busting out of "mindless" pet mode, all the original-Doof can say is "Wait, I'm confused. Why can their platypus fight so good?" Remember: at this point, original-Doof already knew said platypus was named Perry. Alternate-Doof was frustrated Perry still needed the hat to be recognized by the original.
** Irving has to show his apparently insightful brother Phineas and Ferb, who are occupied, and hastily throws together bad costumes that Buford and Baljeet wear. He's ''stunned'' when it actually works.
** In 'The Lemonade Stand', when Perry shows up as a plumber, Doof doesn't question it at all, calling him "A platypus plumber". Then, when Perry dons his fedora, Doof calls him, questioningly, "Perry-The-Platypus Plumber?" When Perry scowls and removes the plumber's belt, THEN Doof yells in his usual inflection.
*** Doofenshmirtz actually didn't knew the plumber was a platypus until he removed his plumber hat. Then scalated from there.
** Perry uses it to his advantage again in "Ladies and Gentlemen, Meet Max Modem!". He's forced to do battle with a robot that has been programmed with all of Doofenshmirtz's knowledge of Perry's personality and battle strategies. He foils it by ''taking off the hat'', which confuses the robot and causes it to assume that the OWCA provided Perry with a cloaking device.
* ParanoiaGambit: Candace falls to pieces when the boys decide to take the day off and do nothing, and ends up building a project herself to try and encourage them.
* ParentalAbandonment
** The title characters are missing a [[DisappearedDad biological dad]] and a [[MissingMom biological mom]], respectively. However, their remaining parents are HappilyMarried to each other and have HappilyAdopted their stepchildren, so any issues with this are pretty much confined to FanFic.
** As a side-note, some fans have noted that throughout the whole first two seasons, [[MadScientistsBeautifulDaughter Vanessa]] seems to be the only child/teen character with two biological parents; everyone else seems to have a mom but no dad (or in Django's case, a dad but no mom). This recently changed when we finally saw Jeremy's father.
** Doofenshmirtz's parents couldn't even be bothered turning up for his ''birth.''
* ParentalBonus: By the bagful, though mostly in the form of obscure socio-cultural and literary references.
** Ain't that the truth! [[HinduMythology Hanuman Man]], anyone?
** "Rollercoaster: The Musical!" cuts to scenes of a dozen different broadway musicals that young children aren't likely to recognize.
** In "Get That Bigfoot Outa My Face!" Dr. Doofenshmirtz's "woodland retreat" is Falling Water by Frank Lloyd Wright. I'd wager not many kids got that.
** "Don't Even Blink" ends with Ferb lecturing Candace on the Copenhagen interpretation of quantum mechanics. Yeah.
** The ending scene of "Mommy, Can You Hear Me?" has a scene from Space Odessy
** "Phineas' Birthday Clip-o-rama" has a clip of Isabella as a beat poet, saying "I've seen the best girls of my troop hungry, badgeless and out of uniform". [[http://en.wikipedia.org/wiki/Howl Allen Ginsberg]] references for the pre-teens?[[note]] From the much-quoted poem "Howl" - " I saw the best minds of my generation destroyed by madness, starving hysterical, naked..."[[/note]]
* ParentsForADay: Phineas, Ferb and Candace are all left to care for "[[YourTomcatIsPregnant Perry's]]" egg in "Perry Lays an Egg" [[spoiler:As it turns out, it was just a very unusual bird.]]
* PassiveAggressiveKombat: Isabella and Adyson at the beginning of [[LowerDeckEpisode "Isabella and the Temple of Sap"]]. Their relationship is generally amicable, though.
* PercussiveMaintenance: In "Hide and Seek": "What do you know, random pounding ''works''!"
* PeripheryDemographic: In universe, Ducky Momo is implied to have one that includes Candace and even (as hinted in "My Fair Goalie") ''Major Monogram'', though at the same time it also appears to have a large PeripheryHatedom.
* PeripheryHatedom: In Universe, Ducky Momo. Unfortunate for Candace who lies well outside the target demographic.
* PerplexingPlurals: In "Greece Lightning", the narrator of an educational filmstrip is unsure how to refer to platypi. Platypuses. Platypeople?
* PersonalityPowers: The neighborhood kids imagine themselves as superheroes with such abilities.
** Except for Ferb, who wound up as a BadassNormal; possibly FridgeBrilliance, considering his usual role.
* PersonaNonGrata: Doofenshmirtz is "never welcome in Albania ever again" for reasons involving [[NoodleImplements a bunch of Canadian college students, a rivalry with a guy named Dylan, and a complaint from the ambassador's wife]].
* PetTheDog: In "Voyage to the Bottom of Buford" Dr. Doofenshmirtz gets good publicity after accidentally saving a kitten.
* PhonyDegree: Dr Doofenshmirtz got his doctorate online for $25.
* PhraseCatcher: "Perry The Platypus!". Perry get these a lot. (Although Phineas does get "Whatcha doin'?" from characters other than Isabella on rare occasions). Hell, he even delivers it on occasion. (Isabella doesn't mind when ''he'' does it).
* PigLatin: "Ferb Latin". You take the first letter of every word, you move it to the end, and then say -erb!
* PinballGag: Part of the boys' and Candace's subplot of "Bowl-A-Rama Drama".
* PintsizedPowerhouse: Meap and many of the animal agents, but especially Sergei the Snail.
* PlayAlongPrisoner: Perry has a distinct tendency to stay in a trap and break out and stop Doofenshmirtz at the very last second. In "Greece Lightning" he was trapped by chair-cuffs, removed his hand to grab some popcorn, then ''put it back''.
** In "Candace's Big Day", after Doofenshmirtz had been stuck in an elevator and Perry has entered his apartment, Doof tells him that he "at least could've gotten into [his] trap" (it was on the coffee table). Perry does so while Doof explains his plan.
** Doofenshmirtz seems to even be aware of it, he gets very miffed at Peter the Panda when he does not wait out the VillainSong.
* PlayedForLaughs: All the torment that Candace, Doofenshmirtz and Baljeet go through.
* PlayingPictionary: In "Put That Putter Away", Candace apparently has such poor handwriting that when she writes the word "busted" on a piece of paper, both Stacy and Phineas mistake it for [[StrangeMindsThinkAlike a drawing of dancing weasels.]]
* PlotHole: The classic knowledge version, during the birthday clip show, Phineas flashes back to things he never saw. And Irving has footage of things that happened in dreams, in alternate timelines, and that were supposed to have been erased from every computer and memory in the world.
* PlumbersCrack: Perry once disguised himself as a plumber wearing nothing but a plumer's hat and a plumber's belt. Doof felt the natural disgust during the few seconds Perry actually did some plumbing.
* PlutoIsExpendable: In "Science Fair Unfair", a kid enters with a project on Pluto. Doof insults his project, quoted in the trope. Needless to say, the kid was just holding it for his brother, who gave Doof a beating.
* PointyHairedBoss: Major Monogram. Consider this: He refuses to ever give Perry a vacation, even though he only ever pits him against an IneffectualSympatheticVillain that any ''marginally'' competent crimefighter could've handled easily. And you sometimes get the impression that he haven't bothered to do any research on said villain's activities recently ("Uh...Stop Doofenshmirtz"). Heck, one time Heinz actully ''called in sick'' to be bothered with their usual routine. Monogram's response ''while he was sick no less'': "How dare he call in sick when everyone already gathered. Screw that, were going on as planned!".
* PokeThePoodle: Doofenshmirtz ''lives'' this. In the case of "Perry Lays an Egg" the Doctor actually had a scheme so ridiculous that Perry came to investigate, saw the entire plan... ''and [[ScrewThisImOuttaHere turned around and left without even bothering to stop it]]''. Doof then spends the rest of the episode [[CrowningMomentOfFunny chasing Perry, popping into every place he tries to hide, and demanding, "Thwart me"!]]
** Khaka Peu Peu indulges in this until he gets to fight The Beak.
* PoliticiansKissBabies: In the episode "The Mom Attractor," Dr. Doofenschmirtz's evil scheme is to create a giant baby that cries whenever his brother (the Mayor) kisses a baby, so people won't vote for him.
* ThePollyanna: Phineas, who has near-constant optimism and a can-do attitude. Because of this, he quite literally ''can'' and ''does'' achieve the impossible, [[OnceAnEpisode every episode]], with the help of his friends and family. That being said, he can occasionally [[HeroicBSOD crack]]...
* PoorCommunicationKills: More like (very) Poor Reading Skills Kill, but... Candace receives a text message from Stacy saying "CYL. BFF. S." Candace misreads this as "Candace, you loser. Bad friendships fail. Stacy." What Stacy actually meant was "Call you later. Best friends forever. Stacy."
* PoorlyDisguisedPilot: "Isabella and the Temple of Sap". A ''NY Times'' article, back in June of 2010, brought rumors of a possible spin-off show focusing on the Fireside Girls. The above episode would probably be the closest thing you would get to it. The creators said in another roundtable dicussion that they are still considering doing it.
** In an article that surfaced on the internet around August of 2011, it was reported that Disney has hired them to do a pilot for potential SpinOff (or another show entirely) but whether or not it will be this, well wait and see.
* PowerArmour: The Beak.
* ThePowerOfRock: Perry uses the highest voted ''Phineas and Ferb'' music video to counteract Doofenshmirtz's scheme in the "Cliptastic Countdown". Somewhat justified in that said plan involved a [[MindControl mind-controlling]] [[EarWorm song catchy enough to get stuck in its victim's heads]].
** * hypnotized* ''His name is Doof... and I'll do what he says...Whoop whoop!"
** Also to a certain extent in "Dude, We're Getting The Band Back Together", especially "Danny's Story".
** Perry also employs this when he drives away a herd of aliens in "The Lizard Whisperer".
* PreAssKickingOneLiner: Ferb-a-lot gives a rather lengthy one in "Excaliferb"
--> '''Ferb-a-lot''':Behold evil wizard Millifishmirtz, I hold the sword Excaliferb. This mystical vorpal blade was given to me by The Lady of the Puddle. Get a good look at it, for it is the instrument of your demise! ''(The blade of the sword falls off the hilt)'' Well, uh, okay. So big deal, the end comes off.
* PrecociousCrush: Ferb has this on Vanessa.
** Irving is attracted to Candace and Stacy, judging by "Moon Farm".
* PreemptiveShutUp: Doofenshmirtz to Perry: "I'm not an idiot! ... And not one word out of [[TheVoiceless you]]."
* PrehensileHair: In "Canderemy", Perry manages to get out of his trap by [[spoiler:picking the lock with the three little hairs on his head.]]
* PrepositionalPhraseEqualsCoolness: "He's a semi-aquatic, egg-laying mammal OF ACTION!" Platypodes just became BadAss.
** [[EverythingsBetterWithPlatypi I thought they had always been]] {{Badass}}.
* [[PrinceAndPauper Princess And Pauper]]: "Make Play".
* PrettyBoy: Jeremy, very much so.
* PrettyInMink: Isabella and the Fireside girls wear fur-trimmed coats in "S'Winter".
* PrincessForADay: Happens to Candace in "Make Play".
* PrisonEpisode: [[http://www.youtube.com/watch?v=8MJwAMY9B1c Phineas And Ferb Get Busted.]] While what they are sent to is called a reform school, it is most certainly run like a prison.
* PropheticName: Dr. Doofenshmirtz. "Doof" means "stupid" in German (though it's not pronounced like in the show) and "Schmerz" means "pain".
* PuffOfLogic: The BadFuture adult Candace disappears in one of these after Phineas points it out to her that said bad future had been undone. However, she wasn't technically ''from'' the BadFuture.
** No, but she was the Candace that busted the boys that ''created'' the bad future. Stopping the busting from happening meant that the Candace who ''discovered'' the bad future (aka the one who did the busting) didn't logically exist since, well, she didn't bust the boys.
* PullARabbitOutOfMyHat: Dr. Doofenshmirtz tried to become a StageMagician in his youth, but his tricks always ended up with him getting sprayed by a skunk.
** Also, after he first recounts his failure to do this, he makes Perry disappear with a trick. Naturally, Perry later jumps out of Doof's hat and beats him up.
* PunchClockHero: Perry The Platypus dons his hat and does his duty as a secret agent whenever Monogram contacts him. The rest of the time he doesn't do much.
* PunchClockVillain: Suzy Johnson is revealed to be one of these in the episode "Suddenly Suzy".
-->'''Candace:''' Aren't you going to do something horrible to me?\\
'''Suzy:''' Oh no, making you look bad is just one of the ways I [[ManipulativeBastard control Jeremy]]. If he's not here, [[PunchClockVillain I'm off the clock!]]
** Doofenshmirtz comes off like one of these. His MadScientist activities really are treated more like his job than anything he does for personal enjoyment. {{Lampshaded}} occasionally when Perry the Platypus bursts in on him doing nothing particularly evil.
-->'''Doofenshmirtz''': It occurs to me that all this machine does is open and close a lobster cage, so, you know, that's not even illegal, much less evil.
* PunctuatedForEmphasis: From "The Chronicles of Meap":
-->'''Mitch:''' You're all trapped! On my ship! FOREVER!!
* PungeonMaster: Doofenshmirtz. Phineas also has hints of this, mostly in 'A-G-L-E-T' and 'The Beak'.
* PuppyDogEyes: Phineas uses these on Candace at the end of "The Lake Nose Monster". [[spoiler:It works.]]
** Ferb also got these in "I Scream, You Scream" when he sees [[HelloNurse Vanessa]].
** The Fireside Girls use these when selling their cookies, prompting Dr. Doofenshmirtz to build an invisibility ray.
** Candace gains a pair of these in "Perry Lays an Egg" while watching an AnimalPlanet parody.
*** She also attempts to use these on her brothers in the episode "Suddenly Suzy". [[TheUnSmile It]] [[NightmareFace fails]] ''[[NightmareFuel horribly]]''.
** Also done by ''Major Monogram'', of all people, in "Perry the Actorpus"
** Doofenshmirtz gives himself a pair of these in attempt to earn the pity of others in "Blackout!".
* PuttingTheBandBackTogether: In the appropriately titled episode "Dude, We're Getting the Band Back Together!". It even provides the page quote.
