These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
One fan decided to look a little too far into the scene in "De Plane! De Plane!" when Candace and Jeremy crash into each other in the dried up pool. The results were, reportedly, scarring, though the video has since been taken down.
Perry trying to go through the rubber hose to get into his lair in "Thaddeus and Thor". His movement combined with that noise...Yeah...
When Linda calls Candace near the end of "Lawn Gnome Beach Party of Terror!", Candace's practically orgasmic voice really turns the conversation straight to this.
Linda: Candace, is everything okay?
Candace: Oh, everything is just wonderful.
Linda: And... Phineas and Ferb? What are they doing?
Candace: Oh, such wonderful things.
From "Journey to the Center of Candace": "When we're inside, we'll activate the shrinkage."
Doof's line from Phineas and Ferb Interrupted: "...new partner, now if you'll be kind enough to point it to my face and blast me, I'll be the most fascinating and charming person in the Tri-State area! And then maybe we'll go to a movie or something."
Phineas: Is he reallythat naïve, or just better than Isabella at hiding his own burning affections as implied by how thrilled he was about Isabella kissing him.
Some see the show as Candace's visions of madness, rather than about a show about two brothers who build things.
Is Candace a Jerk Ass who deserves all what happens to her for trying to bust her brothers or do we feel sorry about her life where Failure Is the Only Option because she is the only sane girl who realizes that building impossible things in a backyard may end very badly?
Some think the O.W.C.A. are a Big Brother analog. Doofenshmirtz can't even go to the park without the agency sending Perry after him! Not to mention they give Perry very few days off or vacations, not even on Christmas.
Is Isabella a sweet Girl Next Door kinda neighbor with a crush on Phineas, or is she a Bitch in Sheep's Clothing with an obsessive crush and won't even care what happens to anyone, as long as she has Phineas?
Eh, given that it was one short line in an otherwise delightful episode, it's more of a tap on the shoulder than a heavy hand.
The mandatory healthy eating episode was "Candace's Big Day". Interesting in how, if you look at the labels on the "Junkfoodinator", they read "Corn Syrup" (Which Dr. D refers to as "High Fructose Corn Syrup") and "Partially Hydrogenated Coconut Oil", as a bonus for health-nuts out there.
Also notable as a "Health Food Episode" that actually makes sense: Doof picks the scheme because he expects everyone to become "overweight and lethargic" as a result of eating only junk food, making it trivial for him to take over. It can also be seen as exactly the kind of plan Doofenshmirtz would come up with.
Similarly, "Act Your Age" uses the term "Phinabella".
Ass Pull: Like you got no idea. However, it's due to being a mere parody of making machines that would take 100 expert people 1 year to construct, while two kids construct it in 5 minutes. See also Deus ex Machina.
Award Snub: The show has so far lost six times in a row to Spongebob Squarepants in the Kids Choice Awards. It is Nick's award show after all, and SpongeBob is a much bigger phenomenon than this is, so those losses are understandable. This is obviously ticking some fans off. Made worse in 2014, when a new award - for Best Animal Sidekick - pit Perry against Patrick. Patrick won.
Irving's either hilarious or just plain annoying, depending on who you ask. The fact that he only occasionally appears at all helps to keep the fandom from fighting, though.
Candace. She has enough fans to be popular, but also many people who see her as The Scrappy. To elaborate, many people hate her for wanting her brothers to get in trouble, even if their project isn't dangerous, blaming them for things that weren't even their fault, and whether or not she's a good friend towards Stacy and Jenny is questionable. Other people don't see anything wrong with Candace busting her brothers since the things they build and the activities they partake in are dangerous and she's just doing it because she fears for their safety and also point out that she can be fun when she wants to be and there are moments when she's actually nice to her Phineas and Ferb like a normal sister towards a normal brother.
Isabella. Basically, if one does not ship Phinebella, nor find her cute or likable, then odds are they will consider her a Purity Sue.
Better on DVD: Though plenty of entertainment can still be drawn regardless of what order you watch the episodes, watching multiple episodes in a row, especially the earlier ones first, will allow you to understand more of the jokes made in the show, since a huge chunk of its later humor is based on lampshading and subverting the Running Gags and making Brick Jokes and Continuity Nods to other episodes. It would be, if there were more than a dozen episodes (of the over 150 made) available on DVD. Although they are all available on Netflix, it's only in America. Outside of the US, they can be bought on iTunes.
Big Lipped Alligator Moment: The popularity of the "Gitchie-Gitchie-Goo" song in "Flop Starz" led the higher ups to decide to make the musical numbers occur Once an Episode. That includes when it really doesn't make any sense to have a musical number whatsoever. The writers do their best of course, but sometimes there's just no way to work a song into the plot of an episode. And yet there's one there anyway.
Of course, considering that every freaking song on this show is a nuclear-powered Ear Worm, this is definitely an example of Tropes Are Not Bad.
The fact that it doesn't make sense for a song to be there makes it even funnier when there is, anyway. Mexican Jewish Cultural Festival, anyone?
"Izzy's Got The Frizzies", relating to the above. A completely unrelated 70's funk number crammed in before the credits of "Robot Rodeo". Strangely enough, that episode already had a song.
"Dance, Baby" appears at the end of a perfectly normal conversation between Perry and Doof, and it comes completely out of the blue.
The Tokyo song in "Summer Belongs To You". It's even lampshaded.
Candace: [while doing the Caramelldansen movements] I have no idea what just happened.
In-universe, Perry & Doof's interference with the main plot comes out of nowhere from the kids' point of view, but they rarely question it and almost never bring it up after the fact.
Phineas: I don't know what causes it but it sure helps with clean-up.
"Phineas' Birthday Clip-o-rama" actually shows a montage of Big Lipped Alligator Moments (courtesy of Baljeet), some of which don't come from any actual episode and are impossible to imagine making sense in any context.
Speaking of which, "Phineas' Birthday Clip-O-Rama" is littered with clips of events that never actually occur in the series, such as Perry entering his lair as a giant and getting trapped in a metal shell shaped exactly like himself, pose and all, Doofenshmirtz's Blow-Itself-Up-Inator and Inside-Out-Inator, Candace calling for Mom while she and everything around her looks like an abstract painting, a project of Phineas and Ferb's that involves a device apparently being powered by chickens, and, of course, Evil Lawrence and Evil Linda.
"Tip of the Day." The lack of another mention is justified as everyone but Candace forgot about the whole thing near the end. (A clip is shown in the clip show, so apparently Irving remembers (if only due to his spy cameras), and that somehow goes for "Phineas and Ferb Get Busted" (see Dream Within a Dream).)
"Lost in Danville" didn't seem to be one at first, but the ending revealed that everything happened in an alternate dimension, being observed by our Phineas and Ferb. Observant viewers might have noted the subtle clue in the episode that points that out, and is lampshaded at the end of the episode.
Similarly, the fanbase is broken on whether the show focusing less and less on the titles characters is a good thing or not.
Whenever Phineas gets angry seems to spark a wide range of opinions. In both Across the Second Dimension and "Mission Marvel", Phineas gets angry (the former at realising that Perry was a secret agent, and the latter for Candace's fangirl excitement continuously causing her to screw up the plans for the superheroes to regain their powers), and people either consider it justified given the circumstances or consider it enough of an Out of Character moment that he delves into Jerkass territory.
Phineas also gets mad briefly in "Summer Belongs to You", but this doesn't seem to split the fan base as much.
Canon Fodder: Oh boy, "Who is Phineas and Candace's biological father, who is Ferb's biological mother, what happened to them and where are they now?" If there was an earthquake for every fic written related to this, the world would be over in minutes.
Cliché Storm: Done deliberately with the Doofenshmirtz and Perry subplot. Half their shtick is taking just about every single Hero/Supervillain cliche in the book, and parodying, lampshading, deconstructing, and playing with them to kingdom come.
Continuity Lock-Out: There are many episodes that focus specifically on playing with the usual formula and/or build directly on top of previous episodes.
Crack Pairing: So many of them get thought up on the Phineas and Ferb Wiki. The constant preferences of nonsensical pairings like Baljeet/Linda and Katie/Doof drives people mad.
Crazy Awesome: Phineas and Ferb's schemes, Candace in full flight.
Crosses the Line Twice: For an animated program on Disney Channel, this happens with startling regularity— mostly in Harmless Villain Doofenshmirtz's Imagine Spots. An obvious example is the time he planned to found a college of Evilology and, among the projects, the audience was shown the (smoking) skeletal remains of an infant. Another can be found in the episode where he planned to use a space laser (inator) to destroy stuff. Including morning talk show hosts. After (theoretically) using it, the host's arms are still intact, clutching at his mug of coffee. The rest of him is nowhere to be seen.
Ensemble Darkhorse: With the fanbase the size as it is, a case can be made for most (if not all) secondary characters, with the Fireside Girls (Gretchen in particular, since some fans pair her with Ferb) being the most prominent examples.
Eliza Beckham Fletcher, it is unlikely she will show up again yet she already got a sizable fanbase following less than 2 days after the one episode in which she does aired.
Vanessa Doofenshmirtz also has a huge fanbase.
As for background characters, the female backup dancer with the brown hair in the "S.I.M.P." song and "A Real Boy" has gotten a lot of attention. To the point where she got a speaking role and a Fanservice Pack in the Halloween special "Night of the Living Pharmacists".
Epileptic Trees: A lot of fans were once convinced that Heinz Doofenshmirtz is Phineas and Candace's biological father, to the point where the creators themselves had to step in and give it the boot. Despite this, many fans still believe this theory to be true.
Making it worse is that Doof's the only one other than Lawrence who's been seen dating Linda (granted, it was the 80's and ended poorly).
Evil Is Sexy: Vanessa, although not technically evil (according to her, anyway).
She is eviler note "I don't think that's a word." than almost all the cast, what with her stealing a Vespa, threatening people with a faux deadly weapon, and snatching a doll from a little girl.
Foe Yay: Doofenshmirtz and Perry seems to be a parody of this, with their interactions being explicitly treated like a romantic relationship at least half of the time.
"It's About Time!" was just full of Foe Yay, with Doofenshmirtz getting a new nemesis actually presented as an affair. Perry was heartbroken.
You know they had the fans of that pairing just squealing over that moment, during "Swiss Family Phineas", where Perry and Doofenshmirtz get thrown in the 'BIG' laundry... cue costume change, with a wedding dress and tuxedo. Just guess who's in the dress.
And in "Gaming the System", after Doofenshmirtz zaps Perry with the Ball-Gown-inator, he can't stop going on about how elegant Perry looks.
Doofenshmirtz: You know, Perry the Platypus, that dress sort of suits you... you know, you just accentuate the positive, as they say... Um... I'm going to stop talking now, I'm moving into a weird area.
In "Nerds of a Feather" after Doofenshmirtz fails to get his show "Doof and Puss" on the air because he wouldn't let the producer give the platypus a girlfriend, we instead get the show "The Platypus And His Girlfriend", with the girlfriend seeming to play the same role as Doof did in the original show.
Baljeet and Buford also get their fair share of Foe Yay as well. "Bully Bromance Breakup" essentially throws all subtext out the window.
"Funny Aneurysm" Moment: In "Summer Belongs to You", Doofenshmirtz's evil plan is to drop a giant water balloon on Tokyo to flood out the Annual Good-Guy Convention. This was almost a year before the infamous quake in Japan that caused massive flooding.
There's an active Japanese fandom as well, if you go to the "overseas cartoon" section on 2ch, there will almost always be a thread for Phineas and Ferb near the top.
Growing the Beard: Somewhat expected, considering a lot of the show's humor and wit come from lampooning, subverting and lampshading the conventions and practices that would take a few episodes to establish.
Although, in terms of quality though people could spot differences from other shows at the time beforehand, it was Phineas and Ferb Get Busted that arguably showed us just what this show was truly capable of.
Hell Is That Noise: Baljeet's "Fail Wail" in The Baljeatles. Seriously, the sound makes you think of some kind of animal, likely a cat, in very severe pain. Even Phineas couldn't stand it.
Cheer Up Candace featured the "Mix 'n' Mingler", a machine used to introduce Candace to random new people every few seconds. Among these people included some...less than desirables such as a man who likes to take off his pants. The episode first aired in October 2009, about a month before the creation of Chatroulette.
Doofania, which featured, among other things, banners with Doof's name or "Evil" printed on them. In this case, there were only a few, but guess what are scattered around the other Danville.
It's the Same, Now It Sucks: "It's too repetitive" is probably the most common complaint people who dislike the show give, though later seasons have been playing with the show's episode formula quite a bit, so this isn't holding up as well as it was before.
Magnum Opus: For Dan Povenmire and Jeff Marsh, and to an extent, Disney TV animation.
Marty Stu: Phineas tends to be able to do anything without repercussions of any kind. One example of Tropes Are Not Bad, though, as this does not seem to make him less likable as a result, and there have been instances where this trait of his has been averted. (The Dream Within a Dream sequence where he finally gets busted springs to mind).
This has been played down in later episodes, with Phineas being better developed as a character, along with Ferb to a lesser extent.
Isabella could qualify too
Ferb as well. Although his quiet personality downplays it, he has more skills and abilities than Phineas. Phineas himself is pretty much constantly going on about how awesome Ferb is (particularly in earlier episodes)
Parallel Doofenshmirtz from The Movie crosses this when he tries to kill Perry, Phineas, Ferb, Candace and normal Doofenshmirtz via a lava-filled death trap. Though he already wasn't far from there, since he brainwashed the Perry of his dimension into being his cyborg slave, his dictatorship of the Tri-State area forced the Parallel Phineas and Ferb to live a sheltered, reclusive life without fun or summer, and Parallel Candace to essentially lose her childhood.
Doofensmirtz's parents cross it when forcing him to be the family lawn gnome among many other things.
The Drill Sergeant Nasty from "Phineas & Ferb Get Busted". He utterly destroyed the spirits of the title characters just because they were creative. Thankfully, he doesn't actually exist on the show.
Liam McCracken from "Primal Perry". Not only did he plan to make Perry into a trophy, but Doofenshmirtz (who hired him to trap Perry) as well.
Narm: At the climax of "Summer Belongs to You", it may be nice to see Candace become more optimistic, but hearing every one of the kids (except Ferb) encourage her by saying "I BELIEEEEVE!" is pretty cheesy.
Narm Charm: Half the times Phineas is sad, angry or just generally morose. More often than not, what he says aren't exactly the most original dramatic lines ever written, but since he's...well, Phineas Flynn, it's still very possible to take him seriously (Unless you're not supposed to).
The death of Ballony.
Nausea Fuel: In "Hide and Seek", the kids are shrunken to miniature size, and Baljeet is stranded on a ceiling lamp with the air conditioner blowing right at him. He avoids freezing to death by hiding inside the exoskeleton of a dead fly. This probably makes for good Nightmare Fuel, too.
Baljeet's brain in "Cranius Maximus". It's basically swollen up to the point where it's larger than the rest of his head and barely staying inside his skin.
Never Live It Down: Fans seem pointedly fixated on the one time Phineas has ever yelled at anybody (Candace in "Summer Belongs to You"). Case in point, look how frequently it comes up on these pages.
Based on this wiki, fans seem to have latched on to Charlene's one-time statement of "No one's evil," taking it absolutely literally as evidence that she's hopelessly naive, rather than accepting it as a simple sweeping generalization meant to dissuade that silly notion of Vanessa's that her father's evil.
And considering that she was married to Heinz Doofenshmirz, can you really blame Charlene for not taking self-proclaimed "evil" people seriously?
No Yay: Suzy's relationship with Jeremy gives of seriousYandere vibes.
The Scrappy: Suzy is one once due to how relentlessly cruel (and creepy) she is. Indeed her appearances on the show have become less and less.
Some consider Baljeet The Scrappy, since he's a one-joke character and an ethnic stereotype.
Seasonal Rot: Some fans of the show think the episodes from the middle of the third (for some, the second) season aren't as good. That said, the show is still quite good - as far as Seasonal Rot goes, P&F manages to get off pretty easy, what with the show still being of a pretty good quality.
Ship Mates: A good portion of Phineas/Isabella shippers will just pair off the rest of the boys/girls in the group. The most common ones are Ferb/Gretchen, Baljeet/Ginger, Buford/Adyson, Django/Milly, and Irving/Katie. Notice how they don't take Ferb's Precocious Crush on Vanessa into account.
Phineas/Ferb fans will almost always ship Jeremy/Candace.
And to a much lesser extent Ferb/Isabella and Phineas/Django.
Signature Scene: "Get on the trike!" is easily the most remembered part of "Summer Belongs to You".
Strawman Has a Point: The "Give Up"-song: Candace gives up trying to bust her brothers (though Comically Missing the Point her aunt was making), only for her aunt to convince her to never give up. While "never give up" is usually a good aesop, when Candace gave up she stopped stressing out and relaxed.
Suspiciously Similar Song: Those with an expansive memory of music in pop culture, as well as a sharp ear, will realize most of the best numbers are heavily-altered versions of already famous songs.
Aaron Copland's Fanfare for the Common Man is heard in "Rollercoaster" and elsewhere.
"He's a Bully" in the episode "Raging Bully" sounds like the Jimmy Hart version of "Eye of the Tiger".
The instrumental that plays during Candace's hallucinations in "Badbeard" (with the droning sitar/tanpura and backwards drums) sounds like the Jimmy Hart version of "Open Up Said the World at the Door".
The showstopper "Summer Belongs To You" from the hour-long special is clearly ripped from "You Can't Stop The Beat" from Hairspray.
"Better With Perry" from the TV movie has an arrangement extremely similar to "One More Chance" by the Jackson 5.
"Ducky Momo" appears the be this universe's equivalent to Barney the Dinosaur and other such sugary-sweet toddler shows, which is probably why Candace catches so much grief for liking it (or believes she would).
Jeremy and the Incidental's song from "The Best Lazy Day Ever".
Isabella's pony from "The Magnificent Few".
Isabella herself can be this, especially her voice. Lampshade in "Meapless in Seattle".
Meap's Planet. According to him, cuteness is valued above all other things on that place.
It doesn't help that was kinda bland. Or at least, he didn't have a single defining trait like most of the main cast do.
Well, he was good at art.
They Wasted a Perfectly Good Plot: Candace gets the idea to try and slow down the boys' construction rate in "Mom's in the House". Problem is that once she gets the idea, Phineas and Ferb have already finished building their latest invention.
"The Doonkleberry Imperative" features Candace going with Vanessa to Doofensmirtz's apartment to use the scientific method to bust Phineas and Ferb. We never get to see her actually doing this.
"Mandace" from the premises seemed to be a Gender Bender episode. Turn out that the plot concerned Candace disguised as a normal pizza-guy through a simple hologram (due to one of the inventions of Doof).
Toy Ship: Multiple. The most prominent of these would be Phineas and Isabella.
What an Idiot: In "Candace Disconnected" the boys give Candace a phone with an app that will send her to anywhere she wants just by saying "Go to" followed by the destination. She leaves before they can tell her about the app and then ends up accidentally transported to Easter Island. She just assumes transporting you to Easter Island is the app's one function. Even after being accidentally transported twice, she still hasn't figured out how it happened.
Phineas, Ferb, and their friends fail to realize that Candace is wearing a camera in "Leave the Busting to Us," even though she was right in front of them when she put it on and when she talked to the Bust 'Em producer about getting footage of the water slide.
Or they just don't care. They don't see anything wrong with their projects, after all.
Phineas's Oblivious to Love has always been a bit face-palm inducing, but it officially drops to idiot levels in "Summer Belongs to You". Especially, during the "City of Love" song.
Isabella. She doesn't bother to tell Phineas how she feels, because it seems like she waiting for Phineas to 'make the moves first. She should either just admit to Phineas how she feels or just give it up! note This is fairly common in real life however, with one side or even both being afraid/unable to do either.
The fact that Klimpaloon is a living, talking bathing suit that lives in the Himalayas.
The giant floating baby head, anyone?
The Woobie: The main example is Doof. As a child, he had to throw his surprise birthday party. His father named the dog "Only Son". When he was born, neither of his parents bothered to be there. He was raised by ocelots. The list goes on and on ...
Candace. One must feel sorry for how hard she has to try to bust her brothers, even if her determination can be irritating to some. Also in "Candace Gets Busted," where she gets punished by her mom for throwing a party that was out of her control and which she legitimately didn't want. But it really comes out in "Nerds Of A Feather".
Taken to a new level in "Mission Marvel" where all she wants to do is help, but keeps messing up. It's made even worse by how bad she feels about it, and a horribly sad song.
Her crippling self-esteem issues make it impossible for her to accept that Jeremy loves her for who she is and that she doesn't have to keep trying to impress him.
An odd one, but Buford in "Voyage To The Bottom Of Buford". In his song, he was shown to be so lonely he was playing ping-pong with his goldfish!
Everyone else being too disturbed by his out of character behavior to comfort him just makes it worse.
Phineas' obliviousness to love can put Isabella into this territory, especially during her song "City Of Love" in "Summer Belongs To You." She gets over it, and also gets back at him by kissing him right before he was about to voluntarily get all of his memories of the previous day wiped out.
Norm becomes one officially in A Real Boy.
Phineas, who is normally unbelieveably cheery and innocent, completely breaks down when things start going wrong. (See Summer Belongs to You, Christmas Vacation, and The Movie.)
Doofenverse Phineas and Ferb from Across the 2nd Dimension. When DoofenPhineas is hugging Perry if you don't go "Awww." you have no soul.
