Trivia / Phineas and Ferb

Trivia for Phineas and Ferb.

Regular Trivia:

• Both Swampy Marsh and Dan Povenmire wrote for CatDog and Rocko's Modern Life. Both shows feature multiple minor characters with the name "Ferb".
• Three different cast members from The Rocky Horror Picture Show have lent their voice to the series. Richard O'Brien (Riff Raff) has a main role as Lawrence Fletcher. Barry Bostwick (Brad Majors) appears in several episodes as Grandpa Clyde. And Tim Curry (Dr. Frank N. Furter) guest-starred as one-time characters Stubbings, Dr. Lloyd Wexler, and Worthington Dubois. However, except for one brief moment on the show (see below), none of the actors interact with each other apart from a brief, awkward conversation between Lawrence and Clyde in "The Last Train to Bustville".
• Also 3 Lexx guest stars: Barry Bostwick (Thodin), Tim Curry (Poet Man), and Malcolm McDowell (Yottskry the Divine Cleric).
• Phineas and Ferb made a guest appearance in an episode of Extreme Makeover: Home Edition in which they build a shrink ray to help Ty Pennington destroy a house.
• Unlike most other shows, the cast does not record the scenes in the same room or even at the same time. Vincent Martella (Phineas) claims to have waited 2 years before meeting Thomas Brodie-Sangster (Ferb) in person. Part of the reason is that Thomas Brodie Sangster records his dialogue in England while the rest of the main cast is in America.
• Interesting parallel: Vanessa Doofenshmirtz is the non (or slightly less) evil child of a Harmless Villain, who constantly snarks at his parenting attempts, similar to Scott Evil. Fittingly, her boyfriend Monty is played by Scott's actor, Seth Green.
• Across the entire series, there is a grand total of four episodes which do not feature any songs: "Rollercoaster", "Lights, Candace, Action!", "The Lizard Whisperer", and "Mommy, Can You Hear Me?". Every other episode includes at least one musical performance.

Trivia Tropes:

• Accidentally-Correct Writing:
  • One of Dr. Doofenshmirtz's earliest inventions, the Magnetism Magnifier, uses a specially-crafted funnel to gather a magnet's magnetic field, extending and directing it over long distances. Though greatly exaggerated in the show, this method of preserving a magnetic field's power was discovered to be completely accurate several years later, by physicists who used a tube made of superconducting and ferromagnetic materials to pull off the same trick. Lasers that create powerful magnetic fields would also become a thing years after the show's conclusion.
  • The episode "Day of the Living Gelatin" has the boys make gelatin inside a swimming pool to bounce and play on. As demonstrated in this video by Mark Rober, it's indeed possible to make a pool full of gelatin to lay on and to slide on, but it can't be used as a trampoline like in the episode and it won't really taste good. Not that the gelatin in the episode tastes any better, what with curry powder mixing into the sugary fruit flavors and all.
  • A running gag in the show whenever it involves a vehicle, the boys use an RC remote control in order to drive it legally. In real life, there are RC cars, trucks, and other vehicles, mainly used for theme parks. Children using them legally is a whole other story.
• Accidentally Correct Zoology: Regarding Perry the Platypus:
  • That chattering sound Perry makes? Platypi really do make those noises in real life (though of course not with their teeth, which they don't have). Interviews have indicated that neither the show's creators nor Perry's voice actor were aware of this during production.
  • Perry was designed with teal-green coloration simply due to Rule of Cool, but a study published in 2020 showed that real platypuses can indeed look green, at least under ultraviolet light. Dan Povenmire has commented on this.
• Acting for Two:
  • Linda and her mother, Betty Jo, are both voiced by Caroline Rhea.
  • Isabella and Jenny (one of Candace's friends) are both voiced by Alyson Stoner. She uses a variant of her natural voice for Jenny and pitches up her voice for Isabella.
  • The titular duo have the same voice actors in the Icelandic (all seasons) and Russian (seasons 2–4) dubs.
  • In the French dub, Buford and Jeremy are both voiced by Charles Pestel.
• Actor-Shared Background: Ferb's side of the family being British is an allusion to his voice actor being British.
• Adored by the Network: Good gravy! During the time it's been running, it has had the full backing of Disney and there isn't a day that it's not airing. It has never left Disney XD in its now-decade since the rebrand, years since ending. Throw in the Milo Murphy's Law crossover and the greenlighting of both a second original movie, and an extra two seasons, the adoration may never go away.
• Ascended Fanon:
  • It was a popular fanon theory that Ginger, the Asian Fireside Girl, was Stacy's little sister (probably due to there not being too many other Asian people in Danville). The season 4 premiere "For Your Ice Only" officially made this the case.
  • Jenny and Django are also confirmed to be siblings.
• Banned Episode: From 2009 to 2015, "Ready for the Bettys" was rarely if ever shown in reruns due to legal issues with a real life band called The Bettys which the writers did not know about at the time. This issue also caused "The Flying Fishmonger" (which was paired with it for syndication) and "Phineas and Ferb Musical Cliptastic Countdown" (which features the song "Ready for the Bettys") to be pulled as well. All of those episodes were finally aired again in the United States on the Disney Channel on May 22, 2015, and the episodes are still available on services such as iTunes, Netflix, and Disney+.
• The Cast Showoff:
  • Seemingly every post-"Busted" Vanessa sighting has resulted in her character gaining a song, apparently due to Disney realizing voice actress Olivia Olson has an excellent voice. She does the singing for a lot of other female characters as well— for instance, she provides Linda's singing voice in "I'm Lindana and I Wanna Have Fun", she provides the singing voices for The Bettys in "Ready for the Bettys", and in "The Monster of Phineas-n-Ferbenstein", she voices the backup singers. AND according to her Wikipedia page, she's also written songs for the show.
    
    She also gets songs in several episodes in which Vanessa doesn't physically appear, such as the Christmas Episode. (The songs tend to be "no one's actually singing, just accompanying a montage" songs.) In addition, there are episodes where she does appear (e.g.: the Star Wars crossover) just for the sake of singing songs rather than to advance the plot. It helps of course that her father (Martin Olson) is one of the show's writers and does some of the music for it as well.
  • Vincent Martella (Phineas) and Ashley Tisdale (Candace) get their share of time in the musical sun as well, though of course, they are the main (regularly speaking) characters.
  • Let us not forget Alyson Stoner. Interestingly, at first it didn't look like this trope was going to come into effect for Alyson, since initially every song Isabella was involved in either kept her in the background or replaced her voice as a gag (i.e. "S'Winter"). However, as of the Christmas special she's been getting some really nice numbers and even sings the main part on two recent ones, and that's not even counting her rendition of "Let it Snow" from the Christmas album.
  • Carl's voice actor, Tyler Mann, is a talented singer, but he didn't get to show off his chops until "Where's Perry?" This is lampshaded by Major Monogram who states "You may have some cleverly hidden singing chops."
  • Ariel Winter was initially cast as Fireside Girl Gretchen based on her work on Modern Family. It wasn't until "Night of the Living Pharmacists" that Winter finally got to show off her excellent singing voice, which she previously got to showcase on Sofia the First.
• Cast the Runner-Up: Mitchel Musso was originally hired to voice Ferb. When the creators decided to make him British instead, Musso was recast as Jeremy, whom they had previously planned to be The Ghost.
• Channel Hop: Sort of. From the second season onward, some new episodes premiere first on Disney XD as opposed to Disney Channel since the show skews more towards the former's demographic, and are then shown a week or so later on DC branded as "all new".
  • Well, sometimes a week or two. Sometimes six freakin' months.
  • As of "The Wizard of Odd", new episodes premiere on Disney Channel first again, but now they're labeled brand new when they premiere on Disney XD. In the middle of the fourth season, they' be premiering on Disney XD again and aired on Disney Channel as part of an "Disney XD on Disney Channel" block.
  • The upcoming revival announced in 2023 will have the two new seasons premiere on Disney+.
• Children Voicing Children: Vincent Martella and Thomas Brodie-Sangster were 14 and 17 respectively when they started voicing Phineas and Ferb. As the series progresses, Phineas' voice deepened after the first few episodes.
• Creator Backlash: Dan Povernmire's least favorite episode is "Boyfriend from 27,000 BC", feeling it felt flat, had a lack of good jokes, and no song.
• Cross-Dressing Voices:
  • Allergic Candace in "Jerk De Soleil" is voiced by Dan Povenmire, one of the show's creators and the voice of Dr. Doofenshmirtz. Same applies in foreign dubs, such as in Japanese version where her allergic voice is provided by Taketora, aka Akuma.
  • Also, the singing voices of female characters during a few songs are sometimes done by men (usually either Danny Jacob or his son, Aaron Daniel Jacob).
  • In the Croatian, Serbian, Hebrew, Turkish and first Persian dubs, Phineas is voiced by a female.
  • In the French dub, Baljeet is voiced by Nathalie Bienaimé while in the Polish dub, he's voiced by Anna Apostolakis-Gluzińska.
• Cut Song:
  • The Christmas Episode had a song for Buford called "The Elf Police", and a number for Candace called "What Does He Want", though the latter was returned for the extended version.
  • "Princess" was written as a love song from Jeremy to Candace in "Make Play", the episode in which Candace meets an Identical Stranger Princess of Drusselstein. In songwriter Jon Colton Barry's own words, "It was decided Jeremy shouldn't have feelings for someone who isn't Candace even if she really IS Candace pretending NOT to be Candace. Do you understand? Me neither. Thus the song was chucked. Oh well. It was a cute idea".
  • "This Is Your Backstory", written for the episode of the same name.
  • "Where the Heck Were We?", written for "Rollercoaster: The Musical" to be sung by Lawrence, Baljeet, Buford, and Irving, discussing their absent status in the premiere episode.
  • "Summer Belongs To You!" — Buford would have expressed his nay-saying in "You're Wrong", which would have been followed by a "This Is Our Inspirational Song", a more tongue-in-cheek precursor to "I Believe We Can". Both can be found here. They also planned to include "The Ballad of Klimpaloon", which was eventually heard in "The Klimpaloon Ultimatum".
  • In the Made-for-TV Movie, Candace and Stacy would have sung "Mysterious Force".
• The Danza:
  • In his first appearance in "Dude We're Getting The Band Back Together", Johnny was voiced by John DiMaggio.
  • "Picture This" introduces Baljeet's uncle Maulik, named after Baljeet's voice actor Maulik Pancholy.
• Dawson Casting: The main group of kids have ages 15 or under, according to the creators (with Candace being 15). None of their voice actors have ages falling into that range except Phineas' and Isabella's respective actors, Vincent Martella and Alyson Stoner, who were both 14 when the show first started. One of them, Maulik Pancholy, voice of Baljeet, was already in his late thirties (Pancholy was born in 1974). Incredibly, he's not even the oldest - the winner of that particular honor is Kelly Hu, who was 39 when she began voicing Stacy (Hu was born in 1968)!
  • Jeremy and Vanessa were roughly the same age as their voice actors, Mitchel Musso and Olivia Olson, respectively, during the casting. Even so, however, both Musso (b. 1991) and Olsen (b. 1992) are actually younger than Thomas Sangster (b. 1990), the voice of Ferb, a preteen.
    • Speaking of Ferb, his replacement voice actor, David Errigo Jr., is even older than Sangster, having been born in 1986, making him just a year younger than Ashley Tisdale, the voice of Candace!
• Descended Creator:
  • Creators Dan Povenmire and Jeff "Swampy" Marsh both voice the major characters of the show's recurring B plot; Heinz Doofenshirtz and Major Monogram, respectively.
  • Writer Aliki Theofilopoulos voiced the semi-recurring character of Mandy, the older sister of Thaddeus and Thor.
  • Writer Bobby Gaylor voices Buford van Stomm as well as radio host Stanky Dog.
  • Writer J.G. Orrantia voiced the recurring rival of Doofenshmirtz, Rodney von Roddenstein.
• Direct to Video:
  • "One Good Scare Ought to Do It!" made its US debut on the DVD The Fast and the Phineas, over two months before its US TV premiere on Disney Channel.
  • "Unfair Science Fair" and "Unfair Science Fair Redux" (Another Story) made their US debut on the DVD The Daze of Summer, around a week before their US TV premieres on Disney XD.
  • "The Doof Side of the Moon" made its US debut on the DVD A Very Perry Christmas, three days before its US TV premiere on Disney Channel.
  • "Doof 101" and "Tales From The Resistance" made their US debut on the "Phineas And Ferb Star Wars" DVD, approximately two weeks before their US TV premiere on Disney XD.
• Dueling Shows: This article says that Disney wants it to be the new SpongeBob. While the show has had a lot of success, it still has a long way to go to reach SpongeBob's level.
  • There was a friendly jab to SpongeBob in "Summer Belongs to You" with Phineas picking up a sponge and a starfish.
  • Note: Fans tend to overlook that Dan Povenmire wrote some of older SpongeBob episodes and wrote the iconic "Campfire Song Song." So the aforementioned jab to SpongeBob was also good-natured ribbing of his own work.
  • Also around this time, Cartoon Network was airing their own show featuring gadget inventing siblings who also have a bratty sibling.
• DVD Commentary: "Attack of the 50 Foot Sister" and "The Chronicles of Meap: More Than Meaps the Eye" each have two: a standard one by Jeff "Swampy" Marsh, Dan Povenmire and Jon Colton Barry, and an in-character one by Dr. Doofenshmirtz and Major Monogram. The former episode's commentaries are on the DVD The Movie: Across the 2nd Dimension, while the latter episode's commentaries are on the DVD A Very Perry Christmas: Bonus Disc.
  • Some time during the fourth season, Disney released an iTunes collection called "104 Days of Summer", that included the first 104 episodes, with two bonus commentary episodes with Mystery Science Theater 3000-style character commentaries: "No More Bunny Business" (Buford and Baljeet), "Flop Starz" (Doof and Norm), "Perry Lays an Egg" (Monogram and Carl), and "Ballad of Badbeard" (Linda, Candace, Stacy, Doof, Perry, Norm, Monogram and Carl). Unfortunately, the animation was done in Flash, so it is subpar, but the humor is on par with every other episode.
• Edited for Syndication: The Doofenshmirtz and Perry subplot to "Ain't No Kiddie Ride", where Doofenshmirtz attempted to burn his name into the ozone layer using aerosol spray cans, originally ended with Doofenshmirtz complaining about Perry catching him in his own trap. However, after the Consumer Aerosol Products Council complained that the episode was misleading (chlorofluorocarbons have been banned from aerosol products in the United States since 1978), the dialogue was changed so that Doofenshmirtz would discover - and point out - that the aerosol cans were completely harmless. The original ending was kept for the iTunes version, while Disney+ has the edited version.
• Executive Meddling: One of the best positive examples of this trope. The producers of the show asked to have a musical number in every episode after hearing the song "Gitchee Gitchee Goo" in the episode "Flop Starz". That idea could have failed hard, but it worked wondrously. So far, many of them have been really catchy and memorable.
  • Isabella and Baljeet did not exist in the original concept for the show, and were added at the request of the executives. Like with the musicals, this proved to be successful as both characters are very popular with the show's fans.
  • One executive suggested that Perry should get a girlfriend, only for the creators to say that they didn't want to go through with it because Perry's "married to his work." This was even made fun of in the episode "Nerds of a Feather".
  • Also notable is a Take That! in one episode aimed at Disney's Standards and Practices department. Phineas and Buford seem to be gearing up for a fight — only to have it revealed that they have to thumb wrestle when the referee finishes reading off the exact policy required by Standards and Practices.
• Executive Veto: In the episode "Act Your Age," the subplot is about Doofenshmirtz giving himself a Hollywood Mid-Life Crisis. One of the stereotypical things that he was going to do was "get a tattoo that he'll quickly regret." The creators got a note back basically saying "no Disney character will ever be shown in the act of getting a tattoo." Some time later, Maui was introduced.
• Fake Brit: Averted with Ferb's original voice actor, Thomas Brodie-Sangster. However, starting with the Milo Murphy's Law episode "The Phineas and Ferb Effect", Ferb's replacement voice actor, David Errigo, Jr., plays this straight, as he hails from New York.
• Follow the Leader: Because of this show, many animated Disney Channel shows have had at least one song in almost each episode, whether sung by characters or as commentary for what's happening on screen, including, but not limited to: Wander over Yonder, The Ghost and Molly McGee, Hailey's On It! and Moon Girl and Devil Dinosaur.
• Harpo Does Something Funny: A lot of Doofenshmirtz's lines, particularly his rants and ramblings, were improvised by Povenmire.
• Irony as She Is Cast:
  • While Baljeet has had numerous female Love Interests over the course of the show, his voice actor, Maulik Pancholy, came out as gay some time before the end of the show's run.
  • While there is a Running Gag of Isabella's not-so-subtle crush on Phineas, her voice actor, Alyson Stoner, came out as queer and non-binary in 2018.
• Keep Circulating the Tapes: The extended version of Phineas and Ferb Christmas Vacation! hasn't been made available to buy and can only be watched legally on television around Christmas. However, it is currently available on Disney+.
  • Doofenshmirtz's Daily Dirt, a web series featuring Dr. Doofenshmirtz talking about current trends, is no longer up on its original home on YouTube, meaning that most episodes can only be watched through reuploads (although some episodes are still up on Disney's website), with a few videos more still being missing.
  • Back then, many of the demos of the songs for the show were uploaded in the early 2010s and were later unlisted but still viewable for a long time. That was until YouTube made it so that all unlisted videos before 2017 would become private unless the owner makes them public or unlisted again. Since the channel had long been abandoned, all the demos are lost to time. While they did upload them also to Soundcloud, those too were removed later on. They have since been reuploaded onto YouTube as of March 2024.
• Kids' Meal Toy: The show had two kids' meal tie-ins from Subway:
  • The first one was released in 2008 and contained PVC figures of Phineas and Ferb, a race car based on the Season 1 episode, The Fast & The Phineas, and a launching rocket ship.
  • The second, released in 2013 for "Platypus Day", was a set of six reusable lunch bags.
• Live on Stage!: The show had a show called The Best LIVE Tour Ever!, a non-canon story about how the boys spend their final days of summer vacation. The show has caused some slight Memetic Mutation for the rather uncanny costumes.
• Long Runner: An interesting case due to Schedule Slip, though the series qualifies as one no matter what at least by typical Disney standards. If going strictly by season count, then Phineas and Ferb is still the longest-running series in Disney history with four seasons - but stuck in a multi-way tie in such with multiple other animated and live-action series. When going by the actual length of time elapsed between the premiere of the first and last episodes, it's far and away the longest-running Disney series running through eight years from 2007 to 2015 and multiple Channel Hops (from Toon Disney to switching variously with Disney XD and Disney Channel).
• Make-A-Wish Contribution: In "Phineas' Birthday Clip-o-Rama", Make-A-Wish kid Tabitha Comstock voices the girl at the party who says, "You're the best!" after everyone wishes Phineas a happy birthday.
• Marathon Running: In June 2015, Disney XD re-ran all the episodes of the show leading up to the Grand Finale.
• Meme Acknowledgement: Vincent Martella is quite aware of the memes about Phineas and the show, including Phineas being a Memetic Psychopath and the fetish fanart of Phineas being pregnant.
• Missing Episode: "Ready for the Bettys" was pulled from the broadcast rotation in the United States after a band from New York with the same name thought they were copying them, according to one of the writers of that episode. This caused the episode it was paired with, "The Flying Fishmonger", to be removed as well. The episodes are still available on Disney+, iTunes, and Amazon Instant. It was also available on Netflix until the show was removed from the service in 2018.
  • The full episode was aired again on Disney Channel on May 22, 2015 at 5:00am, and aired on Disney XD (for the first time) on June 10, during the marathon of every episode they aired in anticipation for the Series Finale.
  • For whatever reason, the Musical Cliptastic Countdown Hosted by Kelly Osbourne is not available on Disney+. It wasn't on Netflix either, yet it was available on Disney NOW.
• Non-Singing Voice: Ferb, as Danny Jacob, Dan Povenmire and Aaron Jacob have done his singing voice. Although, Thomas Brodie-Sangster did do his own singing in "The Ballad of Badbeard".
• The Other Darrin:
  • John DiMaggio voices Johnny in "Dude, We're Getting The Band Back Together". Starting from "Brain Drain" onward, he's voiced by Logan Miller.
  • In the Russian dub, both Phineas and Ferb had their voice actors replaced twice. Once for the second season, and once again for the third season and onwards. The differences between season 1 Phineas, then seasons 2 and 3 is very obvious. (Justified in a way: season one was dubbed in Moscow by SDI Sun Studio Russia, and the rest is done by Nevafilm, albeit in Moscow, too)".
  • Fireside Girl Holly was voiced by Cymphonique Miller from season 1 to the middle of season 2. After that, Diamond White would take over.
  • Fireside Girl Ginger (Stacy's sister) was voiced by Tiffany Espensen from season 1 to season 2. Michaela Zee would take over afterwards.
  • David Errigo Jr. has voiced Ferb ever since the Milo Murphy's Law episode "The Phineas and Ferb Effect", such as in the Disney+ film Candace Against the Universe, and will reportedly continue the role in season five. See also: Fake Brit.
  • For a Broken Karaoke short ("Ways to Be Anxious" parodying "Ways to Be Wicked" from Descendants 2), Candace was voiced by vocal impressionist Shelby Young.
  • In the Latin American dub:
    • Marco Portillo was the voice of Ferb. He was replaced by Diego Angeles in some episodes midway through the second season, before becoming his permanent replacement since the third season.
    • Mario Filio replaced Germán Fabregat as Dr. Heinz Doofenshmirtz in the Season 1 episodes "A Hard Day's Knight", "I, Brobot" and "One Good Scare Ought to Do It!".
• Out of Order:
  • The Amazon digital release breaks the four seasons into ten. The short seasons are mostly from the same full season, but in a completely random order (for instance the pilot is the eleventh episode). With the show's love of call backs and internal references this is very noticeable. The syndication order is slightly different than the production order, but nowhere near as blatant.
  • "Save Summer" was aired before "The Klimpaloon Ultimatum", as it mentions the latter.
  • "Split Personality" was aired after "Summer Belongs to You", as Candace mentions she's trying to make Jeremy her boyfriend in the former and they officially become a couple in the latter.
  • Almost the entire series, although still grouped by season, was not in airing order nor was it in production order on Disney+. Meanwhile, whereas Season 1 was in a completely random order, the other three seasons were in almost the exact same order Netflix used to have. This was fixed in July of 2020, when the episodes were finally put in production order.
• Pet Fad Starter: Notably averted. Dan Povenmire and Jeff "Swampy" Marsh were apparently aware of this trope when they developed the series, which is why they deliberately gave their protagonists a pet that was uncommon, an animal that kids could not "pick out at a pet store and beg [their parents] for", hence Perry being a Platypus.
• Playing Against Type:
  • Mrs. Johnson is pretty much the opposite of the type of character Jane Lynch normally plays.
  • Clancy Brown as Santa Claus.
  • Malcolm McDowell (A Clockwork Orange) as sweet old Grandpa Fletcher.
• Promoted Fangirl: Ashley Simpson (KicsterAsh on DeviantArt) is an artist who often makes fanarts of cartoons, Phineas and Ferb being one of them. One of the things she's known for is her designs of the cast, grown up well into their late teens and adults (an example). Eventually, this caught the attention of Dan Povenmire himself, who hired Simpson to design the characters for the episode "Act Your Age". She's credited as character designer for that episode, and later continued to work with Povenmire and Marsh as a storyboard artist on Milo Murphy's Law, and a storyboard revisionist in Candace Against the Universe.
• Real-Life Relative:
  • Starting in Season 3, Ginger has been voiced by Michaela Zee, the daughter of Ming-Na Wen, who voices Dr. Hirano.
  • Some of the songs are sung by Aaron Daniel Jacob, who is the son of series composer and also occasional singer Danny Jacob.
  • The recurring character of the Farmer's Wife is played by Jennifer L. Hughes, who is the wife of animation director Robert F. Hughes.
  • Polish dub: Phineas and Baljeet/Charlene are voiced by son and mother Wit Apostolakis Gluzinski and Anna Apostolakis-Gluzińska.
• Recycled Script: "Rollercoaster" and "Rollercoaster: The Musical," obviously.
  • "A Hard Day's Knight" comes across as almost a remake of "Are You My Mummy?" with one stock adventure lit antagonist switched out for another.
• Saved from Development Hell:
  • Phineas and Ferb was first conceived in 1993, but lack of faith in the project and additional commitments from the show's creators (hoping to get their big break that way), delayed the show for more than 10 years as they pitched it to networks like Fox Kids, Cartoon Network, and Nickelodeon, who all rejected the pilot. It was then pitched to Disney Channel in 2006 and it finally premiered in 2007.
  • There was a movie announced in 2011, originally planned to be released in 2013 - later 2014, but was inexplicably removed from Disney's release schedule. But on April 11, 2019, it was announced the movie would be produced and distributed on Disney+.
• Schedule Slip: The show officially has four seasons - which have been stretched across eight years from 2007 to 2015. Going strictly by season count, it's in a multi-way tie with a number of other animated and live-action shows for longest running Disney series, but going by calendar year run it takes the prize by an almost insurmountable margin.
• Screwed by the Network: Despite the exact opposite. Phineas and Ferb are subject to frequent marathons and specials across both of Disney's major channels, and they play a big part in a lot of the channel bumpers and advertising, but during the middle of Season 2 new episodes were subject to some severe Schedule Slip, to the point where they would air in other countries months before the US premieres, which are about a month apart from each other themselves. The premieres have since been getting more regular since the start of Season 3.
• Short Run in Peru:
  • The episode "Wizard of Odd", aired in Australia first, long before it aired in the US.
  • The episode "The Secret to Success" was first aired in Latin America, The UK, and Russia.
  • "We Call It Maze", "Ladies and Gentlemen, He is Max Modem", "Split Personality", and "Brain Drain" all aired in Latin America before the US. The former also aired in Taiwan and Brazil.
  • A handful of episodes like "Minor Monogram" and "Perry the Actorpus" aired on a Chilean television station before they aired in America.
  • For some reason, a few episodes of the 3rd season aired 1st in Philippine terrestrial TV- dubbed in Filipino.
  • Several later Season 4 episodes surfaced in Ukraine first. "Act Your Age" premiered in New Zealand first, against the wishes of the show's creators.
• Shrug of God: The creators, when asked Phineas and Ferb's age; though the original pitch was to make them nine-year olds (which certain early merchandise included in descriptions). This was retracted so that now they're merely "less than fifteen".
  • In "Quantum Boogaloo", however, they had to pick an age, so ten was given, as twenty years in the future. Future Linda says that the boys are thirty years old. However, she may have been rounding; Word of God was that fans shouldn't necessarily take her literally.
  • "Act Your Age" takes place 10 years after the primary setting of the show, and Phineas and Isabella are getting ready to go off to college. This greatly suggests that they are only around 8-10 years old.
• So My Kids Can Watch: Diedrich Bader (the voice of Albert) remarked at a Comic-Con panel he was hosting for the show that his son was extremely excited that he was gonna be a character in the series despite also being the voice of Batman.
• What Could Have Been: Has its own page
• Word of Gay: On TikTok, Dan Povenmire has confirmed◊ that Perry the Platypus is asexual.
• Word of God: "Ferb" is short for "Ferbs".
• Word of Saint Paul:
  • Long before Candace and Jeremy were an established couple, during interviews promoting the pilot, Jeremy's voice actor commented that Jeremy liked Candace back. Of course, it really wasn't all that hard to figure out, but still.
  • Caroline Rhea (Linda's voice actress) has stated via a tweet that she personally felt Linda knew Phineas and Ferb were building stuff the whole time.
• Write Who You Know:
  • Ferb is based on two different people known by the show's creators - a friend of theirs with the same name who was very good with tools, and an uncle of Jeff who rarely said much but always made profound statements.
  • The idea of Phineas and Ferb being step-brothers was partially^note other factors included wanting to make them the same age but not twins and a desire to give more representation of reconstituted families on kids' TV inspired by the fact that Jeff "Swampy" Marsh himself came from a reconstituted family. In fact, Jeff has gone on record saying that Lawrence is very similar to his own stepfather.
  • The references to Britain are based on the time that Marsh spent living in England. The various references to the Dutch sprinkled throughout are based on the fact that Marsh's wife is from the Netherlands.
