Phineas Flynn (voiced by Vincent Martella) Like other characters, he has red hair. His age is not mentioned. Phineas, along with his stepbrother Ferb Fletcher, star in the A-Plot of every episode. The series concerns Phineas's attempts to avoid boredom by finding something new to do every day of the summer vacation. He does this with his less-talkative stepbrother Ferb, and often with many other neighborhood children. He is known to be very selfless and energetic. Phineas has many catch phrases like "Oh, there you are, Perry" or "Hey, Ferb! I know what we're going to do today!" and "Hey, where's Perry?".
Phineas comes from a blended family. The creators chose this arrangement because they considered it underused in children's programming as well as from Marsh's experiences in one. As a character, Phineas has received a positive critical response, with one reviewer describing him and his brother as a "comical pairing." Phineas appears in Phineas and Ferb merchandise, including plush toys, t-shirts, and a video game.
Ferbs "Ferb" Fletcher
Ferb Fletcher (voiced by Thomas Sangster) is a boy of few words, Phineas's green-haired, intelligent but laconic stepbrother from the United Kingdom and created by Phineas and Ferb co-founders Dan Povenmire and Jeff "Swampy" Marsh. He first appeared in the show's pilot episode, "Rollercoaster."
Ferb and his stepbrother Phineas Flynn spend their days during their summer vacation having fun. They are featured in every episode's A-Plot constructing large scale inventions or taking part in other outlandish activities. Ferb, an engineering genius, allows Phineas to do most of the talking for the pair and is described as "more of a man of action," by Phineas, which makes him more of a plot device than a developed character. Ferb is more likely to sing than speak, but most often has a one-liner in the episodes. Ferb is named after a friend of the show's creators who was an expert on tools and, at times, stayed rather silent.
Candace Flynn (voiced by Ashley Tisdale) is Phineas's fifteen-year-old older sister and Ferb's stepsister. She first appeared in the pilot episode. Candace does not approve of the inventions her brothers create then she hates their creations, and in most episodes she attempts to "bust her brothers" by showing their mom. Her best friend is Stacy Hirano; Candace also has an obvious crush on Jeremy Johnson, but for a long time she was oblivious to the fact he liked her back. As a character, she has received a positive critical acclaim, having appeared in other media such as video games.
Perry the Platypus
Perry the Platypus (vocal effects by Dee Bradley Baker), a.k.a. Agent P, is Phineas and Ferb's pet platypus and first appeared along with a large portion of the main cast in the pilot episode "Rollercoaster." Perry is featured as the star of the B-Plot for all but one episode of the series alongside his arch-nemesis Dr. Heinz Doofenshmirtz. In the end, he pretends to destroy Phineas and Ferb's creations. He is a primarily silent character, with the only noises being the occasional rattling of his bill.
In Phineas and Ferb the Movie: Across the 2nd Dimension, an alternate reality (yet more evil and ruthless) version of Perry (known as Platyborg) appears. Platyborg would later return in the episode sequel, Tales from the Resistance: Back to the 2nd Dimension.
Dr. Heinz Doofenshmirtz (voiced by Dan Povenmire) is a mad scientist appearing in all but one episode's B-Plots thus far. He is the father to teenage Vanessa Doofenshmirtz and is the head of his own company, Doofenshmirtz Evil Inc. Depending on the episode, Dr. Doofenshmirtz's main goal is to either destroy or rule the Tri-State Area which was suggested to him as a starting point before trying to take over the world. Routinely bumbling, incompetent, and forgetful, almost all of Doofenshmirtz's plans—always involving various gadgets and inventions—have been thwarted by Perry the Platypus. However, a few of his schemes were quite successful, such as in the 2014 special Phineas and Ferb Save Summer when Doofenshmirtz moved the Earth away from its original orbit to bring on an early autumn, much to Perry's distress. After most defeats, he shouts his catchphrase, "Curse you, Perry the Platypus!"
His contraptions are almost all named "[something]-inator", and in "Unfair Science Fair" it is revealed that his first invention as a child was simply called "Inator".
Throughout the series, Doofenshmirtz's flashbacks (which are often shown after Perry has been captured) explore his mentally abusive and lonely childhood growing up in the fictional village Gimmelshtump, Druelselstein. Before becoming an evil scientist, Doofenshmirtz was a bratwurst vendor until being put out of business by the hot dog industry. Doofenshmirtz usually monologues and displays acts of cartoon-style physical violence towards his nemesis Perry, a skilled anthropomorphic platypus secret agent. His last name is frequently abbreviated to "Doof". Doofenshmirtz appears in several merchandise pieces, particularly the book series, and the video game.
In the 2011 TV film, Phineas and Ferb the Movie: Across the 2nd Dimension, an alternate reality (yet more intelligent and successful) version of Dr. Doofenshmirtz appears, with the regular Doctor Doofenshmirtz serving as a supporting character. 2nd Doofenshmirtz later returns in the episode sequel, Tales from the Resistance: Back to the 2nd Dimension.
Baljeet Tjinder (voiced by Maulik Pancholy) is Phineas' and Ferb's friend and neighbor. He wears blue overalls, despite being in grade school. A shy, intellectual, and polite boy who moved to Danville from India, he often helps the boys with their ideas and displays his knowledge of algebra and trivia. He also has a compulsive need to get good grades.
Carl the Intern
Carl the Intern (Tyler Alexander Mann) is Major Monogram's young unpaid intern of the O.W.C.A. (Organization Without a Cool Acronym) in charge of video taping Monogram when he is being interviewed and talking to Agent P. He is a bit careless, wears glasses, and sometimes forgets to focus the camera correctly.
The Fireside Girls are a group of ten girl scout-like girls led by Isabella in troop 46231. Isabella and the other Fireside Girls usually help Phineas and Ferb in their projects which, in turn, are at times created to help the Fireside Girls with a humanitarian cause.
Other members of the troop:
- Gretchen (voiced by Ariel Winter) wears glasses and has short auburn hair. She is second in command in the troop and the first (besides Isabella) who had been addressed by name.
- Holly (voiced by Cymphonique Miller (seasons 1-2), Diamond White (season 2-4), Dana Davis (as a teenager in "Act Your Age"))
- Katie (voiced by Isabella Acres, Soleil McGhee (as a teenager in "Act Your Age"))
- Milly (voiced by Isabella Murad, Dannah Phirman (as a teenager in "Act Your Age"))
- Adyson Sweetwater (voiced by Madison Pettis) The second member of the troop to be addressed by name, and the first to have been given a last name as well.
- Ginger Hirano (voiced by Tiffany Espensen (seasons 1-2), Michaela Zee (season 3-4), Ming-Na (as a teenager in "Act Your Age")) The younger sister of Candace's best friend Stacy. She has a crush on Baljeet.
Lawrence Fletcher (voiced by Richard O'Brien) is the father of Ferb and stepfather of Phineas and Candace. Lawrence sells antiques, is from the United Kingdom and is portrayed like a sitcom dad as being scatterbrained and unaware of what is going on. He often agrees to follow Phineas's instructions and even forces Candace to cooperate as if he considers Phineas and Ferb's skills normal. Unlike the boys' mother, he has seen some of the boys' inventions; he has not reacted negatively, and apparently believes that their mother approves. His precise surname is a matter of some dispute; in at least one episode, Isabella addresses him as "Mr. Flynn". Jeff "Swampy" Marsh has said that Lawrence Fletcher is very similar to his stepfather, Bill.
Linda Flynn-Fletcher (voiced by Caroline Rhea) is the mother of Phineas and Candace and stepmother of Ferb. Unaware of the large-scale projects that Phineas and Ferb create on a daily basis, Candace often drags her away from other interests in an attempt to get the boys in trouble. Each creation is somehow destroyed or eliminated moments before "Mom" arrives, leaving Candace dumbfounded and Linda reluctant to believe Candace. Linda was also a one-hit wonder known as "Lindana" with her song, "I'm Lindana and I Wanna Have Fun". That fact possibly makes her, as a singer, a parody of Cyndi Lauper, because of Lauper's hit Girls Just Want to Have Fun, and because both of them were famous singers in the 1980s (Linda fictionally). Her single is used as elevator music throughout the series. Her surname is not consistent throughout the series; in at least one episode, Candace refers to her as "Linda Flynn". She is based on Dan Povenmire's sister, also named Linda. She also used to date Dr. Doofenshmirtz during their mid-teens and that she was the one who inspired him to take over the Tri-State Area as a starting point for worldwide domination when he sarcastically stated that he would rule the world.
Isabella Garcia-Shapiro (voiced by Alyson Stoner) is a Jewish Mexican girl. She is one of the brothers' best friends and has an obvious crush on Phineas Flynn of which he is unaware, though he has shown he cares for her from time to time. She is known for the catchphrase, "Whatcha doin'?" and is the leader of the Fireside Girls troop 46231. The troop often helps Phineas and Ferb in their projects. She is named after series creator Dan Povenmire's oldest daughter.
Stacy Hirano (voiced by Kelly Hu) is Candace's best friend. She is of Japanese heritage. Stacy is shown to be annoyed by Candace's constant attempts to bust Phineas and Ferb, and would prefer to just have fun with the inventions; she also occasionally gets annoyed with Candace's gushing about her relationship with Jeremy. During the episode "Happy Birthday, Isabella", she finds out about Perry's secret Identity but doesn't lose her memories afterwards.
Jeremy Johnson (voiced by Mitchel Musso) is Candace Flynn's crush and later boyfriend. His age is sixteen, a year older than Candace. He works at Mr. Slushy Burger (sometimes named Mr. Slushy Dawg). In "Summer Belongs to You," it was confirmed that he and Candace had become boyfriend and girlfriend; toward the end of the episode, they kissed. He also has a band called "The Incidentals."
Major Francis Monogram (voiced by Jeff "Swampy" Marsh) is one of the heads of the O.W.C.A. (Organization Without a Cool Acronym) Department and Perry the Platypus' boss. He usually appears in a Nehru jacket on a giant screen giving Perry instructions for his next mission to stop Dr. Heinz Doofenshmirtz's endless attempts to take over the Tri-State Area. His uniform prominently features the initials "MM." He has a monobrow and wears a toupée. Sometimes, he is shown to have a lack of details about what Doofenshmirtz is up to, and orders Perry to go stop it as usual. Just like Doofenshmirtz, he has appeared in every episode of the series to date except, "Isabella and the Temple of Sap."
Buford van Stomm
Buford van Stomm (voiced by Bobby Gaylor) is frequently referred to as a bully, but he rarely hurts anyone on-screen. He is portrayed as a nice person with a tough guy attitude more often than as a bully. Phineas believes that Buford only bullies out of boredom thus Phineas often invites him to keep his mind occupied. He is thought not to get along with Baljeet, but in most episodes it is shown that they share a friendly bond. In one episode, Buford and Baljeet sing a song where they describe each other as "Frenemies" and "my least favorite brother".
Vanessa Doofenshmirtz (voiced by Olivia Olson) is Heinz and Charlene Doofenshmirtz's teenage daughter. She is sarcastic, mild-mannered, cynical, and dresses in a goth style. Vanessa is aware that her father is an evil scientist and knows about her father's nemesis Perry the Platypus. She is often exasperated by her father whenever he tries to establish a "father-daughter" bond between them as he doesn't really understand her interests or refuses to acknowledge that she is growing up and often assumes that she is also interested in "evil." She often tries to convince her mom that her dad is an "evil scientist" but, much like Candace, ultimately always fails when she does appear trying to catch him in the act, much to her dismay. She does, however, occasionally show appreciation for what he does for her, as he is clearly devoted to her (he once taught her how to drive and traveled halfway around the world after she got lost). Also, despite denying it so many times, Vanessa admits that she may be a little evil, as she once helped her father escape from custody by posing her hairdryer as a pistol to fool Major Monogram and Perry into releasing Doofenshmirtz, as shown in the special Phineas and Ferb: Summer Belongs to You!. Although Ferb has a crush on her, she remains oblivious to his affections as she already had a punk (not visigoth) boyfriend named "Johnny.", whom she later broke up with in the episode "Minor Monogram". She is in a relationship with Monty Monogram, the son of Major Monogram; however "Act Your Age" depicts her becoming involved with Ferb ten years down the line.
In addition to this, Vanessa makes a cameo appearance in the 2011 TV film, "Phineas and Ferb: Across the 2nd Dimension", along with an alternative reality version of herself (2nd Vanessa), though their scenes were deleted. 2nd Vanessa returned in the episode sequel, Tales from the Resistance: Back to the 2nd Dimension.
Vivian Garcia-Shapiro (voiced by Eileen Galindo), or simply "Viv," is Isabella's mother and lives across the street from Phineas and Ferb. She is a Jewish Mexican, one of Linda's best friends, and plays upright bass in a jazz band with Linda Flynn and Jeremy's mom. She is known for talking very fast and often making useless comments such as, "Oh, Candace, look how tall you've gotten." despite seeing Candace only a week earlier.
Pinky (vocals by Dee Bradley Baker) is Isabella's pet chihuahua. Much like Perry the Platypus, Pinky also lives a double-life as a secret agent for the O.W.C.A. under the codename, "Agent Pinky" in a division run by a commander named Wanda, a.k.a. Admiral Acronym. Pinky's nemesis is Professor Poofenplotz. Although he does not like dog food, Pinky will eat just about anything–especially his favorite; grilled cheese sandwiches, and even inedible objects, having once swallowed Isabella's Fireside Girl sash. Pinky always shakes as an ongoing joke about the behavior of Chihuahuas. He first appeared in the episode, "Journey to the Center of Candace."
Norm (voiced by John Viener) is a giant robot man created by Dr. Doofenshmirtz to destroy Perry the Platypus. Introduced in "Greece Lightning," he is a giant robotic mild-mannered businessman who often says, "The enemy of platypus is man." Norm has appeared in other episodes. For instance, in the episode, "Traffic Cam Caper," Perry borrows Norm as a ride to steal the traffic cam disk, for it has evidence that Perry is a secret agent. He was once a part of the O.W.C.A. but was fired because he was not an animal. Later in the series, he is depicted as Doofenshmirtz's sidekick and servant who makes frequent mistakes such as cooking eggs with the shells on or serving Doof chocolate cake for breakfast, though always staying cheery. In the episode "A Real Boy", Norm reveals that he has always wanted to be a human boy and considers Doofenshmirtz his father and Vanessa his sister.
In the 2011 TV film, Phineas and Ferb the Movie: Across the 2nd Dimension, a group of alternate reality (yet more menacing and successful) versions of Norm (known as Norm-Bots) appear, with the regular Norm making a cameo.
Charlene Doofenshmirtz (voiced by Allison Janney) is the former wife of Dr. Heinz Doofenshmirtz and shares custody of their daughter, Vanessa. Unaware of Dr. Doofenshmirtz's "evil" side, and in fact saying she does not believe someone can ever be truly evil, she divorced him due to a lack of common interests and having different life-goals. She is very wealthy and gives her ex-husband a large allowance each month. She is sometimes called by Vanessa who tries to "bust" her father but to no avail. Charlene and Linda Flynn-Fletcher have been paired up in a cooking class owned by Chef Pierre and in "I Scream, You Scream" were distracted by both Candace and Vanessa at the same time. Despite being divorced with Doof, she still goes to Doofenshmirtz family reunions claiming that she "kept the name," as seen in "Thaddeus and Thor."
However, in the episode "Tales From the Resistance: Back to the 2nd Dimension" (the episode sequel to the 2011 TV film, "Phineas and Ferb: Across the 2nd Dimension"), it is shown that there is an alternate reality version of Charlene Doofenshmirtz. It turns out that 2nd Charlene is still married to 2nd Doof and actually shares much of his evil personality, and that their divorce was just a ruse to gain financial advantages during 2nd Doof's reign (such as receiving coupon mail, putting up junk yard sales, and going on separate vacation trips).
Suzy Johnson (voiced by Kari Wahlgren), known as Little Suzy Johnson, is Jeremy's little sister. She has a high-pitched squeaky voice and appears very sweet and innocent. However, she is actually very spoiled and manipulative and very possessive over Jeremy, once telling Candace, "There is only one girl in Jeremy's life" and thus will do anything to keep Candace away from her brother.
Grandpa Clyde and Grandma Betty Jo
Grandpa Clyde Flynn and Grandma Betty Jo Flynn (voiced by Barry Bostwick and Caroline Rhea respectively) are Linda's parents, Phineas and Candace's maternal grandparents, Lawrence's -in-laws, and Ferb's step-grandparents. Every summer, they invite the family along with many neighborhood kids to a lakehouse which Phineas calls, "Camp P&F". Though they are old, they often participate in the kids' capers. Grandpa Clyde, like Phineas and Ferb, has a great sense of mechanics, as seen in "Crack That Whip!" Betty Jo is also shown in the same episode to have a fierce rivalry with Edna Hildagard, Jeremy and Suzy's grandmother.
Grandpa Reginald and Grandma Winifred
Grandma Winifred Fletcher and Grandpa Reginald Fletcher (voiced by Malcolm McDowell and Jane Carr) are Lawrence's parents, Ferb's paternal grandparents, Phineas and Candace's step grandparents, and Linda Flynn Fletcher's in laws who reside in the United Kingdom. Reginald used to be a daredevil known as the Flying Fishmonger the anthem.
Roger Doofenshmirtz (voiced by John O'Hurley) is mayor of Danville and Dr. Heinz Doofenshmirtz's younger brother. Heinz often states angrily that Roger is their mother's favorite son. In "Tree to Get Ready" Roger states that he is, "the most handsome and charming man in the Tri-State area."
Irving Du Bois
Irving Du Bois (voiced by Jack McBrayer) is Phineas' and Ferb's self-proclaimed biggest fan. He always carries a scrapbook that he filled with images and souvenirs from Phineas and Ferb's big ideas as well as a strand of Ferb's hair. Irving has an older brother Albert, who is self-nicknamed 'The Truth Detector.'
Django Brown (voiced by Alec Holden) is a friend of Phineas and Ferb. Django is the son of the artist Beppo Brown from "Oil on Candace," who is famous for his work in making giant creations, from refrigerators to dental floss. He is named after co-creator's Jeff "Swampy" Marsh son, Django Marsh, who voices minor characters on the show.
Admiral Wanda Acronym (voiced by Jane Leeves) is the one of the heads of the O.W.C.A. (Organization Without a Cool Acronym) Department and Pinky the Chihuahua' boss. Just like Major Monogram, she usually appears on a giant screen giving Pinky instructions for his next mission to stop Professor Poofenplotz's endless attempts to take over the world.
Also, just like Monogram (who has an unpaid intern named Carl), Adrimal Acronym has her own unpaid intern named Carla, who bears some resemblances to Carl.
Carla (voiced by Jennifer Hale) is one of the interns working for the O.W.C.A.. She bears some resemblances to Carl (possible could be her brother or cousin), as her boss Admiral Acronym stated that she comes from an 'entire family of unpaid interns'. She usually gives in the intelligence of whatever plans that Poofenplotz is up to.
Professor Esmeralda Poofenplotz (voiced by Amanda Plummer) is an old mad scientist and the nemesis of Agent Pinky, Isabella's pet Chihuahua. She is known for her silly attempts for worldwide domination. Her known schemes so far involve replacing handbags, stealing royal jelly, and searching for strong hairspray (her favorite is "Stiff Beauty" hairspray, which originally was only used by clowns). Needless to say, because of her somewhat arrogant personality, Poofenplotz has failed to know about the flaws of her schemes. And because of that, it has allowed Pinky to defeat her in return, leaving an humiliated Poofenplotz to yell out, "Curse you, Pinky the Chihuahua!", similar to how Heinz Doofenshmirtz says whenever his plans get foiled by Perry the Platypus.
Love Händel is a rock band idolized by many in the Danville Tri-State Area, first seen the episode, "Dude, We're Gettin' the Band Back Together!" Lawrence Fletcher and Linda Flynn shared their first kiss at a Love Händel concert. Shortly afterward, plagued by infighting caused by the pressures of a dwindling fanbase, Love Händel split up. Lead Singer Danny (voiced by Jaret Reddick) became the owner of Danny's Music Shop. Bass Player Bobbi Fabulous (voiced by Carlos Alazraqui) became the owner of Bobbi's Fashion Salon and Linda's hairdresser. Sherman "Swampy" (voiced by Steve Zahn) ended up working at the Danville Public Library, believing he had lost his sense of rhythm. Eventually all three members are convinced to reunite for a concert in the Flynn/Fletcher's backyard, in which they sing their hit song, "You Snuck Your Way Right into My Heart." Love Handel occasionally reappears in other episodes and in the movie where they sing their songs.
Monty Monogram (voiced by Seth Green) is Major Monogram's son and has been working in O.W.C.A. since "Minor Monogram". Vanessa Doofenshmirtz seems to become interested in him after she broke up with Johnny, and it is possible that he is slightly interested in her too because he winks at her before leaving. They have coffee together in "Sipping with the Enemy", at which point they apparently begin to date one another. In "Minor Monogram" he has recently graduated from the "High School Without a Cool Acronym" (H.S.W.C.A.) and he really wants to fight evil following his dad's footsteps. Due to the rivalry between his father and Dr. Doofenshmirtz, he and Vanessa try to keep it secret from the two of them, aided by Perry and Carl (though the latter briefly blackmailed Monty in hopes of getting his help in earning Major Monogram's approval). In the special Phineas and Ferb Save Summer, Monty played a major role as he attempts to help rescue all of the captured agents and defeat the villains of L.O.V.E.M.U.F.F.I.N. in their plan to take over the world by sending it into a new Ice Age.
Dr. Hirano (voiced by Ming-Na Wen) is Stacy and Ginger's mother. She removed Isabella's tonsils in, "I Scream, You Scream." She is often referred to through conversations between Candace and Stacy where Candace gratifies, "Stacy, you're a genius!" and Stacy replies, "Could you call my mom and tell her that?"
Aloyse Everheart Elizabeth Otto Wolfgang Hypatia Gunther Galen Gary Cooper von Roddenstein (voiced by Joe Orrantia), or Rodney for short, is a bald evil scientist and a member of the villain organization L.O.V.E.M.U.F.F.I.N.. He serves as the main rival to Dr. Doofenshmirtz, believing him to a disappointment because of his constant failures. Throughout most of his appearances, Rodney attempts to best out on Doofenshmirtz to show that he's a better villain, only to fail so many times (either due to Doofenshmirtz's antics or Perry's intervention). Similar to Doofenshmirtz, Rodney usually makes his own inventions and ends them with the suffix '-inizor'. He also has his own robot apprentice named Chloe, whom Norm fell in love with. He also has a son named Orville, who usually helps him create his -inizors.
Rodney would later go on to appear in the 2014 episode special, "Phineas and Ferb Save Summer", where he learns that Doofenshmirtz has actually succeeded in moving the Earth away from the Sun to an early autumn with his latest -inator. Taking the opportunity to exploit this, Rodney leads L.O.V.E.M.U.F.F.I.N. into revealing themselves to the world and capturing all of O.W.C.A.'s agents. He even creates an -inizor (which is just ten times the size and strength of Doof's -inator) that will send the Earth into a new Ice Age if the world refuse to meet all of L.O.V.E.M.U.F.F.I.N.'s demands. However, in the end, Doofenshmirtz (who is completely disgusted by Rodney's true goal for worldwide domination) manages to defeat Rodney, who then gets arrested by Monty Monogram and taken into O.W.C.A. custody.
Professor Parenthesis (voiced by Paul Reubens) is an evil scientist serving in the 2015 standalone special, O.W.C.A. Files. He has claimed to have known Major Monogram during biology class 30 years ago (even announcing several names of their old classmates). In the special, Parenthesis plots to take over O.W.C.A. by using robotic fleas to take control of all of its animal agents, so that he can unleash them to wreak havoc around the world in order to smear O.W.C.A.'s good name. During the climax, he is revealed to be a tiny talking flea controlling a human android, as he plans to capture Perry (who is among the few agents not be infested with the robotic fleas) while finalizing his control over the agents to become permanent. However, Perry's team of trainees (including Doofenshmirtz, who has given up evil at that time) set up a trap against Parenthesis, destroy his robotic fleas to free the agents, and confine Parenthesis inside a pill bottle as punishment for his crimes.
There are several characters that reappear as recurring joke such as farmer and wife. The wife always tells her husband "I can't believe you (blank) without getting a (blank)" and then it falls from the sky and sometimes hits her. For example, in the episode, "Leave the Busting to Us", the wife says, "I can't believe you bought a bunny farm but forgot to buy any bunnies! Did you really think the bunnies would fall from the sky?" A pack of rabbits then falls from the sky and hits her. Then in the end credits scene from said episode, the wife yells at her husband, "I can't believe you sold our lucrative bunny farm and bought a van rental place! And you didn't buy a single van!" She hears a van falling over her and says, "Not one word," just before the van crashes and injures her (the screen blacks out the impact).
Another minor character is the Giant Floating Baby Head. In an interview, Dan Povenmire stated that the head had originated from a storyboard panel that writer Mike Diederich had drawn which director Rob Hughes found hilarious enough to create an entire bit around. It first appears in "One Good Scare Ought to Do It!" and has since appeared in several other episode. 
Dr. Doofenshmirtz's mother (Cloris Leachman) has appeared. She refers to Roger being her favorite child and often ignores Heinz. Albert (voiced by Diedrich Bader), Irving's Brother has appeared in "Not Phineas and Ferb", "The Doof Side of the Moon", and "Nerds of a Feather".
