- The soliloquy from The Princess Sensibilities Candace keeps trying to read brings to mind the famous "To Be or Not To Be" soliloquy from Hamlet.
- It's possible that the A plot's resolution was a shout out to Lilo & Stitch. To recap, Doof is holding an ice cream cone, Perry uses a whale whistle to summon a whale, which somehow leaps up into the air, over the two. The most notable thing that the whale hits is the top of the ice cream cone that Doofenshmirtz was holding, which falls through the air and, eventually, lands on Phineas's head. There's a recurring character in Lilo & Stitch who always loses his ice cream in a similar manner— once even having it knocked down by the tip of a spaceship's wing, which is the most like this scenario.

Lastly, a non-Jp reference happens at the end, when Candace is chased by the Rex in the museum, the Leitmotif of Grumpy the Tyrannosaurus from the original Land of the Lost is heard.
- When Perry is replaced by a panda named Peter the Panda, there's a song called "Missing My Nemesis" that sounds and has similar clips to "And She Loved Me" from Toy Story 2.

- Isabella's "I'm going to take that ball and shoot it into that goal" speech is based on Billy Jack's famous Badass Boast, right down to her assuring him "and there's nothing you're gonna be able to do about it."

- And the Sergeant has stepped right out of Full Metal Jacket.
- The TV interviewer greatly resembles Geraldo Rivera.
- The song that plays when Candace and Jeremy try to fly the Flying Car of the Future (Today) to the reform school sounds a bit like the theme from Back to the Future.

- It's possible that "the Ferbalistic Groovatron 9000" is a Shout-Out to the Future trilogy of Ratchet & Clank, which features a recurring device/weapon called the Groovitron. Coincidentally, the "Otherdimensionator" comes close to sharing a name with Tools of Destruction's Dimensionator.

- Also lampshaded:
- The title is a reference to Dirty Dancing.
What Do It Do?
- Phineas invokes the "Friends, Romans, Countrymen" to the group assembled in his yard: "Friends, Bullies, Irving".

Candace Gets Busted
The Great Indoors
- When Phineas and Ferb are showing off their biosphere to the Fireside girls, Phineas asks, "Can we cook, or can't we?", a Shout Out to Star Trek II: The Wrath of Khan, were Dr. Carol Marcus asks "Can I cook or can't I?" when showing Kirk the Genesis Cave.

- He also makes the same declaration as the villain from I, Robot: "My logic is infallible."
- Major Monogram has security footage of Dr. Doofenshmirtz singing a song about Shangri-La, which may be a reference to Xanadu (which featured a song of the same name sung by Olivia Newton-John and Electric Light Orchestra—the latter of whom, likely coincidentally, has a song called "Shangri-La").

- Candace's hair is a clear shout out to The Bride of Frankenstein.

- The use of "The Blue Danube" as background music.
- The wormhole sequence.
- And of course the entire ending scene with an old Sergei, and Ferb as the Star child.

- When the space station gets an "Asteroid Warning" on the computer displays, the asteroid on the display resembles one depicted in the arcade game "Asteroids".
- When Perry and Doofenshmirtz are fighting in the cab of Doofenzshmirtz's truck, the fight choreography is directly taken from Indy's fight with the driver of the German truck in Raiders of the Lost Ark.

- To drive this point home, Ferb's cousin (who isn't named after David Beckham), is named "Eliza".
- The preview for the episode features the return of "Doofenshmirtz is a Superstar", which includes Heinz running headfirst into a toilet. His cry of "It won't stop flushing!" might be a reference to the Super Toilet/"So much clogging!" gag from The Fairly OddParents!.
- There's also a literal shout out, right in line with the one from The Secret of Success. In the middle of the musical number, the L.O.V.E.M.U.F.F.I.N singers belt out "YES! WE! CAN!"
That's the Spirit
- You can hear a voice say, "I'm incorporeal. Isn't that scary?" in the haunted house. He's speaking in an impression of Vincent Price's narration of the Thriller music video.
- As is Russell's dad, Waylon's voice.
- Baljeet's costume looks an awful lot like the creature that Daffy Duck is turned into in one of the No Fourth Wall episodes of Looney Tunes ("Duck Amuck"). In the preview Buford even calls his costume a daffodil, despite looking nothing like one. Could be coincidence.
The Curse of Candace
- It begins with one of the greatest parodies of Twilight to date.JARED: "I expect this from your kind, Michael—football players, I mean—but Kristen, I mean, we were both—moody outcasts! We...we loved each other!"
- Later, after the movie ends, when Stacey and Candace exit the cinema hall, there is a poster revealing that the movie is called "Early Evening".
- This is also coupled with an Actor Allusion, as the person who voices the Jacob Black Expy in the movie is Michael J. Fox, who is known for another adolescent-oriented film that involves lycanthropes.
- In that same episode, though, you can see posters for such fictional blockbusters as Leap and New Zealand.
- We get this gem from Lawrence (played by Richard O'Brien): "Well, this isn't much of a horror movie. Where are the rock 'n roll musical numbers?"
Escape from Phineas Tower
- The tower after being shot by the rude-inator starts acting like Hal 9000 from 2001: A Space Odyssey.

- The most basic formula of Ferb Latin is identical to "pig latin". Phineas even describes it as "all the fun of Pig Latin, but safe for vegetarians to use".
- The Buford-potato hybrids act much like the Gremlins.
- Many of the characters come off this way, being cavepeople, but Buford in particular looks like he walked right off the set of The Flintstones.
- Easily missed among the cave talk, Doofendung refers to prehistoric Perry as "Bunka da bunkakwunk." In the TV special, The Cat in the Hat claims that he's "a bunka in a bunkakwunk, in Eskimo."
- The training montage song "Way of the Platypus" contains multiple nods to Mulan, and has this lyric:
- The giant robots are a shout out to Japan's love of giant mech series. This is lampshaded by Regent Monogram. It might be taken a step further, with Doof's dragon referencing Godzilla, or Kaiju in general, and the terracotta warrior referencing Super Sentai (five pilots controlling a single humanoid robot) or Ultraman (a humanoid robot who fights kaiju) but it's hard to say.
- The title and the mystical sword are references to the Arthurian legend Excalibur. The quest is given to them by the Lady of the Puddle, who mentioned the Lady of the Lake (the one who gave Arthur Excalibur) is her mother. Cuts to the Lady of the Lake who is in the middle of giving King Arthur Excaliber.
- There is a swamp in The Neverending Story. In order to cross it, you must not think unhappy thoughts. "This swamp was made for me, Ferb!"
- Among the ten thousand monsters gathered by Phineas and Ferb is a Gargoyle resembling a green Goliath.
- The episode is loaded with nods to fantasy stories like The Lord Of The Rings, The Never Ending Story, and The Princess Bride.
- Malefishmirtz's name and outfit is a nod to Maleficent from Disney's Sleeping Beauty.
- Strangely enough, the "Epic Monster Battle" song sounds a lot like Christian musician Carmen's "The Champion".
Phineas and Ferb and the Temple of Juatchadoon
- The episode takes many homages from the Indiana Jones movies, including the title referencing the Temple of Doom movie, Isabella betraying Phineas and Ferb like how Elsa betrayed Indy in Indiana Jones and the Last Crusade, and Doof lampshading when the temple is crumbling that his face will probably melt off.
Monster from the Id
- The title is a nod to Forbidden Planet. The opening of the episode has the kids sharing their minds; besides the obvious Star Trek mindmeld shoutout, the set-up also calls to mind Inception's dreamsharing. Near the end of that adventure, while inside Candace's mind, all the kids have to give Baljeet a 'kick', by shocking him with grammatically incorrect contractions. It also appears that Buford remained behind with Candace's primal self, in her mind's limbo. The music during this segment also bears strong similarities to Hans Zimmer's score for Inception, particularly the use of electric guitar.
- Doofenshmirtz gets the turkey from the Turkey-inator stuck on his head, and also is a callback to a The One with All the Thanksgivings as well.
The Remains of the Platypus
- The title may be a reference to The Remains of the Day.
- We get a song about Perry's hat as it floats on the wind. We briefly pass a man in a white suit whose sitting on a bench, waiting for the bus. I guess this show is like a box of chocolates; you never know what references you're going to get.
- After Perry eats Doofenshmirtz's cheese, his belly becomes cheese-shaped.
- The entire episode is basically a Phineas-and-Ferbified version of the movie Memento, not so much in terms of the plot, but in the way the story is told: it starts at almost the end, and works its way scene-by-scene back to how it all began, slowly revealing more of the plot as it goes. This might just be seen as an unintentional coincidence, except that at the end, Perry who is revealed to have had his memory stolen by Doofenshmirtz, finally remembers his mission because he had written a message to himself on his body before his memory was erased.
Mom's in the House
- The "Perrytronic" number is one big old nod to Gigantor and other old Humongous Mecha anime from The '60s.
Perry The Actorpus
- "Let's Spend Half a Day" is a new-wave 1980's song in the style of the Go-Gos, and the boys and Perry even recreate a few scenes from the music video for "Vacation".
- The B-plot involves a mad scientist using an experiment designed to cause chaos by exposing people's little white lies, which sounds suspiciously like the "Fibber" episode of Lilo & Stitch: The Series, another Disney cartoon.
Bully Bromance Breakup
Quietest Day Ever
The Doonkelberry Imperative
- This episode is one giant Take That! to American Politics: nothing can get done because everyone is arguing about whether things should go in the left or right direction.
- While retaking his driving test, Doofenshmirtz drives a Yugo.
Meapless in Seattle
- For another absolutely epic Star Wars reference, we are given the opening credits.
- In another Star Wars reference, Mitch's pod walker looks similar to an AT-ST, and is taken out by wrapping its legs, like an AT-AT in the Battle of Hoth.
- As Phineas, Ferb, Isabella, Candace, and Meap fly into Seattle, the scene is accompanied by a song reminiscent of "Smells Like Teenage Spirit." Fitting as Seattle was known for being a Grunge Rock hotspot from the mid-80's well into the 90's, as well as Seattle being Nirvana's home turf.
- As Meap makes a call to his home planet, one of the Meap intel officers enters a Kubricky War Room to inform the Meap General.
- Also, in a very generous piece of Parental Bonus, we get Candace referencing The Blair Witch Project when she leaves the last message to mom on her phone.
Delivery of Destiny
- Paul the delivery guy shifts his truck to "turbo," causing it to jump down the street like KITT's turbo boosts in Knight Rider.
- Buford parodies the famous line from Casablanca: "Of all the clearings in all the woods the world, she walks into mine."
The Mom Attractor
- The giant robotic Linda climbs Doof's building like King Kong.
- Perry's transit to his lair is an obvious reference to The Lion, the Witch, and the Wardrobe.
- Doof references The Duck Song ("And the duck says 'got any grapes?'") while on a coffee break with Agent P and the other agents. Needless to say, the duck is not amused.
- Rodrigo makes a We Can Rule Together offer to Vanessa similar to the one Darth Vader offers to Luke in The Empire Strikes Back.
What A Croc!
- Crickey the Crocodile is named for Steve Irwin's Catchphrase.
- Like Homer Simpson occasionally does, Candace gets into an argument with her inner voice.
Sci-Fi Pie Fly
- The pizzeria promises "Delivery in 37 minutes of it's free", a nod to the now-defunct Domino's gimmick.
- Additionally, the pizzeria is called Rocko's, referencing another show Dan and Swampy worked on.
Sipping with the Enemy
- The title is a reference to "Sleeping With the Enemy"
Tri-State Treasure: Boot of Secrets
- Phineas and Ferb's film ends with a Tyrannosaurus rex roaring while a banner falls down in front of the screen.
- The title is a reference to the second National Treasure film.
- The entire plot is a send up of Indiana Jones tropes. Most notably, the picking the right boot scrapper is based off the "cup of Christ" scene from The Last Crusade.
- FFC Regulations are brought up in the musical number: "IF you're watching at home there's a 7-second delay. This refers to the Television Delay rule set up by the FCC ever since the Super Bowl XXXVIII halftime show controversy.
- Perry and Platy!Doof's slow motion kung fu fight mirrors some action scenes from The Matrix.
When Worlds Collide
- The silhouette of Candace against the light, seen when the planet arrives on their backyard, is similar to a scene from Close Encounters of the Third Kind.
What'd I Miss?
- When Buford is questioned regarding him teaching squirrels to dance, he responds that "He's like an onion."Baljeet: Because you have layers?Buford: That too!
Road to Danville
- Doofenshmirtz is set to star in The Pizza Guy Cometh, a nod to The Iceman Cometh by Eugene O'Neil.
This Is Your Backstory
- The title, as well as the format of Doofenshmirtz's plot, refers to the old TV series This Is Your Life.
- Candace tells her dad to "Tear down this fence!", parodying Ronald Reagan's famous "Tear down this wall!" speech.
For Your Ice Only
- During the kids' ice show, the famous stage direction from A Winters Tale is recreated: "Exit, pursued by a bear."
- The kids' ice show of a dystopian world where everything is constantly exploding brings to mind Mad Max.
Happy New Year!
- About 40 seconds into the New Years song we cut to Phineas and Ferb doing the Gangnam Style dance.
- In fact, the kids to a number of famous dances throughout the song, including the Running Man, Stayin' Alive, and the Conga line.
Fly On the Wall
- When Fly!Candace is caught in her mother's car, she smacks against the back window wailing "Help Meeee!"
- Perry's trap is basically a giant game of Mousetrap.
My Sweet Ride
- Doofenshmirtz's flashback to the Gimmelshtump car show depicts lots of strange vehicles moving from right to left in single file.
- Doofenshmirtz's musical number has him in a white tux accompanied by a jazz band dancing in a way remarkably similar to Cab Calloway. Heck, the song might even be considered a reference to 'The Old Man of The Mountain", famously used in a Betty Boop cartoon of the same name.
- Doofenshmirtz suggests going to Niagara Falls. The scene then cuts to Him, Perry, Monogram, Carl, Lyla, and Peter the Panda at the railing to the falls while orchestral music plays before they each leave, passing by eleven men as they go.
- This has a clever Army of Darkness reference.
- May or may not be intentional, but the situation Perry and Doofenshmirtz get into (being handcuffed to each other and chased by a hunter) is extremely similar to the plot of one Danny Phantom episode. The hunter even mentions hanging them in his trophy room!
- Probably not a reference to Danny Phantom; that situation is common enough to have it's own trope name.
- May or may not be intentional, but the situation Perry and Doofenshmirtz get into (being handcuffed to each other and chased by a hunter) is extremely similar to the plot of one Danny Phantom episode. The hunter even mentions hanging them in his trophy room!
- While Perry and Doof are preparing to confront Liam, the music imitates the Predator theme.
- The episodes includes several references to The Shawshank Redemption, including the drainpipe escape and the prison including an inmate named Red who knows how to get things, with his narration done in the stye of Alice's Restaurant ..
- The basic plot is that the heroes are given the chance to vacation on an alien planet by swapping minds with its inhabitants, only to discover once the swap has taken place that they've been conned. This is very similar to the opening chapters of Robert Sheckley's 1966 novel Mindswap. In fact the phrase "mind swap" actually occurs in the episode.
Backyard Hodge Podge
- Linda is baking for the "Live and Let Pie" charity event.
- Phineas resembles Fabio in Isabella's fantasy.
Great Balls Of Water
- Title is a reference to a Jerry Lee Lewis song.

- When Perry and Pinky catch up to Dr. Doof, Doof: " Perry the Platypus!?"And your little dog, too?!"
Knot My Problem
- The set-up for the episode is that the kids want to recreate the legend of Alexander the Great and the Gordian knot.
- Buford quotes Curly Howard (of Three Stooges fame): "I'm a victim o' circumstance!"
- After the kids finish climbing their climbing-wall and are surrounded by stars and "getting light-headed".Buford: Oh I Get it. We are in space. AAAHAAAHAAAHAAA! I heard that.
- The song brings to mind Johnny Cash and his cowboy ballads, especially "Ghost Riders in the Sky".
Happy Birthday, Isabella

Love at First Byte

Terrifying Tri-State Trilogy of Terror
- The third story about getting grape juice on a platypus resembles the plot from Gremlins.
- When the first evil platypus clone escapes from the tent:
Face Your Fear
- The "meanwhile at the Hall of Justice" line from Super Friends is parodied at the Danville Space Laboratory (not Labrador).
- Doof's username is Heiz 58, because Heniz 57 is already taken.
Cheers for Fears
- Monogram mentions that he and his friends have an event called "Horrific Movie Night", where they watch and mock bad movies. Funny thing is that one of thr storyboard artists for the episode, John Mathot, has a similar thing called "Horrible Movie Night".
- The title is a reference to Tears for Fears.
- Much of this episode directly points to Ken Burns' documentary on the American Civil War: The closeup on the coin, the period music, and the narration, for instance.
Live and Let Drive
- With a title that's a reference to Live and Let Die, it's no surprise that the first half of the story seems to be an exercise in "how many James Bond references can we squeeze in 5 minutes": Perry drives an Olson Martin 1963, accompanied by a Suspiciously Similar Substitute of the Dr. No opening theme; Doofenshmirtz plays cards in a casino and tells a player who walked away in disgust at losing to never say never; a casino official who looks suspisciously like Oddjob tells Doof that no pets are allowed (Doof was holding a white cat); Norm found metal teeth in the lair Doof is currently staying where there's also still standing a rocket; and Doofenshmirtz' new jingle is a straight-up Bond Theme (with strong influences of the Goldfinger theme).
Lost in Danville
- The episode was written by Damien Lindelof, a co-creator of Lost, and features Terry O'Quinn as the voice of Professor Mystery and a polar bear that turns out to be Lawrence from another dimension.
The Klimpaloon Ultimatum
- An entire scene is devoted to a reference to the Leeroy Jenkins Video, with Phineas making a plan and Buford taking on the infamous role of Leeroy Jenkins.Phineas: Okay. (gets into the snow and maps out a diagram) I'll just create a diversion here so that Buford and Baljeet can flank them from the left. Ferb can then use his intimidating shout to scatter them so that Isabella can come in from behind. That should work unless they have reinforcements. What do you think, Baljeet? Can you give me a number crunch real quick?
Baljeet: Uh, gimme a sec. I am coming up with a 32.3% chance of success.
Phineas: Well, we've seen worse.
Buford: Alright, guys, let's do this! BUFORD VAN STOOOOOOOOOOOOOOMMMMMMMM!!!!!!

- Near the beginning, the music while Phineas, Ferb, and the gang are looking at the giant map is an exact quote of a song from Chicken Run.
- When Phineas gives Candace a rousing speech in Paris in "Summer Belongs to You" he paraphrases one of the most famous lines in Tengen Toppa Gurren Lagann,
- Phineas: ...Which means you believed in us.
Ferb: And we believe in you.
Phineas: And therefore, through the transitive property of belief, you do believe in yourself!
- And yet again, while in Paris and trying to get Phineas's attention, Isabella says, "We'll always have giant plastic baguels".
- Still again, an origami unicorn is used as a throwaway gag.
- The jumping robot at the beginning gets all René Descartes when it says "I jump, therefore I am". Bonus points are gained for when Phineas meantioned earlier that the robot gained self awareness.

- At one point, Major Monogram says "Cheese and crackers!", which may be a reference to Kim Possible.

- Given a certain other role of Alyson Stoner's and said role's hobby, could we have Actor Allusion going on here?

- When Phineas is trying to explain the concept behind their trip and Buford doesn't get it:Buford: "No, no; don't try to confuse me with your sorcerer's ways

- Spider-Man and Hulk both confuse Perry with Howard the Duck.

Phineas and Ferb Save Summer
- "Oh, great. They have a cave troll."
- When the characters are in the UK◊ in Summer all over the World, they not only manage to reference The Beatles' Rooftop Concert, but the gang are also wearing outfits inspired by Doctor Who characters. Concept art◊ shows that the reference was going to be even more explicit.
Phineas and Ferb Star Wars
Night of the Living Pharmacists
- Plays off the title of George A. Romero's famous 1968 zombie film Night of the Living Dead for laughs.
- Even better, Romero voices the reporter on the street, Don Adaded (which sounds like 1978's Dawn of the Dead).
- Simon Pegg and Nick Frost do their Shaun of the Dead characters Shaun and Ed in this episode.
- A callback to The Rocky Horror Picture Show in one scene where Phineas, Ferb, Candace, Isabella and Vanessa do the Janet-Dr. Scott-Janet-Brad-Rocky gag. Small wonder Richard O'Brien, who created the film (and stage show) is Lawrence's voice actor.
- A reference to Sir Francis Bacon when both Buford and Doof make comments to "shaking bacon". Bacon died studying how meat would be in a frozen state.
- Buford makes a couple to Aliens, doing his best Corporal Hudson impression, such as "Game over, man! Game over!" And later, ranting about "They're gonna come in here, they're gonna come in here!"

- Ferb quotes Egon Spengler when he says that he's "terrified beyond the capacity for rational thought."

- C'mon! Isn't anybody going to point out the truckload of World War Z shout-outs?!!
The End of Summer
- One of the sneak peeks released shows the gang and Candace in a washed-out and empty city with time-holes opening up. Dialogue indicates that they have to get back into the flow of time; this is reminiscent of the Stephen King novel The Langoliers.
- The effect of the Do-Over-Inator bears a striking resemblance to the 12th Doctor's new title sequence for Doctor Who.
- One of the things to be sucked through the holes in time during the "Groundhog Day" Loop are the groundhogs.
