Brick, Brick, Brick, Brick, Brick, Brick, Brick...It's Fun. (honk)
Brick Jokes in Phineas and Ferb.
- At the end of "Toy to the World", the creatively bankrupt toy executives are frantically trying to think of an idea for a new toy to follow up Phineas and Ferb's "Perry the Platypus Inaction Figure". They settle on marketing a brick to children. In another episode, Doofenshmirtz wants to destroy the billboard that blocks his view of the city skyline. The billboard advertises the Brick. With the same theme music in the background no less.
- In the first episode "Rollercoaster", Linda remarks that Candace is in charge in case of a satellite crashing through the roof of the house. Later, when the rollercoaster train is flung into space, Phineas spots a satellite going by and says "You know, if that thing crashes through the roof, Candace is in charge."
- This brick joke gets a brick joke seasons later, in "Rollercoaster: The Musical", although "a satellite crashing through the roof" is replaced with "a herd of moose charging through the living room".
- Comes back yet again in Milo Murphy's Law when it's revealed that Melissa has a fear of rollercoasters because the same rollercoaster that was built in the very first episode of Phineas and Ferb fell out of the sky and landed in her back yard nearly crushing her.
- In "Sci-Fi Pie Fly", Doofenshmirtz complains that one of his attempts at getting even with a pizza guy backfired when he turned his "exploding pizza dough" into a promotional gimmick. Near the end of the episode, Candace orders a pizza that turns out to be the exploding kind.
- In "Phineas and Ferb Get Busted", the hovercar's platform falls over and destroys a chunk of the house, which gets the boys sent to military school. Later, Jeremy walks in and says he came in through the big hole in the door, to which Candace says that the boys would have fixed it by then.
- In "Greece Lightning," the boys create chariots so that they can race like the ancient Greeks, but dress as gladiators. The next episode begins with Ferb casually mentioning that gladiators were actually Roman.
- In "Swiss Family Phineas", Candace suggests Phineas and Ferb build a giant slingshot to get off an island. Phineas likes the idea and asks if he can use it another time.
- This winds up being the solution to the Summer Belongs to You episode.
- In one episode Monogram informs Perry that he's getting a vase for Christmas. An entire season later, Doof gives him the aforementioned vase at the end of the Christmas Episode.
- In "The Lake Nose Monster", Doof writes "Big Laundry" on a chalkboard in his zinc-collecting vehicle and forgets what it means. He remembers what it meant in "Swiss Family Phineas".
- "Day of the Living Gelatin" introduced Pinky as a secret agent in O.W.C.A. (of a different division than Perry, who accidentally entered one of Pinky's transports trying to enter one of his own). He finally gets an episode to shine in "Isabella and the Temple of Sap".
- In "Canderemy", a beam from Doofenshmirtz's Combine-inator is split into two when reflected through a glass pane; while one half of the beam hits Candace and Jeremy, the other hits a satellite up in space, which absorbs its effects. The results of the beam hitting the satellite come back near the end when Phineas is about to go to a movie with Isabella, and the satellite releases the remaining effects of the Combine-inator which hits Phineas and Ferb, merging them together into a Phineas-Ferb hybrid.
- "Ask a Foolish Question" lampshades this when Baljeet remembers events on a monitor and acts the same as Isabella. A brick is the next thing that Baljeet thinks of.
- Marty the Rabbit Boy and his musical blender (from "Flop Starz") reappears in "Oh There You Are, Perry", with Candace (again) mistaking his silhouette for Phineas and Ferb.
- In the "Hawaiian Vacation" episode, when Doof mentions that he's going to leave using his "Bo-At, or 'boat' as he is now told it's pronounced," this is a callback to "Interview With A Platypus."
- The episode "Moon Farm" includes a catchy musical number that at one point has the singer say that they can't make rocky road ice cream because they left the marshmallows at home, and that he blames Baljeet. This results in...Baljeet: Hey, what do you mean you blame Baljeet?!
Disembodied Reggae Space Voice: Well, it was clearly your responsibility.
Baljeet: Where are you getting your information from, Disembodied Reggae Space Voice?!
Disembodied Reggae Space Voice: Hey, I have a NAME, you know!
Baljeet: Oh, yeah? What is it?
Disembodied Reggae Space Voice: Well... it's Disembodied Reggae Space Voice, but that's just a coincidence, you didn't know that!
Baljeet: Oh, look who is sensitive! Besides, Buford could have brought the marshmallows!
Buford: Hey, leave me out of this!
Phineas: Guys, guys, we have a limited time here! Baljeet, could you please stop arguing with the soundtrack?
Baljeet: He started it!- Then, when the song is repeated during the credits...Disembodied Reggae Space Voice: (singing) We left the marshmallows at home. I blame Baljeet.
Baljeet: Hey, I thought we discussed this earlier!
Disembodied Reggae Space Voice: It's in the lyrics, mon!
- Then, when the song is repeated during the credits...
- Peter the Panda from mid-season one's "It's About Time!" makes an awesome return in "Meapless in Seattle". Good to know they haven't forgotten where they mentioned their characters live. The two times they did. In passing.
- In "Tri-Stone-Area", when Phinabunk(?) and Gerb(?) are riding their newly-invented car, a caveman (named Conk) recognises them and says something like "Ahwah! Phinabunk an Gerb!" It might translate to "Oh heeeey! Phineas and Ferb!". Conk is the very same caveman from "Boyfriend From 27,000 B.C.". He even ends the scene with his foot encased in the glacier that will eventually cryogenically freeze him.
- When Candace sings “Come Home Perry” She says that she’ll change her name to Larry, (she ran out of rhymes). When Perry does come home, Buford addresses her as Larry when everyone leaves to celebrate.
- Candace had said a few times before that when she and Jeremy get married, she's going to have a boy and a girl and name them Xavier and Amanda. Come "Phineas And Ferb's Quantum Boogaloo", guess what two of her kids are named (there's another boy named Fred, as well).
- Both Candace and Doofenshmirtz have had moments where they are unable to think up a retort on the spot, only to come up with one later in the episode.
- In "That's the Spirit", after the kids' adventure of a "Scooby-Doo" nature, Phineas leans on the fourth wall and expects someone from the haunted house to turn into a ghost for real. They don't, but something similar happens next episode, in "The Curse of Candace", in which Candace has convinced herself she's a vampire, and when the boys prove otherwise and she takes off her sunglasses, she turns into dust and gets blown away by the wind.
- In "Meapless in Seattle", Candace is asked by Linda to take out the garbage only to drop it at the backyard door when she sees the big idea. The garbage ends up being forgotten and left at the door for the entire episode, and once Meap leaves in the end, Linda comes out and sees Candace forgot the garbage.Linda: Candace, I thought I told you to take that garbage out. You are so busted, young lady.
Candace: Of... course I am... - In "Act Your Age", Doofenshmirtz's sports car becomes attached to a dumpster, which Doofenshmirtz shakes loose at an intersection. Later in the episode, the dumpster careens through the Flynn-Fletcher backyard and destroys the kids' invention.
