|“|| Are we ever gonna see Phineas and Ferb as teenagers?|
Yes. Yes, we are.
— Jeff “Swampy” Marsh and Dan Povenmire
In this special episode set ten years in the future, a teenaged Phineas must decide between two colleges while grappling with the discovery that Isabella has had a crush on him since they were kids. Ferb and the gang try to bring the two together so they can admit their true feelings for each other before Isabella leaves for school. Meanwhile, Doof wants a midlife crisis and builds a Mid-Life Crisis-Inator.
In a live-action intro, Dan Povenmire and Jeff "Swampy" Marsh, the creators of the show, read some fan letters. One of the letters asks if they will see Phineas and Ferb as teenagers, and Dan replies they will and introduce the episode taking place ten years in the future.
As summer reaches its end, a teenaged Phineas is contemplating to Ferb which college or university he should go to, being the only one in their friend group who hasn't decided where he's going yet. Ferb suggests that Phineas get in the randomizer booth they'd installed in their room and let fate decide. Phineas gets into the booth, which is full of the many acceptance letters he had received from different schools around the world. However, he is not really sure about any of the choices he is given. Baljeet comes into the room and mentions that he had just been telling Buford about what life is like in college. He tells them that he has already graduated and is now a professor, and is hoping for Buford to attend his classes; though Buford is leaning towards attending film school instead. Buford suggests to Phineas that maybe he would be happy going to the same school as Ferb will be attending in Britain, while Baljeet suggests him to going to law school like Candace, but Phineas turns these suggestions down. He finally narrows down his choices between two colleges, Danville University and Tri-State State College.
At O.W.C.A., Irving, now working as an intern, notices Doofenshmirtz’s inator alert going off and informs his superior, Commander Carl. Carl is surprised by this, since Doofenshmirtz had given up evil years ago, ever since he started teaching high school science. Carl decides to tell Major Monogram about the alert. Monogram, who has since retired to Bora Bora, reminisces upon hearing that Doofenshmirtz may have returned to evil, and tells his former intern to say hi to Doofenshmirtz for him. Carl then calls Perry, who is also enjoying his own retirement. After hearing that Doofenshnirtz may be active again, Agent P gets back to work.
In the kitchen, Phineas, Ferb, Buford and Baljeet are all making snacks for themselves. Still on the topic of colleges and universities, Baljeet tells Phineas that Isabella will be attending Tri-State State, and Phineas mentions that he had not seen Isabella all that often over the past summer. Baljeet mentions that he had always believed Phineas and Isabella would have ended up as a couple by now, but Phineas says he feels as though he is stuck in the friend zone with her. Both Baljeet and Buford are amused by this thought, since they both knew about Isabella's crush and even Ferb, though Phineas himself had no idea. Surprised by the revelation that Isabella had always had a crush on him, Phineas decides to clear his head by going for a walk. Buford and Baljeet then decide to try to get Phineas and Isabella together before she leaves.
Meanwhile, at the building formerly known as Doofenshmirtz Evil Incorporated (the word "evil" has since been removed from the sign), Perry arrives to visit his old grey-haired nemesis. Doof is confused to see Perry today, since it is not bowling day, but then realizes that he must have set off the inator alert. Perry gestures toward a menacing-looking machine behind him, and Doofenshmirtz assures Perry his latest inator is not evil, and that the menacing-looking machine behind them isn't even the inator. The real inator is a gold chain he had been working on, which, when activated, will help him go through a Mid-Life Crisis so he can fit in with other people his age, which he explains through song. After the inator is charged up, Doofenshmirtz's mid-life crisis begins.
At the Nosh Olé Mexican-Jewish Café, the now teenage Fireside Girls discuss the art of manipulation when Ginger attempts to persuade Baljeet to go to the movie she wants to see, rather than the one he wants to see. Isabella, who is working as a waitress there for her mom, brings the girls their order. Gretchen asks where Baljeet is, and Ginger replies he is at Phineas' house. The girls also contemplate how Phineas and Isabella are not a couple. Deciding that they should take it upon themselves to set Phineas and Isabella up with each other before she leaves for college, Adyson instructs Ginger to text Baljeet about their plan. In the living room, Baljeet receives Ginger's text, but does some manipulation of his own to make it seem like it was Ginger's idea all along.
Doofenshmirtz, who has now dyed his grey hair black and is riding a jet-ski with Perry, crashes his jet-ski into a sailing yacht. Excited in the heat of the moment, he then suggests taking the yacht for a spin, but the yacht sinks and Doofenshmirtz's hair dye begins to wash off in the water, making it grey again. Doofenshmirtz then decides to get a sports-car and swims his way back to shore.
At the Danville Retirement Home, Phineas meets up with Nana Shapiro. Phineas tells Nana he is still indecisive about where to go to college. Nana then mentions that Isabella came over to say goodbye, which surprises Phineas since Isabella's college does not start for another two weeks. Nana tells him she is actually leaving today as soon as her waitress shift ends at the Café. Nana Shapiro suggests he go to the restaurant if he has anything to say to her.
In the backyard, the teen Fireside Girls, Baljeet, and Buford begin setting up a romantic dinner for Phineas and Isabella. Ferb suggests to leave well alone and not force them to get together, but Adyson suggests otherwise. Gretchen explains further the romantic dinner and Katie ask if it doesn't work that Buford brings the sign to show them "Think About Love".
At a car shop, Doofenshmirtz is looking at sports cars to try out. He tries a red one, but he crashes it. The salesman tells him they have the same model in yellow. This excites Doofenshmirtz.
In the kitchen, the girls are all cooking the dinner. Baljeet suggests to Buford that he wear the cupid costume, since it worked for him and Mishti, but Buford refuses. Upon hearing about Mishti, Ginger begins to get jealous, but Adyson tells her to let it go.
In downtown Danville, Doofenshmirtz is taking his new sports car and Perry for a wild ride. During this, they latch onto a dumpster. Doofenhsmirtz lets it go at the next turn and the dumpster speeds past the restaurant.
Isabella begins to say goodbye to her mother as she gets ready to go to college. Her mom gives Isabella her final paycheck and a hug. As Isabella walks away and begins to put her paycheck in her wallet, a photo of Phineas drops out. She picks up the photo then begins to reminisce about all the past summers she spent with Phineas and contemplates What Might Have Been.
Phineas reaches the restaurant, but Vivian tells him he just missed her. She then tells him she knew about Isabella's crush as well. Phineas leaves and does some contemplating of his own in the song about how oblivious he was to Isabella, even though, in hindsight, her attempts at romantic advances were really obvious.
Back in the backyard, Ferb puts a vase of flowers on the table and the girls believe the dinner to be perfect. They attempt to call Isabella on their cells, but various things hinder them from doing so. They are so distracted that they fail to notice the dumpster from earlier rolling into the backyard and taking the romantic dinner away.
By this point, Doofennshmirtz and Perry are in a plane about to skydive. Doofenshmirtz decides to hit on the cute jump instructor, but she pushes him out of the plane. Perry acknowledges her politely and quickly jumps out before she has the opportunity to push him too. As they fall, Perry opens both his and Doofenshmirtz's parachutes. Doofenshmirtz decides he has had enough of his mid-life crisis and takes the inator off and drops it. Below, the inator latches onto Lawrence, who, under the effects of the inator, rushes into the kitchen and tells Linda that he is impulsively going to switch his morning tea from Earl Grey to Darjeeling.
Phineas reaches Isabella's old house, but then notices her sitting on one of the steps of his house across the street. He walks over and sits next to her. Isabella tells him she came to say goodbye since she's heading to college early, because she has been accepted into various extracurricular activities at the school. Phineas then tells her what Baljeet said to him about her having a crush on him, which Isabella admits to. She then says she gave up on the idea of getting together with him around high school, and Phineas admits that was when he began to have feelings for her. The two sadly contemplate the bad timing of their respective crushes on each other. Isabella then mentions that she is going to Tri-State State, which makes Phineas' decision about which college to go to easier: he decides to attend her college so they can be together. The Fireside Girls and Baljeet, Buford and Ferb, who had come around the house from the backyard while Phineas and Isabella were talking, overhear their conversation and are happy to see that they are together now. Phineas and Isabella embrace, and Isabella gets back in her car, telling him that she'll see him in two weeks, and drives away. Ferb approaches Phineas and commends him for his choice. Vanessa then drives up in the yellow sports car and Ferb gets into the passenger's seat. They offer Phineas a ride, to which he accepts.
While driving, Isabella comes to a stoplight, and Vanessa's car pulls up next to hers. Phineas gets out of the backseat, and Isabella gets out of her car to ask Phineas what he is doing. Phineas replies, "This," and then kisses her. Off to the side, watching from their car, Vanessa jokingly tells Ferb that she never realized Isabella had a thing for Phineas, to which he replies, "Seriously?" She then tells him that she knew all along, and that everyone knows, before the light changes to green and they drive off. As Phineas and Isabella kiss, she tells him that it was worth the wait, to which he agrees.
Swampy begins to sob uncontrollably when seeing the gang all grown up and going to college. Dan tries to console him, but excuses himself and leaves the still weepy Swampy alone.

I know what we're gonna do today
The "Too Young" Line
Swampy: Are we ever gonna see Phineas and Ferb as teenagers?
Dan: Yes. Yes, we are.
Isabella: Well, I guess I'll see you in two weeks.
Phineas: Yes. Yes, you will.
Isabella: That was worth the wait.
Phineas: Yes. Yes it was.
Phineas: Ugh! I'm running out of time, Ferb. I gotta choose a school. Do I stay local or go abroad? Trade school? Art school? Come on, Ferb. Help me make a decision.
Ferb: Get in the booth.
Phineas: Okay, Kjobstaad Academy. Uh, which one was that again?
Ferb: Mmm...great physics department, Norway.
Phineas: Yeah. He's going to Camford on Oxbury. Heh heh! "Camford on Oxbury". It sounds like a wizard school.
Ferb: It's not a wizard school. Well, there is some wizarding.
Adyson: And when we get them to come back here and see it and each other, they're bound to fall madly in love like they were always meant to be!
Ferb: You know, you can't force these things.
Ferb: So Tri-State State, huh? Good choice.
Phineas: Hi, Nessa! Where're you guys goin'?
Vanessa: Oh, Ferb's takin' me out for Ukranian food.Ferb: Can we drop you anywhere?
Vanessa: I never knew she had a thing for him.
Phineas: So she's...leaving?
Baljeet: Yes. Huh. I always thought the two of you would end up together.
Phineas: Whatcha doin'? Heh heh.
(Isabella looks up and smiles.)
Isabella: Phineas, what are you doing?
Phineas: This. (Phineas kisses Isabella)
Hey, where's Perry?
Perry's entrance to his lair
Perry is sleeping and receives a call from Commander Carl
Oh, there you are, Perry
Doofenshmirtz hmm-hmm Incorporated!
Phineas: Yeah, things seemed a lot easier when we were young and waiting for our voices to drop.
Baljeet: [deep voice] Hey, guys. (coughs, normal voice) Oh! Something was caught in my throat.
Baljeet: I was just giving Buford some pointers on collegiate life. Since I've already graduated and have been accepted as a professor, I could pull some strings and get him into my school. Just think, Buford. You could be my student! I could be the boss of you!
Buford: Don't get too excited. I'm goin' to film school. I'm concentratin' on tragedies. The story of a struggling orphan's transcendental search for meaning in a post-apocalyptic society.
Candace: And that concludes my dissertation on modern investigative techniques for establishing proof of guilt with or without physical evidence.
(The judges all give her a standing ovation.)
Buford: Hey, the epic struggle of a triangle-headed boy: to choose between two schools.
Baljeet: Pretentious alert.
Irving: (on the phone) Sir, it's the old Evil Scientist Alert System! It's showing inator activity on a Doctor Dooferdsmits.
(Split screen to reveal Carl, now much older and wearing a uniform and mustache much like Major Monogram did.)
Buford: (looking in the fridge) Why do parents buy such weird food? Everything's lite, low, non, free, or diet.
Phineas: Well, why didn't you guys ever tell me?
Baljeet: We are guys. We do not talk about feelings.
Doofenshmirtz: I wanna do something fun and exciting and...also incredibly stupid.
Holly: Ginger, are you texting Baljeet again?
Ginger: Yeah, we're at odds deciding what movie to see later. He wants to go to the one about that planet and I want to see the one with that guy.
Isabella: Do we have chopped liver? What do you think this place is? Chopped li— Oh, that doesn't really work.
Buford: Ginger texting you again?
Baljeet: Yes. The girls want to get Phineas and Isabella together.
Doofenshmirtz: Hey, this is one of those fancy sailing yachts! We could sail around the world in this thing! We could, we could visit exotic ports, fight pirates! We'd like a couple of seafaring Huck Finns and the ocean would be our home! Or maybe we could wrestle some alligators! No, wait, even better, sports car!
Nana Shapiro: Phineas, look at me. If you have anything you need to say to her, you'd better go over to the restaurant and say it. Her summer's almost over.
Phineas: I—You're right. Thanks! (he runs off)
Gretchen: When they first walk in, we'll play the songs I put on this playlist. They're all about love, and it will trigger them to start thinking about love. Then we have these streamers and balloons in both of their favorite colors, which will stimulate the romantic centers of their brains making them think about love.
Katie: What if it doesn't?
Doofenshmirtz: Sure you don't have anything else that's more ridiculous or irresponsible?
Salesman: Nope. This is as dumb as they come.
Doofenshmirtz: So, what else ya got?
Salesman: We've got another one just like it, but in yellow.
Buford: Oh, yeah, it's the perfect romantic setting out there. It will be like love kicked them both in the face.
Baljeet: Buford, the table looks great, but there is one thing that will make it perfect.
Ms. Garcia-Shapiro: Phineas, honey, how are you?
Phineas: Hi Ms. Garcia-Shapiro. Uh, is Isabella here?
Adyson: Alright, let's get 'em over here now. (takes out her cell phone) Oh, wait, I don't have any charge.
Gretchen: Oh, this is her old number.
Doofenshmirtz: (to the jump instructor) Hi there. Y-Y'know, one of the best things about being a successful scientist is that I get to meet lots of attractive women, such as yourself.
Jump Instructor: You want to know the best part about being a jump instructor?
Lawrence: Linda! I don't know what's come over me, but I'm starting to get the most wild and uninhibited ideas! You know how every day for the last 20 years I've relaxed with a nice cup of Earl Grey? Well, not today, Linda! Today, I'm putting out all the stops! Darjeeling!
Linda: You...are a madman.
Phineas: You know, Baljeet said something funny. He said you had a crush on me back in grade school.
Isabella: Oh. Yeah. I had a big crush on you.
Jeff "Swampy" Marsh: (sobbing) I can't believe it! It seems like only yesterday we were drawing our first doodles of these kids on the place mats of that...
Dan Povenmire: (consoling Swampy) Yeah, I, I know, it's a... It's a sweet episode.
Dan Povenmire: (to Jeff "Swampy" Marsh) Oh, get a grip, Swampy.

- During the song, flashbacks are seen from the following episodes:
- Ferb's crush on Vanessa makes a reappearance with them going out on a date. ("I Scream, You Scream", "The Chronicles of Meap", "Vanessassary Roughness", "Summer Belongs to You!")
- In scene where Isabella asks Phineas what he is doing, he replies, "This" and proceeds to kiss her. Jeremy said the same thing to Candace right before they had their first kiss in "Phineas and Ferb Summer Belongs to You!".
- Family Guy - Dan and Swampy appear reading mail as Brian and Stewie do in "Viewer Mail".
- Harry Potter - Phineas mentions that the school Ferb will be attending in England, Camford on Oxbury, sounds like a wizard school. Ferb denies this, before admitting that there is some wizarding.
- The Crystal Maze - When Phineas is in the booth surrounded by flying paper it looks similar to the final round of the UK game show (originally presented by cast member Richard O'Brien)
- The Diamond Head Game and Beat The Clock - The booth that Phineas and Ferb use to decide what college to go to bears a resemblance to the volcano wind machine from the 1970's Hawaiian based The Diamond Head Game and the 'Swirling Whirlwind of Cash and Prizes' from the 2002-2003 version of the classic stunt show Beat the Clock.

- Third time Isabella and Phineas kiss (Phineas and Ferb The Movie: Across the 2nd Dimension, "Phineas and Ferb: Star Wars"), and the first time Phineas kisses Isabella. The previous two times, Isabella kissed him. Though, this is the first time the regular universe versions of Phineas and Isabella have ever kissed, to their knowledge (The real first time was erased from their memory in Phineas and Ferb The Movie: Across the 2nd Dimension, and the only other time it happened was to the alternate versions of them in the "Star Wars" universe).
- This is one of the many episodes in which Perry doesn't battle Doofenshmirtz, due to him giving up on evil.
- Perry doesn't interact with any of the kids in this episode, only with Doofenshmirtz and the OWCA members, and he is not shown in his "dumb animal" persona. None of the kids comment on his absence.
- If Perry was adopted five years before the series and this episode is placed ten years later, then he must be at least fifteen years old here, but he doesn't seem to be old in this episode. In Phineas and Ferb's Quantum Boogaloo, 20-years-later Perry does look old and wrinkled. Platypi in captivity have lived to age 17.
