[Phineas and Ferb arrive at Mos Eisley spaceport to find R2-D2 and return the Death Star Plans data disc]
BBlatto
Phineas and Ferb! My best customers!
Hey, Blatto. We're trying to find an R2 unit and give him back this data disc. Hey!
BBlatto
[takes the disc out of his hand] Let's take a look at it. [puts it into an R2 unit's head and it shows a hologram of the Death Star]
Wow! It's an Imperial battle station the size of a moon! And according to these schematics, it seems to be designed specifically to destroy entire planets! Whoa, I never imagined the Empire would go that far! [Ferb points to an exhaust port] Huh, you're right, Ferb. One proton torpedo in that small exhaust port and the whole thing goes blammo!
BBlatto
Uh, it's like it's got a self-destruct button. What kind of idiot would design that?
[Cut to Darthenshmirtz having trouble getting a drink from the water fountain]
DDarthenshmirtz
Oh, why can't I master this?
[Back to Mos Eisley]
Wait, if the Rebels have this information, they might stand a chance against this thing. A small one-man fighter could penetrate the outer defense, fly along that trench, and get to the exhaust port.
That droid must be part of the Rebel Alliance! We've gotta get this disc back to him!
Isabella, did you know have T-27 thermal couplings up here?
Ferb and I can reroute their current to double up your power supply.
Just keep your paws off my ship. [writes down her notes] "Reroute thermal couplings."
I wonder what our friends and family are doing back on Tatooine. It feels a little strange to be so far from them. But at least we're making new friends. Like you, Isabella.
This is not a "friend" ship, it's a spaceship. So don't invade mine. We're coming out of hyperspace. Buckle up, ladies!
What do you think, Ferb? A girl like her and a guy like me?
As promised, the Millennium Falcon. I should be able to catch him before he gets to that small moon.
That's no moon. It's the Death Star!
[Aboard the bus pod…]
Can you believe this? Making us ride the bus pod? They better give us a real Rebel-fighting job this time and not just running some more errands.
[Buford is about to eat his hoagie, but as he looks in the bag, he's shocked to see that there's something different in there]
[looks in the bag; worried] Uh-oh.
I mean, how hard is it to deliver socks?
I believe Buford acquires your attention.
Oh. What is it, Buford? [Buford pulls out what is revealed to be Darth Vader's black socks] Huh. Uh, Buford, I'm going to ask you a question and I want you to think very hard before you answer.
I know. Here's the thing. If we have Darth Vader's socks, what exactly did we give the commander?
[Cut to the Death Star; Buford's hoagie falls on the ground and Darth Vader chokes the commander to death, using the Force]
DVDarth Vader
I find your lack of socks disturbing.
[notices Ferb holding his hand up while sensing something] What's wrong, Ferb? You got your hand up again.
Oh, no! We must go help him!
No. You must go get that disc to the Rebels. We cannot risk our mission.
Just do what you need to do fast and meet us at the Falcon!
May the Force be with you and all that stuff.
What happened, Solo, garbage scow tip over and dump you here?
HHan
What are you doing here, Isabella? Did someone run out of cupcakes?
Very funny. So where are you heading?
HHan
As far away from here as possible.
Yeah, I don't have any reason to stay here either.
Katie, bar the door. Is she back yet?
HHolly
No sign of her. We searched everywhere.
MMilly
Where could she be?
She’s probably still with Phineas and Ferb. She’ll make it.
[bells go off]
Perimeter alert! We have incoming!
Stations everyone. Put out that light. Katie?
KKatie
Yep. Friend or Pharmacist?
[Irving works as a new intern at the OWCA headquarters, taking over from now Commander Carl, heard a beeping sound and wipes the dust covering Dr. Doofenshmirtz's picture in the Evil Scientist Alert System.]:
Sir, it's the old Evil Scientist Alert System! It's showing "-inator" activity on a Doctor... Dooferd...
Doofenshmirtz? Great googly moogly! I thought he'd given up his evil ways when we placed him as a high school science teacher. It's too bad Monogram isn't around to see this.
Well, sir, he's gone to a better place.
Yeah. [self-reflecting as the music starts to fade] Oh what the heck, I'm calling him!
[Carl dials the telephone, and calls a now retired Major Monogram who is on vacation]
[responds to the telephone call while relaxing] Monogram...
Carl! I'm great. Bora Bora really is a better place. How have you been, man?
I've been well. Guess who's just set off the "-inator" alert?
[chuckles on the news] Just like old times. Well, tell him "Hi" from me.
[referring to his and Isabella's childhood and their wasted chances, in song] And now our endless summer is finally coming to an end;
I tried to make the most of every day, but now the years just seem mis-spent…
What might have been?
[Phineas arrives at Isabella's house. As the delivery truck moves away, Isabella is seen sitting down at the steps at Phineas' house. The two eventually looked at each other for a moment.]:
[walks towards Isabella] Watcha doin'? Hehe... [Isabella then smiles at him] Is this step taken? [referring to the steps at Phineas' house where Isabella is sitting]
[allows Phineas to sit beside her] I actually came by to say goodbye to you.
Yeah, I'm going two weeks early because I'm an RA, and in soccer, debate camp, student government.
Yeah. I haven't seen you all summer.
I've been busy. [Isabella pauses]
You know, Baljeet said something funny. He said you had a crush on me back in grade school.
Oh! Yeah, I had a big crush on you.
Really? I thought I was being so obvious.
Absolutely clueless. Sorry. [Phineas pauses]
I sort of gave up when we got to high school.
Yeah. I think that's when I started having a thing for you.
[The two then briefly pause as they both look at each other when Isabella realizes something]
Well, that's unfortunate timing.
Yep. You're off to college.
Tri-State State. Have you decided where you're going yet?
[Phineas brought out two acceptance letters he saved] You know what, I just did.
[Isabella glances at an acceptance letter from Danville U] Oh, huh.
Hey, what's wro-? [retrieves Danville U's acceptance letter from Isabella] Oh shoot! I'm sorry, heh, wrong letter. [passes Tri-State State's acceptance letter to Isabella]
Well, I guess I'll be seeing you in two weeks.
[Candace's alarm goes off saying "I know where we're gonna do today"]
I know what we're gonna do today.
And I know what I'm gonna do today! Bust you guys once and for all! Do your worst or your best. Just make it big and bustable, so I can show Mom!
Wow! That was awfully supportive. And you said Candace wasn't a morning person.
This is it, Candace: the last day of summer vacation! Your last chance to bust the- [Candace slips on a rollerskate and skateboard and falls down the stairwell onto a wagon] Why do we have this many... wheeled objects lying around the house?
[Last lines of the series]
[The entire cast enters the house as Candace and her brothers point and smile at each other. Before entering the house, Phineas waves goodbye to the viewers]
