- Dr. Heinz Doofenshmirtz: Wow, if I had a nickel for every time I was doomed by a puppet, I'd have two nickels - which isn't a lot, but it's weird that it happened twice.
- Phineas Flynn: [to Perry] You're a secret agent? And you've been living with us this whole time? Was that evil guy right? Were we just a cover story to you? I mean, were you ever really our pet or part of our family? Well, apparently not, 'cause you didn't trust us enough to tell us! Anyone else around here leading a bizarre double life?
- [Ferb raises his hand up behind Phineas's back]
- Phineas Flynn: [without looking at him] Put your hand down, Ferb.
- Isabella Garcia-Shapiro: It's weird that Perry's a secret agent, huh?
- Buford Van Stomm: Yeah, but it was obvious in retrospect.
- [2nd Dimension Isabella and her squad of Resistance have just captured the two sets of Phineas and Ferbs, and 2nd Dimension Buford in an elegant way]
- Isabella-2: [in a hipster voice] Whatcha doin'?
- Phineas Flynn: Well, I guess if you guys can't help us fix the remote, we could check with Isabella.
- Phineas-2: Who is Isabella?
- Phineas Flynn: The girl who lives across the street.
- Phineas-2: Mom says that talking to neighbours can be dangerous.
- Linda-2: [off screen] It's true!
- Phineas Flynn: Well, it's time you met her. Come on, you'll like her.
- Phineas-2: What about the Normbots?
- Phineas Flynn: Relax! We've been avoiding them all day. If you're really careful, you can...
- [a Normbot comes flying above their heads after they take three steps outside]
- Phineas Flynn: Okay, we've got to be more careful than that.
- Phineas Flynn: You know, I used to think you couldn't spell "platypus" without "us."
- Ferb Fletcher: Well, you can, but it would just be "platyp."
- Phineas Flynn: You know, if we had two Perrys, we could put a net between them and play platy-polt badminton
- Buford Van Stomm: Who's Annette?
- Phineas Flynn: Ferb, that's it! I know what we're gonna do today.
- Buford Van Stomm: No, seriously, who's Annette?
- Phineas Flynn: Okay, everyone, I think the tail is all set. I'll just go check with the foreman.
- Isabella Garcia-Shapiro: He's gone!
- Phineas Flynn: Hey, where's Perry? Did he really slip away? On his anniversary? Sometimes it seems like Perry's missed every single cool thing we've done all summer long. I guess he can do whatever he wants. After all, it's his day, right?
- [Perry stands behind the tree and throws a stone, which clatters to something]
- Baljeet Rai: Hey, what was that small noise?
- Phineas Flynn: Let's all go walk over to it!
- [Phineas, Ferb, Isabella, Buford and Baljeet all go over towards the noise while Perry goes into one of his secret entrances]
- Buford-2: [after destroying a Normbot] I can't stand these things!
- Phineas Flynn: Hey, it's Buford.
- Buford-2: Who are you guys?
- Phineas Flynn: We're Candace's brothers. We're going to Isabella's.
- Phineas-2: Are you part of the Resistance?
- Buford-2: I used to be in the Resistance, but I got so good at it that I started resisting them.
- [last lines]
- Isabella Garcia-Shapiro: Um, Major Monogram?
- Major Francis Monogram: Uhh, yes?
- Isabella Garcia-Shapiro: So none of us will remember ANY of today?
- Major Francis Monogram: That's right.
- Isabella Garcia-Shapiro: Good.
- [Isabella kisses Phineas]
- Phineas Flynn: [pleasantly surprised] Isabella!
- Isabella Garcia-Shapiro: Hit it, Carl!
- Phineas Flynn: Wait, wait, wait!
- [Carl hits the button of the Amnesianator]
- [Dr. Doofenshmirtz, Candice, Phineas, Ferb and Perry are linked together by a chain hovering over a lava pit. Candace catches a key]
- Dr. Heinz Doofenshmirtz: Oh, great, you caught it! Unlock me.
- Candace Flynn: Are you even paying attention?
- Dr. Heinz Doofenshmirtz: [realizing he would fall into the lava pit if he was unlocked] Uh, that's right, i... it can wait. Later.
- [Perry, shackled by chains to Phineas, Ferb, Candace and Dr. Doofenshmirtz, is holding onto the side of a cage above a lava pit]
- Phineas Flynn: Perry, let go!
- Candace Flynn: What? No! No! DON'T let go!
- Phineas Flynn: Perry, trust me!
- Candace Flynn: Two words, la-va!
- Phineas Flynn: So not only have you been leading a double life this whole time, but you sat there and let us help an evil scientist open an evil portal into an evil dimension - and you did nothing to stop us?
- Ferb Fletcher: Well, he did pee on the couch.
- Dr. Heinz Doofenshmirtz: Wait a second! I just realized. That was a conscious choice. You peed on my couch!
- Dr. Heinz Doofenshmirtz: I never built an Amnesianator! I think I'd remember building something like THAT.
- Phineas Flynn: [to Perry] Imagine how much fun we can have together now that we know you're a secret agent.
- Major Francis Monogram: Yes, yes, the, uh... next fifteen minutes should be a real hoot.
- Candace Flynn: [finds her parents in the cinema] Mom!
- Linda Flynn-Fletcher: Candace, what are you doing here?
- Candace Flynn: You gotta come outside and bust the boys!
- Linda Flynn-Fletcher: I'm not leaving now. The girl is about to forgive the guy for the cliché misunderstanding.
- [a Normbot comes through the screen]
- Linda Flynn-Fletcher: Well, after she battles these robots.
- Lawrence Fletcher: Whoa, this 3D is amazing!
- Phineas Flynn: One minute we were innocently launching ourselves across the city in a badminton platypult; the next thing we know, we're bouncing on up to the east side to your deluxe apartment in the sky.
- Doofenshmirtz-2: I spy with my one little eye a new tri-state area that's one dictator short of a dictatorship.
- Dr. Heinz Doofenshmirtz: You know, I can't help but notice that your scar goes over your eye patch.
- Doofenshmirtz-2: Yeah...?
- Dr. Heinz Doofenshmirtz: Nothing...
- Candace-2: You two, I've been spending all these years trying to keep my brothers safe, and suddenly their faces are all over the doofen-channel.
- Phineas Flynn: We're just trying to go home.
- Candace-2: Well, what's stopping you?
- Phineas Flynn: Right now? Quantam physics.
- [first lines]
- Phineas Flynn: [shackled along with his friends while being led to a large, caged, ferocious beast] I'll be honest, Ferb, I'm having a hard time putting a positive spin on this, but I guess that's life, huh? One minute you're having the best day ever, and the next you're being fed to a monster the size of a two-car garage.
- Doofenshmirtz-2: Anyway, I don't know why you're being so uncooperative. All I'm asking you to do is make my machine work so I can invade and conquer your world and enslave your loved ones.
- Isabella Garcia-Shapiro: Hi, Phineas. Whatcha doin'?
- Phineas Flynn: Turning Perry's involuntary reflex into a sporting event.
- Candace Flynn: Good-bye childhood folly, hello carefree, undemanding adult life!
- Linda Flynn-Fletcher: Yeah. Good luck with that.
- Phineas Flynn: [having learned that Perry is a secret agent] I'm... I'm sorry. I'm just having trouble processing this right now.
- [Perry whips out a pamphlet]
- Phineas Flynn: [reading] "So you've discovered your pet is a secret agent..." I don't want your pamphlet!
- Dr. Heinz Doofenshmirtz: Behold! The Other-Dimensionator! Actually, this is the OTHER Other-Dimensionator. The other Other-Dimensionator's back in the other dimension.
- Candace-2: I spent every day of my life trying to protect MY little brothers. I had to grow up pretty quick around here to make sure THEY didn't have to.
- Candace Flynn: Gee, you make growing up sound like it's a BAD thing.
- Dr. Heinz Doofenshmirtz: Okay, step one is - push this button. Step two, stand back in awe!
- [pushes button, machine producers one spark then quits]
- Dr. Heinz Doofenshmirtz: Awww...
- Stacy Hirano: Look, mysterious force? I feel a little awkward talking to you since y'know I didn't believe in you at first cause y'know it's crazy. But then I saw you... eat my friend.
- Doofenshmirtz-2: Y'know we're totally cool now, I'm just gonna go home and live out the rest of my days with my choo-choo. Ciao!
- [Doofenshmirtz steps through the portal to the other dimension]
- Doofenshmirtz-2: Ah home, it's good to be...
- [the members of the resistance show up in front of him]
- Doofenshmirtz-2: Uh-oh.
- Monogram-2: Book him, ladies.
- Doofenshmirtz-2: Y'know my crimes against humanity had just completely slipped my mind.
- Major Francis Monogram: Good job, Carl! If you keep up the great work, you'll make Unpaid Intern in no time.
- Dr. Heinz Doofenshmirtz: Holy boy! Even the great Francis Monogram's my slave in this dimension!
- Monogram-2: I prefer the term Indentured Executive Assistant.
- Doofenshmirtz-2: Oh, no, you don't! Ha-haa! Now the baseball is on the other foot! - or... however that saying goes.
- Jeremy-2: [breaks into Candace's cell] I'm Jeremy Johnson, I'm here to rescue you.
- Candace-2: Johnson, Jermey?
- Jeremy-2: [salutes] Yes sir, and I also picked up a couple new recruits.
- [Phineas-2 and Ferb-2 burst into the cell]
- Phineas-2: We found out a way to bypass the entire security grid, it was cool!
- Candace-2: What? You brought my little brothers? Are you out of your mind, solider?
- Jeremy-2: I didn't know they were your brothers, but I should've known. They're smart and courageous, just like you.
- Candace Flynn: So if there's another me, and another them, then there must be a Jeremy Johnson here too?
- Candace-2: Huh? Oh yeah. Johnson, Jeremy. Leads a three man strike team on the north side, good soldier.
- Candace Flynn: Good soldier? Is that all you think of him? I mean don't you think he's dreamy or cool or even cute? Tell me you at least think he's cute!
- Candace-2: Cute doesn't win the war kid.
