- Dr. Heinz Doofenshmirtz: [just noticing Perry] Ah, Perry the Platypus! What an unexpected surprise. And by unexpected, I mean completely expected!
- Dr. Heinz Doofenshmirtz: [after the tin foil has come off of the buildings and flying towards his lair] Well, that didn't work. And now we have a two-ton ball of tin foil traveling 200 miles an hour directly at us!
- Dr. Heinz Doofenshmirtz: You did it! You saved us, Perry the...
- [tinfoil ball crashes into Dr. Doofenshmirtz's building]
- Dr. Heinz Doofenshmirtz: Curse you, Perry the Platypus!
- Phineas: It's Candace's birthday. We gotta do something better than last year.
- [cuts to gorilla jumping out of the cake as Candace runs away screaming]
- Dr. Heinz Doofenshmirtz: [with Perry in the hub trying to get to the surface] I hate to a stickler but the lava is coming again! Faster!
- Hub Computer Voice: Hub is overheating... Hub is overheating.
- Dr. Heinz Doofenshmirtz: [seeing the magma, beat] The molten lava at the Earth's core completely slipped my mind.
- Candace: [while Phineas and Ferb are buidling the rollercoaster] Will you hold it down! I am trying to use the phone!
- Phineas: [in space seeing a satellite] You know, if that thing crashes to Earth, Candace is in charge.
- Candace: You got to see what Phineas and Ferb are doing!
- Mom: Seems like we've had this conversation before.
- Candace: What do you mean?
- Mom: I seem to recall you telling me that the boys were training monkeys to juggle bicycles, and when I got home, there was a stunning lack of monkeys.
- Candace: I don't know how they cleaned that up so fast.
- Isabella: [after the roller coaster ride] That was great, Phineas. What are you going to do tomorrow?
- Phineas: Don't know yet.
- Isabella: Maybe you can teach Perry some tricks.
- Phineas: Well, he is a platypus; they don't do much.
- Ferb: They're the only mammals to lay eggs.
- Phineas: Maybe he'll lay an egg.
