Crackers

"Crackers" (named "Phineas and Ferb's 2nd Hawaiian Vacation" on Disney XD) is a fan fiction of Phineas and Ferb and Lilo and Stitch: The Series.

Story
The Flynn-Fletcher family, this time with Isabella, Buford, Baljeet, Stacy, and Irving, take a trip back to Hawaii. Phineas and Ferb and they're friends meet a young local girl named Lilo and her "dog", Stitch. Candace accidently activates Experiment 630, an experiment that can create cracks in the ground or in walls, so Phineas, Ferb, Lilo, Stitch, and the others must retrieve him before Gantu does. Meanwhile, Doofenshmirtz plans to use his latest device to steal all the fruit on Hawaii so he can power up his generator for his Rotten-Odor-Inator.

The "Too Young" Line
Jumba: Aren't you little too young to be playing with highly radioactive evil genious chemichals?

Phineas: Yes. Yes we are.

Jumba: Well, I am proud! You could grow up to be just like Jumba someday, small triangular-headed boy.

Phineas: Um... no thanks.

Pleakley: So, nobody's gotten hurt doing this before?

Ferb: No. No they haven't.

Pleakley: Oh, good.

Ferb: Nobody's ever tried this before. You're a first-timer.

Pleakley: Wait, WHAT?

The "Where's Perry?" Line/Perry's entrance to his lair
Phineas: Because you're pet is so neat, maybe you'd like our pet platypus, Perry.

Lilo: Well, where is he?

Perry tiptoes by with his fedora on. He comes up to Stitch. They both look at each other, then quickly react by both getting on all fours.

Stitch: Bark. Bark.

Perry: (Chatters)

Stitch walks off. Perry just continues moving with a creped out look on hisface.
