Mr. Krabs: No, SpongeBob, that doesn't cheer me up at all!!!
Girly Teen Girl: I'm here for the slumber party.
Pearl: Oh, really?
Girly Teen Girl: Yeah. My name is... Girly Teen Girl. I'm from... FarAwayVille.
SpongeBob: Oh, I do, Mr. Krabs. It must be horrible to invite people into your home and have them treat your property with so little respect!
Mr. Krabs: That's what teenagers do! Do you want this to happen to my house?
SpongeBob: Gosh, no, Mr. Krabs.
Girl: Boys are here!
Boy Fish: Hi, girls. I brought my destructive friends.
Mr. Krabs: And it's ice cold, too. You should've been back here in 30 minutes or less! (takes another slice)
SpongeBob: Piano repair man!
Pearl: Sure, SpongeBob. If you can prove you're the most fun person on the planet in the next ten seconds, you can stay.
SpongeBob: I only need eight!
SpongeBob: Give me one good reason why I can't stay!
Pearl: I can give you a hundred million billion reasons!
SpongeBob: Yeesh, I only asked for one.
Pearl: Reason number one: you're just like my dad!
Pearl: A no-good, dried-up, old fuddy-duddy!
SpongeBob: So if I prove I'm fun, can I stay?
SpongeBob: (gurgling) Who wants to dance?
Girl: No! I already have a zombie boyfriend!
SpongeBob: Mr. Krabs, I think I know what'll cheer you up.
Mr. Krabs: Right, boy! (drives off without SpongeBob)
SpongeBob: Um… uh… (moustache flutters away) Hey!
SpongeBob: They're on to us, Mr. Krabs! Drive!
SpongeBob: You're dad sent it. It's already paid for.
Pearl: I'd sooner believe space aliens sent me a free pizza before I'd believe my dad would! Now, who are you?
SpongeBob: (with pizza box) Pizza delivery.
Pearl: We didn't order any pizza!
SpongeBob: Y-You didn't?
Mr. Krabs: Don't say that. Here, would your friends want some pizza?
Pearl: Well, yeah, yeah we would.
Pearl: No dancing, no loud music after 7:30, no touching the root beer cellar?
Mr. Krabs: Look, I'll stay upstairs in me room and not interrupt.
Pearl: You promise?
Mr. Krabs: I promise.
Mr. Krabs: Oh, hi pumpkin. I was just setting out refreshments for your friends. (hands one to Pearl)
Pearl: Crackers and tap water? You are the cheapest crab alive.
Judge: No, the snail didn't win. Your other pet did. He's so adorable!
Patrick: (panting) Woof woof!
(Girly TeenGirl runs out crying)
Mr. Krabs: Who was that?
SpongeBob: I don't know, but she's uuuugly.
