Dibs: If there's one thing that I've learned from you, it's "always kick 'em when they're down". And baby, you're six feet under. Oh, what a shame.
Kat: In two years I have been to nine different schools, eaten in nine cafeterias. I can't even remember anyone's name.
Dr. Harvey: Honey, I think it's time that we sat down and had a little talk.
Kat: It's a little late for that, Dad.
Dr. Harvey: How late?
Kat: Oh, don't worry, not that late.
Casper: God, I'd kill for a pinky.
Three ghosts: It's my party and I'll die if I want do, die if I want to. You will die too, when it happens to you.
Casper: I told you I was a good dancer. Can I keep you?
Kat: Casper?
Dr. Raymond Stantz: Who you gonna call?... Someone else.
Kat: Drop dead.
Stretch: Too Late.
[Casper sitting on his old sled, takes his baseball cap off]
Casper: I begged and begged my dad to give me this sled, but, be acted like I couldn't even have it, because I didn't know how to ride. But then one morning, I came down for breakfast and there it was! Just for me, for no reason at all. I took it out... went sledding all day... my dad said "That's enough" but I couldn't stop I was having so much fun... it got late... got dark... got cold... and I got sick... my dad got sad...
Kat: What's it like to die?
Casper: Like... being born, only backwards... I remember, I didn't go where I was supposed to go... I just stayed behind, so my dad wouldn't be lonely
Kat: Sometimes I worry that I'm starting to forget.
Casper: Forget what?
Kat: My mom. Just certain things. The sound of her making breakfast downstairs. The way she'd put on her lipstick, so carefully. I do remember... she always used Ivory soap, and when she'd hug me, I'd breathe her in, so deep. And I remember before I'd go to sleep she'd whisper in my ear, "Stars in the eyes, rosy cheeks, and a happy girl in the morning."... Casper?
Casper: Hmm?
Kat: If my mom's a ghost, did she forget about me?
Casper: No. She'd never forget you.
Amelia: For what you've done, I'm giving you your dream in return. But it's only for tonight. Sort of a Cinderella deal.
Casper: So I have until midnight?
Amelia: Ten.
Casper: Hey, Cinderella had until midnight.
Amelia: Cinderella wasn't twelve years old.
Casper: All I want's a friend.
Kat: You guys are disgusting, obnoxious creeps.
Stretch, Fatso, Stinkie: Thank you.
[After seeing a ghost]
Kat: Dad, I'm sorry.
Dr. Harvey: For what?
Kat: For not believing you, for thinking you were a total loser.
Dr. Harvey: Aww honey... apologize later!
Amelia: James, I know you have been searching for me, but there's something you must understand. You and Kat loved me so well when I was alive that I have no unfinished business, please don't let me be yours.
[Dr Harvey has died and come back as a ghost]
Dr. Harvey: Look at me! I've never felt so great in my life, I can fly!
[He crashes into the floor]
Fatso: Rookie!
Kat: I can see right through you.
Casper: Yeah, kind of happens when you haven't got any skin.
Three Ghosts: [brandishing swords] All for one and one for all!
Stretch: Catch your pants before they fall!
Casper: Kat? if I were alive, would you go to the Halloween dance with me?
