Stranded on an island, a group of schoolboys degenerate into savagery.

Ralph: Whoever holds the conch gets to speak.
[all are marching and singing in cadence. One sings a sentence, the others repeat it]
Luke: Mama, mama can't you see? / What the Army's done to me? / They put me in a barber's chair. / Spun me 'round, I had no hair./ I used to drive a Cadillac. / Now I'm marching in a pack. / I used to drive a Chevrolet. / Now I'm marching for my pay. / They took away my T.V. / Got me doing I.T.
Piggy: We might have to live here for a long time! Maybe the rest of our lives! If we *are* stuck here until we get old, then we can't go on acting like kids! We've got to be sensible and make things work!
Ralph: [looking up] No!
[a rock is pushed off the cliff above, killing Piggy]
Ralph: You're not gonna get away with this.
Jack Merridew: Yeah? Well, what are you going to do, huh?
Piggy: What's your name?
Ralph: Ralph.
Piggy: I don't care what they call me, as long as they don't call me what they did in school.
Ralph: What's that?
Piggy: They used to call me Piggy.
Ralph: [laughs] Piggy!
Piggy: As long as you don't tell the others.
Ralph: [thinking about Simon's death] Piggy?
Piggy: Huh?
Ralph: Piggy, that was murder.
Piggy: You stop it! What good are you doing talking like that? It was dark. There was that bloody dance. There was thunder and lightning and rain. We were scared. It wasn't what you said.
Ralph: [sobs] Oh, Piggy!
Piggy: [comforts him] It was an accident. He was batty. He asked for it. It was an accident.
Ralph: Oh, God, I want to go home!
Jack Merridew: See you tonight, girls.
Ralph: Someone has to stay behind. Piggy...
Jack: [interrupts] Sure, protect Piggy like you always do.
Ralph: Don't be stupid. What can he do with just one eye?
Jack Merridew: Right on, Larry. When you other brats get older or get hungry enough, you can come join up, too.
Ralph: His name's not Fatty. It's Piggy.
Roger: LOOK! The beast!
Piggy: I've got the conch!
[the boys jeer and taunt him from above the cliff]
Piggy: [shouts] Which is it better to be, a pack of panting savages like you are, or sensible like Ralph is? Which is better, to have rules and degree, or to hunt and kill?
[Roger goes angry and pushes a huge boulder, which heads right to Piggy]
Piggy: AAH!
Ralph: Piggy!
[the boys go silently still as they see Piggy's body wash away in the sea]
Jack: We've got to have rules and obey them. After all, we're not savages. We're English! And the English are best at everything!
Ralph: You let the fire go out.
Jack: We needed meat.
Tony: What are we gonna do with thieves when we catch them?
Ralph: We can't have kids stealing and just running wild. We're going to have to have stricter rules and hand out demerits... I guess.
Piggy: We did everything just the way grownups would have. Why didn't it work? Things would be much better here if it wasn't for him. I wish he was dead.
Ralph: No, you don't.
Piggy: I do! We could just give up and join his tribe. Then we'd at least be with the others.
Ralph: No, Piggy.
Piggy: Ralph... I can't see.
Ralph: I know.
Jack Merridew: What won't matter?
Piggy: Whether we get rescued
Jack Merridew: You better start learning to live with yourself, because we ain't gonna get rescued
Piggy: What are you talking about?
Jack Merridew: Just being logical, a plane goes down in the middle of the ocean, theres no wreckage, who's gonna find us?
Piggy: Why don't you just shut up!
Jack Merridew: Are you telling me to shut up?
Piggy: What we need around here is positive people, not people trying to scare people!
Jack Merridew: What we don't need around here is you shitbrain!
Sam, Twin #1: His name's not shitbrain, It's Piggy!
Jack Merridew: Yeah Piggy!
Ralph: Shut up! Everybody just shut up!
[last lines]
[Ralph and the boys come out of the jungle where they encounter a Marine officer and several marine soldiers on the beach]
Marine Officer: What are you guys doing?
Jack Merridew: Whats the matter tits! Were you afraid to bring it with you? Anyway the conch doesn't count anymore, Miss Piggy-tits!
Ralph: Stop that!
Jack Merridew: Nobody's interested in you and your fucking conch! Why don't you just take your fat friend and shove off! you've had all the meat you can eat. Come on hunters! Rogers the pig!
Ralph: The reason I'm calling this assembly is, too much people are screwing around when they should be working. I mean theirs a bunch of things. Some people don't even know when to use the bathroom.
Tony: Yeah. Theres this one kid, the other day he took a shit in his pants and later sat on it, I'm not naming names because it's possible that Mikey couldn't help it.
Piggy: You and your blood, Jack Merridew! You and your hunting! We might've gone home!
Jack: We needed meat.
Piggy: You didn't not to have let the fire go out!
[Jack slaps Piggy across the face making Piggy's glasses fall off]
Piggy: My specs!
Simon: [picks them up] Here. Here they are.
[Piggy puts them on but realizes one of the lenses have cracked and missing pieces]
Piggy: [vengefully] JUST YOU WAIT!
Jack Merridew: Whats this dumbshit I hear about a monster? We're gonna have to send you back to kindergarten!
Larry: I'm serious.
Jack Merridew: Ok what kind of monster? Did it have fur and poison fangs, or long slimy tentacles?
Larry: It growled and it came out of me and it's mouth, it was wet.
Luke: Maybe it was a bear.
Roger: Sounds more like a reptile.
Jack Merridew: Sounds more like bullshit.
Larry: Sir, are you the leader?
Pablo: Jack's the oldest, but Ralph's the colonel.
[group voices votes for Ralph]
Jack Merridew: I guess you just won the election.
Ralph: It doesn't matter who's in charge. We've just got to work together. First, we build a camp.
Ralph: You're a beast, and a swine, and a bloody, bloody thief!
Piggy: [crying] Oh my God! They broke my Glasses!
Piggy: What good is that gonna do? They can't cook pigs without a fire. They'll get trichinosis.
Jack Merridew: Rodge, you okay, man? That was some jump.
Roger: I got him. Right up his ass.
Sam, Twin #1, Eric, Twin #2, Pablo, Andy: Up the ass!
Will: Come on, cut it out!
Ralph: Stop it!
Will: You dorks, it hurt!
Sam, Twin #1: I know it hurt.
Ralph: Face it Jack, you fucked up! We could've been rescued.
Jack Merridew: Back off man! I'm sick of your shit and so is my gang.
Ralph: Your gang. What's that supposed to mean?
Jack Merridew: What it means colonel, that no ones good for you and stop trying to run everything.
