Ellie: We've been living above an entire world, and we didn't even know it!
Sid: [confronting a Tyrannosaurus who has come looking for her babies] Look, these are my kids! And you're gonna have to go through *me* to get them!
Manny: Sid, whatever you're doing, it's a bad idea.
Sid: Shh! My kids will hear you.
Manny: They're not your kids, Sid. Take them back. You're not meant to be a parent.
Sid: Why not?
Manny: First sign: stealing someone else's eggs. Second sign: one of them almost became an omelet.
Manny: [Buck looking very spaced out by Crash and Eddie's lack of understanding his eye prospect turns to Manny who said in a slight sarcastic voice] Welcome to my world!
Sid: [As, Sid fails to fight back against the boiling lava river and is doomed to certain death as he gets nearer to the lava falls, he stands up dignified on his floating rock, putting his hand to his chest] This... is the end of Sid the sloth...
[Falls over lava falls]
Sid: Aaggghhhhh!
Manny: Guys don't talk to guys about guy problems. They just... punch each other on the shoulder.
Ellie: That's stupid!
Manny: To a girl. To a guy that's like six months therapy! Fine.
[walks over to Diego, punches him in shoulder]
Diego: Ouch. What was that for?
Manny: [pause] I
don't know.
Ellie: [Grabs fern] Here, boy! Here! Come on! Good boy! Come on! Climb on.
Manny: Are you nuts? We're not getting on that thing!
Ellie: It's either this dinosaur or that one! Pregnant lady wants to live! Yabba-dabba-doo!
[Slides down dinosaur's back]
Ellie: That's right sweetheart, welcome to the Ice Age!
Buck: [Buck sees a large butterfly as it takes off] I knew that guy when he was a caterpillar, you know, before he came out.
