Sid: For a second there, I actually thought you were gonna eat me. Diego: I don't eat junk food.
Diego: [playing peek-a-boo] Where's the baby?... There he is! [the baby's only reaction is blinking; it is so startled it's quieted] Diego: Where's the baby?... there he is! Manny: [the baby begins crying again] Stop it, you're scaring him!
[passing a Stonehenge-like structure] Manfred: Modern architecture. It'll never last.
Manfred: Diego, spit that out. You don't know where it's been.
Dodo: This is our private stockpile for the Ice Age. Sub arctic temperatures will force us underground for a billion, billion years. Manfred: So you got three melons?
Diego: I've eaten things that didn't complain this much.
Sid: [about the baby] I bet he's hungry. Manny: How 'bout some milk? Sid: Ooh, I'd love some! Diego: Not you. The baby. Sid: Well, I ain't exactly lactating right now, pal. Diego: You're a little low on the food chain to be mouthing off, aren't you.....
Diego: "Us"? You two are a bit of an odd couple. Manfred: There is no "us"! Diego: I see. Couldn't have one of your own, so you decided to adopt.
[Sid's trying to use the baby to get attention from girls] Sid: I'm begging you. I need him. Manny: What, a good-looking guy like you? Sid: Aw, you say that, but you don't mean it. Manny: No, seriously, look at you. Aw, those ladies, they don't stand...
Sid: [after Diego snuffs out the fire on his tail] Thank you. From now on, I'm gonna call you "Diego..." Diego: Lord of Touch Me and You're Dead.
Manfred: [watching the dodos] Hey, look at that. Dinner and a show.
Diego: The baby? Please. I was just returning it to its herd. Sid: Oh, yeah. Nice try, Bucktooth. Diego: You calling me a liar? Sid: I didn't say that. Diego: You were thinking it. Sid: [whispering, to Manny] I don't like this cat. He reads minds.
Dodo: Prepare for the Ice Age. Sid: Ice Age? Diego: I've heard of these crackpots.
Glyptodont: So, where's Eddie? Glyptodont: Oh, he said something about being on the verge of an evolutionary breakthrough. Glyptodont: Really? [Eddie is seen running off a cliff in the background] Eddie: Look, I'm flying! [thud] Glyptodont: Some brea...
Carl: [to Sid] Look, we're gonna break your neck so you don't feel a thing. How's that? Manfred: Wait a minute. I thought rhinos were vegetarians. Sid: An excellent point! Manfred: Shut up. Carl: Who says we're gonna eat him after we kill them? Frank...
Diego: Whoo, yeah! Who's up for round two? [pause; embarrassed] Diego: Um, t-t-tell the kid to be more careful.
Diego: Is its nose dry? Sid: That means there's something wrong with it. Diego: Someone should lick it, just in case.
Manfred: If you find a mate in life, you should be loyal. In your case, grateful.
