Ice Age: Dawn of the Dinosaurs

Buck: "There's only one thing to do. Possums, come with me. Manny, you stay and take care of her."
Manny: "You can't leave now! She's off the trail! What about rule number two?"
Buck: "Rule number 5 says you can ignore rule number 2 if there's a female involved, or possibly a cute dog. You know, I just make up these rules as I go along."

Buck: "Now then, eyes forward, back straight... oh... and breathe in the toxic fumes and you'll probably die."
Ellie: "Toxic fumes?"
Buck: "Just another day in paradise!"

"Bad egg! Rotten egg! A heart attack you almost gave me!"

Ellie: "This isn't your fault. It's bigger than both of us. We have to get Sid."
Manny: "Yeah. But if I have been a better friend to him... we wouldn't be here."
Buck: "Better friend, are you pluckin' my whiskers? You risked your life, your mate and your baby to save your buddy! Not the best husband or father... but a darn good friend!"

"Rule no. 1: Always listen to Buck! Rule no. 2: stay in the middle of the trail... and rule no. 3... [Long pause] he who has gas travels at the back of the pack."

"For the record, I blame you for this!"
[to Manny]

Buck: "It smells like a buzzard's butt fell off and was sprayed on by skunks."
Diego: "That's Sid."

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."
