【选段台词】

Griffin: I lost my planet. I don't want you to lose yours. It'll take a miracle, but if you pull this off, you'll be my new favorite moment in human history. Oh, dear. I forgot to see this one coming.

J: Damn it!

K: Have these in the future?

J: No.

K: Get on. Keep gyro settings at zero gain. Balance pitch and yaw with bursts on the center stalk between 80 and 100 psi.

J: I didn't understand any of that!

K: Gyro at zero gain.

J: It is.

K: Pitch and yaw with short bursts on the center stalk. Between 80 and 100 psi!

J: Got it.

Boris(young): The Arc Net! Give it to me!

Griffin: This isn't the one where you get it!

K: All right there, chief?

J: Hell, yeah. It'd be better with four wheels! Two is, like, my minimum.

K: What happens if Boris gets the Arc Net?

J: Boglodite invasion, total destruction of Earth!

Boris(young): The box! Good boy.

J: We gotta stop this guy!

K: I've been trying!

J: You haven't been trying?

K: Hey, slick.

J: Yes, sir!

K: Did you get him?

J: Give me a sec.

K: Is he dead?

J: Negative. He got away.

K: I got Griffin. Let's get out of here.

Boris(old): I feel younger already. You pathetic waste of Boglodite flesh. I'd kill you right now, if I didn't value my own life.

Boris(young): Who are you? 

Boris(old): Look at you. Every mistake I've ever made, just waiting to happen.

Boris(young): What happened to my arm?

Boris(old): You lose it, shot off by a human.

Boris(young): No human could defeat me.

Boris(old): You spend the next 40 years in prison, chained up like an animal.

Boris(young): No prison can hold me!

Boris(old): They built one especially for us, on the moon.

Boris(young): No human has been to the moon so they cannot have bulit it there already.

Boris(old): So stop arguing! You can avoid all of that if you just listen to me!

Boris(young): You were defeated! You let it get shot off! That wasn't me, that was you!

Boris(old): What's your plan?

Boris(young): Prevent the Arc Net from being deployed. Kill anyone who tries.

Boris(old): Good plan. Didn't work. With my help we'll get the Arc Net, kill Agent K the invasion will be successful and we'll get to keep both of our arm! Stop stare at it! Listen!

K: You all right?

Griffin: Yeah. Thank you for saving my life.

K: It's what we do.

J: You still have the Arc Net?

Griffin: When you're being hunted by Boris the Animal you get good at hiding things. This will save your world. Once it's outside the atmosphere, it gets a whole lot bigger. All you have to do is deploy it.

K: You mean in space? Well, how do you suppose we do that?

Griffin: It's just one small step.
