Vitruvius: The Special has arisen.
Gandalf: Have the young man step forward.
Vitruvius: As you wish, Dubbledore.
Gandalf: I'm Gandalf!
Dumbledore: It's pronounced Dumbledore.
Vitruvius: Dubbledore?
Dumbledore: No, Dumbledore.
Vitruvius: I thought you said Dubbledore.
Gandalf: Vetruvius!
Vitruvius: Ah, we gotta write all that down 'cause I'm not gonna remember any of it, but here we go. The Special will now give an eloquent speech.
Emmet: I think I got it... But just in case... Tell me the whole thing over again, I wasn't listening.
Lucy: Come with me if you want to not die.
Batman: If this relationship is going to work out between us I need to feel free to party with a bunch of strangers whenever I feel like it. I will text you.
Emmet: Everything is awesome!
Abraham Lincoln: A house divided against itself... Would be better than this!
Emmet: Uh, guys? We're about to crash into the sun.
Batman: Yeah, but it's gonna look really cool.
Lord Business: Whoo! Nothing's gonna stop me now.
Vitruvius: Wait. There was a prophecy.
Lord Business: Oh, now there's a prophecy.
Vitruvius: About the Piece of Resistance.
Lord Business: Oh, yes! The supposed Piece of Resistance that can somehow magically disarm the Kragle. Give me a break!
Vitruvius: One day, a talented lass or fellow A Special One with face of yellow, will make the Piece of Resistance found from its hiding refuge underground and with a noble army at the helm, this MasterBuilder will thwart the Kragle and save the realm and be the greatest, most interesting most important person of all times. All of this is true, because it rhymes.
Lord Business: Oh, wow. That was a great inspiring legend... That you made up. A prophecy? What a bunch of hippy...dippy...baloney.
Benny: Spaceship!
Emmet: You don't have to be the bad guy. You are the most talented, most interesting, and most extraordinary person in the universe. And you are capable of amazing things. Because you are the Special. And so am I. And so is everyone. The prophecy is made up, but it's also true. It's about all of us. Right now, it's about you. And you still can change everything.
Duplo: We are from the planet Duplo, and we're here to destroy you.
Emmet: Oh, man.
Emmett: Isn't there also supposed to be a good cop?
Bad Cop: Oh yes but we're not done yet. [Changes to good cop.] Hi buddy! I'm your friendly neighborhood police officer! Would you like a glass of water?
Emmett: Yeah, actually. Thanks.
Bad Cop: [Changes back to bad cop and knocks the water away.] Too bad!
Emmett: That's the signal, but the shield is still up.
Batman: We'll wing it. [Smiles, looks at Emmett, and then frowns] That's a bat pun.
Vitruvius: Emmet, you didn't let me finish. Because I died.
President Business: All I'm asking for is total perfection.
Answer: The "it was cool" part means how Emmett saved the day and how his sacrifice made a good final battle. He's basically saying, even before Emmett made himself a hero, he still liked him anyway.
