Princess Fiona: [as ogre] Donkey, shh, shh. It's me... in this body.
Donkey: [gasps] Oh, my God, you ate the princess!
Donkey: Wait a minute, I know what's going on. You're afraid of the dark.
Princess Fiona: Why... yes!
Donkey: Don't worry, princess. I used to be afraid of the dark until... No, wait. I'm still afraid of the dark.
Now really, it's rude enough being alive when no one wants you, but showing up uninvited to a wedding?Lord Farquaad
Princess Fiona: [turns into an ogre] I wanted to show you before.
Shrek: Well, er, that explains a lot.
Donkey: You love this woman, don't ya?
Donkey: Do you wanna hold her?
Donkey: Please her?
Donkey: Then ya gotta, gotta try a little tenderness! Chicks love that romantic crap.
The Donkey: So, uh, are there any donkeys up there?
Shrek: Well, there's, um, Gabby, the Small and Annoying.
The Donkey: Okay, okay, I see it now. The big shiny one, right there. That one there?
Shrek: That's the moon.
The Donkey: Oh, okay.
The Donkey: Shrek.
Shrek: What? It's a compliment. Better out than in, I always say.
The Donkey: But that's no way to behave in front of a princess.
[Fiona burps louder]
Princess Fiona: Thanks.
The Donkey: [to Shrek] She's as nasty as you are.
Princess Fiona: The battle is won. You may remove your helmet, good Sir Knight.
Shrek: Uh, no.
Princess Fiona: Why not?
Shrek: I have helmet hair.
Princess Fiona: Please. I would'st look upon the face of my rescuer.
Shrek: Oh, no, you wouldn't... tst.
Princess Fiona: But... how will you kiss me?
Shrek: What? That wasn't in the job description.
Donkey: Maybe it's a perk.
Donkey: Hi, princess.
Princess Fiona: It talks.
Shrek: Yeah, but it's getting him to shut up that's the trick.
Princess Fiona: What kind of a knight are you?
Shrek: One of a kind.
Princess Fiona: You didn't slay the dragon?
Shrek: It's on my "to do" list. Now come on.
Princess Fiona: But this isn't right. You're meant to charge in, sword drawn, banner flying-that's what all the other knights did.
Shrek: Yeah, right before they burst into flames.
Princess Fiona: What are you doing? You know, you should sweep me off my feet out yonder window and down a rope onto your valiant steed.
Shrek: You've had a lot of time to plan this, haven't you?
