Quotes of O Mighty Shrek
"Shrek: Ogres are like onions.
Donkey: They stink?
Shrek: Yes. No.
Donkey: Oh, they make you cry.
Shrek: No.
Donkey: Oh, you leave em out in the sun, they get all brown, start sproutin' little white hairs.
Shrek: NO. Layers. Onions have layers. Ogres have layers. Onions have layers. You get it? We both have layers.
Donkey: Oh, you both have layers. Oh. You know, not everybody like onions."

Donkey: Hey, what's your problem, Shrek, what you got against the whole world anyway, huh?
Shrek: Look, I'm not the one with the problem, okay? It's the world that seems to have a problem with ME! People take one look at me and go "Aargh! Help! Run! A big stupid ugly ogre!" They judge me before they even know me - that's why I'm better off alone...
Donkey: You know, Shrek... when we first met, I didn't think you were a big, stupid, ugly ogre.
Shrek: Yeah, I know.
