Shrek: Ogres are like onions.
Donkey: They stink?
Shrek: Yes. No.
Donkey: Oh, they make you cry.
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 onion.
