Shrek: So what day *would* I have to give up?
Rumpelstiltskin: [carving a rat] Oh, I don't know, any day. A day from your past. How about the day you had the flu? A day you lost a pet?
[resentfully and faster]
Rumpelstiltskin: A day some meddling oaf stuck his big nose where it didn't belong, destroying your business and ruining your life?
[the knife shatters the plate, calming down]
Rumpelstiltskin: Just for an example.
