Desmond: Art asked for a couple of slides.
Owen: What? I gave him a couple.
Desmond: "Couple" means "two".
Owen: No, it's like "few"; it indicates a range of values.
Desmond: Your parents are a couple. There are just two of them.
Owen: Not if you count Aunt Talia. Well, she's not really my aunt... She just sleeps over a lot.
