Samantha: I never leave underwear at a guy's place because I never see it again.
Charlotte: What happens to it?
Samantha: Nothing. I just never go back.
Carrie: Doesn't that get a little expensive, disposing of lingerie every time you sleep with a guy?
Samantha: That's why I stopped wearing underwear on dates.
Miranda: And that's why I'm never borrowing a dress from you again.
