Thandie Newton: Libby
Dennis : I thought it would be a good chance for me to get to know Whit a little better, so...
Libby : Well, maybe we should all go out to dinner then?
Dennis : Really?
Libby : Yeah, and then we could go dancing...
Dennis : You're joking...?
Libby : No, not at all. And afterwards we could come back here and have a threesome.
Dennis : [thinks it over] You *are* joking.
Libby : Of course, I am!
