Monica: What happened to your teeth?
Ross: I whitened them.
Ross: Yeah, what... What do you think?
Monica: Well, uh, I think I shouldn't look directly at them.
Ross: Come on, seriously.
Monica: Ross, they're really, really, really white!
Chandler: Yeah, what was wrong with your old... Human teeth?
Ross: Well, I did leave the gel on a little longer than it said to.
Monica: How much longer?
Ross: Uh, uh... A day.
Monica: Ross, you know that tonight is your date with Hillary?
Ross: I know! That's why I did it! Come on, are they really that bad?
Chandler: No. No, no, no, you'll be fine. Hilary's blind, right?
Monica: She will be after tonight.
Citizen G'Kar: I believe that when we leave a place a part of it goes with us and part of us remains. Go anywhere in these halls, when it is quiet and just listen. After a while you will hear the echoes of all of our conversations, every thought and word we've exchanged. Long after we are gone, our voices will linger in these walls for as long as this place remains. But I will admit that the part of me that going will very much miss the part of you that is staying.
Mr. Fantastic: Galactus must have seen us. Why didn't he say anything?
Uatu: Do you greet the cockroaches on your kitchen floor?
