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.
Mr. Fantastic: Galactus must have seen us. Why didn't he say anything?
Uatu: Do you greet the cockroaches on your kitchen floor?
Keesha Franklin: It must be cold down there because Saturn's pretty far away from the sun.
Tim: But Ms. Frizzle said "cold and dark."
Janet: It could be very, very dark on Saturn.
Carlos Ramon: Oh, no you don't! You just want to grab more stuff.
Janet: Hey, I'm just trying to help! If you want to play "Let's Find Ms. Frizzle Without A Map" for the rest of your life, that's fine with me.
