Derek: Dr. Crane. We figured out what you were doing today, and thanks.
Frasier: I beg your pardon?
Derek: Well, you were letting us do all that stuff to you just so we could feel better about ourselves.
Syd: What a guy. You know, you've really got to care to go that far.
Frasier: How about that. They have figured it out.
Derek: This is the best group we ever had.
Frasier: [laughs] Yeah, well...
Lester: [mumbling] ...genius.
Frasier: Oh, well, I wouldn't really say "genius," Lester. That is what you said, isn't it? [Lester nods] Gentlemen, good night. Good night.
Derek: Thank you, Dr. Crane.
Frasier: You've all made wonderful progress today.
Syd: Thank you, Dr. Crane. Thank you very much. [group exits]
Frasier: You know, maybe in a hundred years, they'll be able to walk through a mall.
