Niles: Well, Maris and I ran into each other on deck, and we had a long talk, and, well, she invited me back here for a glass of champagne.

Niles: Though it might mar the mood a bit if she finds you all spying on her! Did you use that mouthwash?
Frasier: No, Maris did.
Niles: My God, she's in the mood for more than champagne.
