Niles: You know what, I think I'm putting you on the spot here. Let's just leave it at congratulations on your new "relationship".
Frasier: What are you implying?
Niles: Oh, I think we both know what kind of "relationship" we're talking about.
Frasier: Would you stop saying the word "relationship" that way? "Relationship".
Niles: I'm not condemning you for your little "fling".
Frasier: Oh, for God's sake.
Niles: Just don't try to pass it off as something deeper than it is. The only thing you two have in common is the faint impression of the word "Sealy" on your backsides.
