Niles: Speaking of Daphne, I was hoping you could spare her this Friday. I'm planning on taking her for a weekend getaway, where I think we may be taking our relationship to the next level.
Frasier: Oh, my God, Niles. You're going to propose?
Niles: No, not that level, the level before that.
Frasier: You're going to ask her to move in with you?
Niles: One more level before that.
Frasier: Well, you're already dating...
Niles: No, that's two levels.
[Niles makes a hand gesture to indicate one level below]
Frasier: Oh, for heaven's sake, just tell me!
