Niles: Well, we're all adults, I suppose we could just ask them what they have in mind.
Frasier: That's the worst thing we could do. What if they're not interested? They'll be embarrassed and it'll ruin the entire weekend.
Niles: I know. Their luggage will tell us. We'll put my bag in with your date's, and your bag in with my date's. They'll see the mistake.
Frasier: Right.
Niles: The way they correct it will tell us with whom they're planning to spend the night, each other or us. And either way, it'll all look like a simple misunderstanding.
Frasier: You've done this before.
Niles: Only on my honeymoon. Now, hurry.
Frasier: Niles, this is idiotic. We're both trained psychiatrists.
Niles: Yes, and finally it's paying off.
