Sheila: I want you to know that I love Sam and I'm going to do everything I can to make this marriage work.
Frasier: Well, you certainly do seem sincere about this. I think, in all good conscience I can support this marriage, but I want you to know if you start to feel yourself slipping, here's my number. [he hands Sheila his card, she looks offended] No, no, no. So I can help you as a psychiatrist!

Frasier: You know, in a way we're both in the same boat.
Sam: Yeah? What do you mean?
Frasier: Well, you know, we've tried, we've failed. But we'll try again. Sam, we're looking for a meaningful relationship.
Sam: Yeah, that's it. That's the word right there, "meaningful."
Frasier: We're gonna find it though, buddy. I tell you.
Sam: You bet we will. You know, stewardesses usually hang out at that airport bar.
Frasier: That says meaningful to me.
