Frasier: Now, now, Niles. It's only natural for you to feel a little bit shaky, but believe me, you made the right decision.
Niles: How do I know that?
Frasier: [picking up the journal] Let's just check what prompted us to it. Here: "Niles is incapable of asserting himself, especially in front of females."
Niles: Keep going. This is helping.
Frasier: "As I write this he lies, staring out the window, licking himself."
Niles: What?
Frasier: "He's become so subservient lately that when he's finished grooming himself he often begins licking Frasier."
Niles: I have no memory of that.
Frasier: "April 14th. The day I've dreaded for weeks: Frasier died this morning. I never would have guessed that my heart could ache so over the death of my beloved lab rat. My only consolation is the knowledge that I will soon give birth to my first child."
Niles: Frasier... do you know what this means?
Frasier: Our mother named us after rodents.
Niles: No. It means I have ended my marriage to the woman I love based on the case history of a spineless rat. Oh, my God!
