Frasier: Look, Lilith, all my life, I've had a problem talking about death. I know it's irrational, but I can't help feeling that if you talk about it, it'll happen.
Lilith: Well, Frasier, it will happen.
Frasier: Stop it.
Lilith: What, do you think if I hadn't mentioned it, you'd live forever?
Frasier: Well, now we'll never know, will we?
