Frasier: I'm just trying to do the right thing here. I'm trying to be the good son.
Martin: Oh, don't worry, son. After I'm gone, you can live guilt-free knowing you've done right by your Pop.
Frasier: You think that's what this is all about? Guilt?
Martin: Isn't it?
Frasier: Of course it is! But the point is I did it. I took you in. And I got news for you, I wanted to do it because you're my father! And how do you repay me? Ever since you moved in here, it's been a snide comment about this or a smart little put-down about that. Well, I've done my best to make a home here for you. And once. Just once, would it have killed you to say "thank you"? One lousy "thank you"?
Martin: Come on, Eddie, it's past your dinner time.
Frasier: I'm going out.
