Martin: Oh, come on, Niles, why don't you tell me what's really on your mind?
Niles: All right, Dad, I was worried about you.
Martin: I knew it. Because I'm an old man and I can't take care of myself.
Niles: No. Age has nothing to do with it. I've always worried about you. That's what it's like when your father's a cop. I worried about you when I was five years old. And I didn't stop worrying until the day you retired. And today just brought it all back again.
Martin: Look, I'm sorry. For what it's worth, I know what you mean. My dad was a cop, too.
Niles: I know.
