Quote from Niles in Breaking the Ice
Frasier: Want to know the reason I came up here? Niles: Hmm. Frasier: It was just to hear him say the words "I love you." Niles: What? Frasier: Yeah, well, you know, he said it to Duke, he said it to Eddie. He's never said it to me. Niles: Surely you don't put yourself up there with Eddie? [they both laugh] Oh, Frasier, you know he loves you! Frasier: Oh, yeah, of course I do. I'm being ridiculous, I know that. I mean, look at the guy. He's content just to sit here freezing his buns off because we're sitting here with him. I guess I just got a little obsessed about, you know, hearing it. Well, I mean, you know that Maris loves you, right? But it's still nice to hear it. Niles: I imagine it would be, but let's stick to attainable goals.
