Quote from Martin in Everyone's a Critic
Martin: So, are you sure you're okay with Niles getting this critic job? Frasier: Why wouldn't I be, Dad? Martin: Oh, come on, I know what it's like with you two when one of you gets something the other one doesn't have. It's just like when you were kids. Niles had a telescope, you had to have a telescope. You got that funny looking guitar, Niles... Frasier: Dad, it was called a lute. Martin: Yeah. Oh, yeah. Okay.
