Quote from Niles in Cranes Unplugged
Niles: Freddie, about what you just saw. I know you've always had special feelings for Daphne, and there's something I need to tell you. Frederick: I already know about you guys. Niles: Oh. Uh, and you're OK with that? Frederick: I liked her when I was a little kid. I'm over it now. I mean, she's like a hundred. Niles: She most certainly is not. It just burns you up that I got her- Frasier: Niles!
