Quote from Niles in Our Parents, Ourselves
Martin: Wow, you got a nickname down there already. That's great. The Coyote? Niles: Yes. Frasier: And how did you earn that honorific? Niles: Oh, it was quite the merry road. Yes. It evolved from Niles to Nilesy to Niley to Nile E. Coyote and now simply "The Coyote." [the group of men from the Shangri-La howl] Niles: Oh, well, just when I thought it couldn't be refined any further.
