NBC may be holding off on declaring this season the last for Frasier, but the show's producer, Paramount, sure isn't. Earlier this week, the studio mailed to members of the Television Critics Assoc. (like me!) invitations to a press conference in early January with show execs and cast members "on the occasion of their final season." The invite was accompanied by a sleeping mask adorned with the words "Goodnight, Seattle" — a riff on Frasier's signature radio sign-off. Paramount could not be reached for comment, but an NBC spokesperson maintains that — despite the mounting evidence — a decision about Frasier's future has not been made. In the meantime, I'm going to start the bidding for the sleep mask at $20. Do I hear $25?
