I couldn't help but notice that the producers of both Cheers and Frasier used an invisible wife character, Norm Peterson's wife Vera, and Niles Crane's first wife Maris, who were never actually seen or heard, but yet had some kind of presence on their respective shows.
Charlie's Angels had Charlie, who was never seen, but could be heard on the phone.
Deal or No Deal had "The Banker", who only made the phone buzz.
Are there others?
