For six years of The Big Bang Theory, we have listened to this very large woman continue to smother Howard, obviously never truly accepting that her little boy has grown up. It's her (incredibly loud) banter with Howard that makes her so special. Because she is never seen, they are always shouting at each other from different rooms. We never see her face though. Always heard, never seen, she none the less is a huge presence on the show.
Like Gunther or Janice, Ugly Naked Guy was one of those brilliant peripheral characters in Friends that fleshed out the world of this sitcom. Ugly Naked Guy was a man who made his presence known by not being on screen.
Yes, we know that with the closing moments of season eight and the entirety of the final series, the mother of Ted Mosby's children is going to finally make her presence known, but we have had eight years to learn little tidbits about a major character that we haven't actually seen.
After all the woman Ted has dated it is this woman that he chooses, a woman so special he gives up smoking two weeks into dating her, stays in New York (we assume), giving up a great opportunity in Chicago, finally gets married and has two children with her. Now we're finally getting to see her on screen!
The writers of Frasier once insisted that no actress could ever be cast as Maris Crane because frankly no-one could live up to the viewers (probably wildly differing) expectations. Niles Crane's wife (and later ex-wife) Maris went from being pencil thin to excessively obese.
As the series progressed we came close to seeing the elusive Maris on several occasions but each time the writers pulled back and merely added more weird and wonderful character traits for the viewer to ponder. Hats off to people behind Frasier for creating the ultimate unseen TV character.
Stan Walker was a character we got to know a lot during the first five seasons of Will & Grace but was never seen. His wife Karen, of course, was the highlight of the whole thing. All this drama for a central sitcom character, whose husband never had an onscreen appearance. Like many great unseen characters it was left up to the imagination. Why would Karen love an obese, balding man? Was it just his money or was it something more? Was he as charismatic as his wife? I guess we'll never know...
