Don't known if there is a specific term for this, but I'm looking for further excamples like this:
"Role Players" that do not really appear (or not in full) in TV series (or Movies) but are somehow there
in most episodes.
Like:
Inspector Columbo's wife (or totally other aspect: his first name)
Howard Wolowitz's mum
"Mr. Masters" in Magnum
Tim's neighbor in "Home Improvement"
Charlie in Charlie's Angels
