I've always wondered about her, partly for other reasons.
She seems to be a sort of "go-to" actress when it comes to that. For one thing, you see her as an extra in a BOB NEWHART SHOW episode from the same year, when he has a larger group than usual (I should've been reminded of that when someone mentioned that "BOB NEWHART SHOW / COLUMBO" connection a while back). And I think several other things.
