One really funny intersection of all this is the origin of "it's not over till the fat lady sings". It comes from the woman who played Brünnhilde in one of the original productions of Wagner's ring cycle. And you see her.....she's obviously fat. But today she'd be considered smallfat, not even to the level of planet. And she was considered so grotesquely large that the spectacle of her size dominated people's perception.
