Anyone remember bugles? The cone-shaped fried thing that was obviously about as bad for you as any food possibly could be?

Can anyone explain to me why the serving size is done in cups? Has anyone ever tried measuring a cup of bugles? do you stack the bugles for optimum space usage? Is it just come as they are?

Not that I eat bugles anymore...but I find this fascinating. Is there any snack food that would be harder to measure by the cup?
