When not at home, always only the twig, not the berries...over the waist band of the underwear and through the pants zipper since the front flap in most drawers are practically useless.
At home if I'm standing it's the same, though I sometimes in addition to the zipper will unbutton the first button on whatever pants I happened to be wearing. But half the time the berries are emancipated as well by virtue of the fact I pee sitting down quite a bit just because I'm both lazy and it avoids any chance of hitting outside the target area and thus keeps the marital peace.
