To gild refined gold, to paint the lily.Plain as water.She's the apple of my eye. Sour as a green apple. Stand your ground.Season of mists and mellow fruitfulness.When the cows come home. To live from hand to mouth.Too little too late. Schools out for summer. Stir up an ant's nest. Walking on water.Sour as a green apple. Too little too late. Season of mists and mellow fruitfulness.A stick in the mud. Up one side and down the other. Useless as tits on bull.
