Well, since I can't make this thread any worse (or is it, any better?) I will inject two literary not-metaphor-metaphors:
King Lear (Act 5, Scene 3): with Cordelia dead in his arms:
Never, never, never, never, never!
Pray you, undo this button: thank you, sir.
Do you see this? Look on her, look, her lips,
Look there, look there!
Moby Dick:
All that most maddens and torments; all that stirs up the lees of things; all truth with malice in it; all that cracks the sinews and cakes the brain; all the subtle demonisms of life and thought; all evil, to crazy Ahab, were visibly personified, and made practically assailable in Moby Dick. He piled upon the whale’s white hump the sum of all the general rage and hate felt by his whole race from Adam down; and then, as if his chest had been a mortar, he burst his hot heart’s shell upon it.
