When Tom thrusts his final thrust and shoots a billion Bombadillos deep into Goldberry's loins, the impact would shatter Sauron's soul into a billion Saurodillos and he would be free. When this happens, not even the wisest can tell.

His spirit would be released to the boundless void that ripples and contorts with Tom's mighty thrusts and he would find no solace.

Wishing to die but unable to kill himself as he doesn't even have a fucking hand to pull the trigger, he would order his orc armies to piss on him, so that the flames of his eye can be extinguished and his mind can be set free of Tom's all encompassing girth.
