It's the inscription on the Ring of Power, sought after by Bill Gates, to make his conquest of Middle Earth complete.
In the Orcish tongue of Microsoft it reads: "One OS to rull them all, one OS to find them, one OS to bring them all and in the darkness bind them. In the land of Microsoft where shadows lie."
Let us hope I never have to utter those words here again. This is supposed to be a holy place.
Ash OS durbatulk, ash OS gimbatul,
Ash OS thrakatulk, agh burzum-ishi krimpatul!
Uzg-Microsoft-ishi amal fauthut burguuli.
