So after you beat the main game and the finale movie starts to run, Chell's upward elevator-ing is abruptly halted by a quartet of turrets. Rather than shoot at you, they start to… sing?
What are the turrets singing about? Is it Latin? (And even if it isn't, what are the translated lyrics?)

Maybe we will never know for sure what are the the correct, "official" lyrics, but we know they are Italian (or something that resembles Italian), and also that some unofficial translations got pretty close.
