I was amused listening to Cara mia Addio, Portal 2’s last track, sung by the turrets as a Farewell song.
Cara bel, cara mia bella!Mia bambina, oh ciel!Che ella stima!
Che ella stima!O cara mia, addio!
La mia bambina cara…perché non passi lontana?Sì, lontana da Scienza!Cara, cara mia bambina…Ah, mia ben!Ah, mia cara!Ah, mia cara!Ah, mia bambina!Oh cara, cara a mi…
Now, being Italian I could perfectly understand the lyrics, which basically sum up in, "Farewell my dear child, why don’t you stay away from Science?"
This song gives a whole new meaning to the theory
***SPOILER*** in which Glados, who has Caroline’s core and essence, is supposed to be Chell’s mother.
