I’m listening to the season one soundtrack from Battlestar Galactica. Track 16, “Battlestar Operatica”, is a lovely, very operatic piece, complete with Italian lyrics. The liner notes helpfully provide those, in Italian and English:
Italian:
*Maledetto sia tuo cuore Cylone
C’è una tostapane nella tua testa
E porta tachi a spillo
Numero Sei ti chiama
Il rivelatore Cylone impone
La tua ragazza è un tostapane
Maledetto sia tuo cuore Cylone
Ahimè, disgrazia! Ahimè, tristezza e miseria!
Il tostapane ha un bel vestito
Rosso come la sua spina dorsale ardente
Sussura Numero Sei
Per tuo comando*
English:
*Woe upon your Cylon heart
There’s a toaster in your head
And it wears high heels
Number Six calls to you
The Cylon Detector beckons
Your girlfriend is a toaster
Woe upon your Cylon heart
Alas, disgrace! Alas, sadness and misery!
The toaster has a pretty dress
Red like its glowing spine
Number Six whispers
By your command*
:snerk!: 
“La tua ragazza è un tostapane” would definitely be a useful phrase to remember for your next trip to a science fiction convention, in case someone cuts in line in front of you or something.
Bravissimo, Bear McCreary!
