William Shakespeare's The Empire Striketh Back, by Ian Doescher

C-3PO:
My R2 small, pray be thou safe, good friend,
And take especial care of Master Luke.
Farewell, farewell! parting is such sweet sorrow
That I shall say farewell till thou hast left.

R2-D2:
[aside] "Till thou hast left"? No poet he, indeed.
Alas, it seems that romance is not one
of 3PO's six million forms of speech.
