But she's not their daughter, Dear Lady - not in the least... but... well... she could be... you never can tell... what with movie magic and poetic license and the will to dominate and all....
Eegad!
Excuse my language, Dear Lady, for 'eegad' is used in the place of another word which is surely not to be used in the presence of well-to-do hobbits lasses or lovely elvish maidens, one of which I assume you to be; and I beg your pardon, Dear Lady, if you happen to be neither.
Eegad!
You are not, pray tell, one of those body-doubles I've been hearing tell of...!?

Nay, Dear Lady! You are clearly far too innocent and fair for that!

I hope GB doesn't read this - for he seems quite fond of you, and I fear he will fill up with with umbrage and righteous discontent! Yes, I have shown myself for the vulgar Stoor from Rushock Bog below Needlehole that I truly am. Yea, I have shown my quality, and it is of the lowest sort. Clearly no gentle-hobbit!
