The Hobbit, or, There and Back Again
"I beg of you," said Bilbo stammering and standing on one foot, "to accept this gift!" and he brought out a necklace of silver and pearls that Dain had given him at their parting.
"In what way have I earned such a gift, O hobbit?" said the king.
"Well, er, I thought, don't you know," said Bilbo rather confused, "that, er, some little return should be made for your, er, hospitality. I mean even a burglar has his feelings. I have drunk much of your wine and eaten much of your bread."
"I will take your gift, O Bilbo the Magnificent," said the king gravely. (18.46-9)
