Frodo: What news of the outside world? Tell me everything. Gandalf: Everything? You are far too eager and curious for a hobbit.

Frodo: Come on, Sam. Remember what Bilbo used to say: "It's a dangerous business, Frodo, going out your door. You step onto the road, and if you don't keep your feet, there's no knowing where you might be swept off to." 

Frodo: Mordor, Gandalf, is it left or right?

Frodo: Gandalf, I'm glad you're back. 
Gandalf: So am I, dear boy. So am I. 

Bilbo: You will keep an eye on Frodo, won't you? 
Gandalf: Two eyes, as often as I can spare them.

Frodo: Before you came along, we Bagginses were very well thought of. 
Gandalf: Indeed? 
Frodo: Never had any adventures or did anything unexpected. 

Gandalf: My dear Frodo. Hobbits really are amazing creatures. You can learn all there is to know about their ways in a month, and yet after a hundred years they can still surprise you. 

Smeagol: Come on, Hobbits. Long ways to go yet. Smeagol will show the way.
