Gandalf: The world is not in your books and maps. It’s out there.
Bilbo: I can’t just go running off into the blue. I am a Baggins of Baggend.
Gandalf: You are also a Took. Did you know that your great great great uncle Bandobras Took was so large he could ride a real horse?
Gandalf: Well he could! In the battle of Green Fields he charged the goblin ranks, he swung his club so hard it knocked the Goblin Kings head clean off and it sailed a hundred yards through the air and went down a rabbit hole. And thus the battle was won and the game of golf invented at the same time.
Bilbo: I do believe you made that up.
Gandalf: Well all good stories deserve embellishment. You’ll have a tale or two to tell of your own when you come back.
Bilbo: Can you promise that I will come back?
Gandalf: No, and if you do, you will not be the same.
