Bilbo: Oh, up to but not exceeding one fourteenth total profit if any. Seems fair. Present company shall not be liable for injuries including but not limited to laceration, evisceration... Incineration?
Bofur: Oh, aye. He'll melt the flesh off your bones in the blink of an eye.
Balin: You all right, laddie?
Bilbo: Yeah, I'll be. Feel a bit faint.
Bofur: Think furnace, with wings.
Bilbo: Yeah, I-I-I need air.
Bofur: Flash of light, searing pain, then poof, you're nothing more than a pile of ash.
Bilbo: [Long pause.] No. [Bilbo faints.].
Thorin Oakenshield: I would take each and every one of these dwarves over the mightiest army!
Gandalf: Home is now behind you. The world is ahead.
Thorin Oakenshield: I cannot guarantee his safety.
Gandalf: Understood.
Thorin Oakenshield: Nor will I be responsible for his fate.
Bilbo Baggins: I can't just go running off into the blue! I am a Baggins, of Bag End!
Old Bilbo: My dear Frodo, you asked me once if I had told you everything there was to know about my adventures. While I can honestly say I've told you the truth, I may not have told you all of it.
Gandalf: You'll have a tale or two to tell when you come back.
Bilbo Baggins: Can you promise that I will come back?
Gandalf: No. And if you do, you'll not be the same.
Answer: Hobbiton is the village where Bilbo was born. Overhill is on the northern edge of Hobbiton and Underhill is at the bottom of said hill. Built into the hill itself is Bag End, the Baggins estate. The Shire is the name of the Hobbit lands overall. So, he's from the village of Hobbiton in The Shire, and his home is Bag End, which is in the midst of the hill that forms both Overhill and Underhill.
