I love it when Thorin kicks the other dwarves to shut them up when he realizes what Bilbo is doing.Kili when he says that he has the biggest parasites. "I've got parasites as big as me arm." Haha love this scene.
I actually would throw The Hobbit book at them and tell them they better read this. THEN, I would throw all THREE LotR books at them, make them read those, and OBVIOUSLY they will love it by then and we can watch the movies together.
