Why Bilbo?

As I read the book The Hobbit, I keep asking myself why any group that has the motives that this particular group had would pick a "person" like Bilbo to basicly lead them. I think that I would have looked around the mountain a little more before I went and mocked on that hobbit hole. Bilbo is such a weird character in the beginnig of the book. He is somewhat of an annoying character in the ways that he is so particular about teh ways that things are arranged. Any man that woories about teh food situation and had such an abundant of clothes is definitly an odd character to me. As I keep reading teh book, however, I am starting to enjoy him more as he blossoms into the character that he ends up being.
