How did Bilbo answer when Smaug asked who he was in The Hobbit?

According to the book The Hobbit by J.R.R. Tolkien:

Smaug asks, "Who are you and where do you come from, may I ask?"

Bilbo answered, "You may indeed! I come from under the hill, and under the hills and over the hills my paths led. And through the air, I am he that walks unseen. I am the clue-finder, the web-cutter, the stinging fly. I was chosen for the lucky number. I am he that buries his friends alive and drowns them and draws them alive again from the water. I came from the end of a bag, but no bag went over me. I am the friend of bears and the guest of eagles. I am Ringwinner and Luckwearer; and I am Barrel-rider."
