I think of hobbits as pandas. They must be coaxed into procreation. Too busy smoking pipe-weed and growing things and generally having hairy feet.
Also, I really cannot recommend this series highly enough. This is one of those transcendent forms of art to me. Like Cowboy Bebop and Calvin and Hobbes, this is a product I have no reservations about recommending to people. Unless you really hate anything sexual in books (and I know some people do).
