Four Legs good, Two Legs Bad

One. Two. One. Two. One. Two. One, two. He stumbles. Pausing to catch his breath, the Hobbit looks up at the sky and wonders.

Why do I only have two legs? Surely four would be better. Four, like a horse. No beast of burden has two legs, and this burden is so heavy...

Sighing, he looks down at the rocky ground on which he stands. Slowly, and with great effort, he begins to move forward once again. One. Two. One. Two. Always the same rhythm, eating into his head, even as the chain ate into his neck. Frodo trudged on.
