Tom Bambadil

Ok so all you lord of the rings geeks know who Tom Bombadil is for those of you who dont he is an utterly usless character. I dont know how J.R.R Tolkein came up with him. Who imagines hobos who sing there heads off and live in the middle of the forest, Not that J.R.R is a wacked character(He is still awsome) but I do not think he needed to write 2 chapters on him.
