This is a parody of Aragorn's riddle. For all of you who haven't read the
book, that's the poem that Arwen's whispering (Arwen always whispers) when
Andùril (aka Aragorn's cool shiny sword) is being remade by elvish smiths
from the shards of Narsil (aka the broken piece of metal that Boromir cuts
his finger on)

All that is gold must glitter
And all those who wander are lost.
The dead that yet live always shiver
And hope has an over-high cost.
From the cinders a flame will be risen
Consuming all living things
Hobbits should all be death given.
I, undeserving, am king.

To continue my collection of songs parodied from the Lord of the Rings, I
shall now take my famous rendition of a song that Tom Bombadil (a guy who
wasn't mentioned at all in the movie and therefore isn't known to any who
haven't read it) should have been singing. Lot's of people loved him, but
I think 'thigh slapping winnie-the-pooh' was a good description of him
personally (from 'A Brief Guide to The Lord of The Rings)
Hey! Come derri-doll merry-doll,
I'm absolutely insane.
Tom Bombadil's a loony chap
With whom to spend a coupl'a days.
So let's all get drunk
And totally stoned at my house and sing-sing-sing.
I can't take anything seriously,
Not even Sauron's ring!
I'm a blithering idiot!
Come derri-doll, merry-doll
I'll waste up all your time
By sitting in my pretty house
Smoking and sculling wine.
Oh Frodo's having nightmares,
But who but Samwise cares?
I warned them when they came here
That they were in for some little scares.
With the night there comes a darkness
And all recoil in fright;
But stick with Bombadillo and
He'll make you feel all right.
Oh come merry-doll,derri-doll
The rest of the world can wait
Because we're having so much fun
And Gandalf's gonna be late
Anyway!
So come derri-doll merry-doll- HAH!
(this house is actually the loony bin)
And we're gonna have so much fun
With Pippin, Merry, Sam and Frodo
With his little ring!
