"I've got a theory that it's the One Ring..."

Bwa-haha! Some folks have written “Once More with Hobbits”, rewriting the songs from the musical Buffy episode for an NYC Lord of the Rings line party (though I don’t know when or where). “Going Through the Motions”, “Walk Through the Fire”, and “I’ve Got a Theory” are the best pieces:

GOLLUM:
Our Precious thing, it calls to us
But we promised to obey
We hopes he fries, we're free if Master dies
We'll helps him on his way
