Today: Bill the All-Powerful Pony

I read a fanfic a while ago...LOTR...and in it Bill the Pony took over the world. He stole the Ring of Power from Frodo and ...Okay, so it was a little weird. Anyway, I was wondering if any of you happen to know where I can find it. When my computer crashed I lost all of my favorites. I cannot even remember which fansite it was posted on. If you happen to know of this particular story, give a shout! (You don't need anymore details, trust me. If you read it you'll know...:).
