If I were Eru, I would:
-Make a hailstorm in Mordor and have huge hailstones hit Sauron
-Make Denethor's clothes fireproof
-When Frodo puts on the Ring at Mount Doom, turn everyone's clothes hot pink
-When Shelob comes, have Tarentella start simutaniously
-When the Fellowship leaves Rivendell, have Frodo trip and have everyone trip over him (for lack of the devil smilie) >:}
-Have Aragorn trip up everytime he wants to say something
-Have Arwen have a heart attack when she chooses mortal life
-Have the ring turn into a fish and have Gollum eat it and become sick with a nameless desease
-FIND PJ AND HAVE HIM GET THE MOVIE RIGHT!!!!!!!!
Off topic: I'm still mad about Faramir being stripped of his glory that he had in the book!
