Question Mark!
 

Unfortunately, the ring had not landed in the lava and was actually resting on the body of Gollum who had fallen and landed on a stalagmite.

Fortunately, a large rock fell and knocked it into the lava.

Unfortunately . . .
 

. . . the lava solidified before the Ring could melt.

Fortunately, the Orcs had given up on the idea of a motorised Orodruin and decided to pour the lava they had been using as fuel back into the magma chamber... where the ring was.

unfortunately the orcs cleaned out the chamber first, and they found the ring

Fortunately a big fight erupted over it and all the Orcs in the area killed each other off.

Unfortunately, the Nazgul flew in to break up the fighting, and in so doing found the Ring.

Fortunately, the Nazgul began fighting.

Unfortunately after the Barrow-wight threatened to kick them off the forum he took the Ring to Sauron.

Fortunately, Sauron was so occupied playing Werewolf, he didn't even notice the Ring, and so it just sat there beside him. :D

Unfortunately it was night, so Sauron got up to take a break and saw the ring there

Fortunately . . .
 

. . . Eru decided to change the fashions of the world again. So the Ring was suddenly transported to . . . Erebor?

Unfortunately it was picked up by a psychopathic Troll.

Fortunately a bunch of phsychiatrists(sp?) came and locked him in a padded room.

Unfortunately, the troll turned out to be a Balrog and burned the cell with his fiery sword!

Fortunately an ice-spear maker killed the Balrog with his ice spears.

Unfortunately, the ice spears all melted due to the Balrog's fiery heat before they could even touch him.

Fortunately, in the confusion, the Balrog dropped the ring and it rolled towards Frodo who happened to be there.

Unfortunately . . .
 

. . . it was not really Frodo, but a disguised Gollum. He takes the Ring and puts it on.

Fourtunately the place caugt fire cause of the balrog and the ring rolled to frodo.

Unfortunately, because of the smoke from the fire, Frodo was not able to see the ring as it rolled towards him, so it went right past his left hand and stopped in a pile of dirt in the corner.

Fortunately, the dirt was put in a bin, which was then carried away towards Mount Doom where they were now depositing the rubbish.

Unfortuantely the went to Mt.Zoom by accident

Fortunately, Mt. Zoom was what the Orcs had renamed Mount Doom to after they attached wheels to it.

Unfortunately, everything suddenly got caught in THE TIME WARP OF DOOOOOOOM!!!

Fourtunatly it was so small nothing could fit in it.

Unfortunately the Balrog was still at large.

Fortunately, the Balrog was distracted by chasing Mount Doom (or Zoom)

Unfourtunatly the wheels came of and he caught mt.zoom or doom.

Fortunately, the Balrog decided to drink the lava.

Unfortunately, he over indulged, there lying drunk and rather unconcious he rolled down the side of the volcano and had to start all over again.

Fortunately Frodo found the Ring.

Unfortunately . . .
 

. . . it was not really Frodo, but a disguised Gollum. He takes the Ring and puts it on. :p

Fortunately, it really wasn't the Ring it was a fake ring, planted by Frodo, he found in a Cracker Jack box. Frodo meanwhile has the real ring.

Unfortunately Gollum throttled Frodo and took the Ring.

Fortunately...
 

Fortunately what Gollum thought were Frodo's bloodshot eyes, were actually the eyes of Sauron in the guise of a Hobbit.

Unfortunately Sauron had taken the Ring from Frodo and tossed him into the lava.

Fortunately, Gollum bit Sauron's finger off and ran away with the ring. Sauron meanwhile was left rolling around on the floor shouting, "Not again!"

Unfortunately whilst Gollum was so happy at getting the Ring, he trips and falls down Mount Doom...rolling right into Gothmog (obviously I'm talking about Gothmog the Nazgul :p , not the the pink hairy guy).

Fortunately Gothmog freaked out Gollum so much that he ran into the hot lava of Mt. Doom, thus destroying the One Ring.
