Fortunately, Morgoth also landed in Mount Doom

Unfortunately . . .
 

. . . he was wearing lava-wings.

Fortunately, the lava wings were no use as someone had cunningly taped them together.

Unfortunately, Gandalf thought Morgoth was and Eagle and decided to ride him.

Fortunately, Morgoth believed he was an eagle, and with Gandalf on his back he went running off a cliff.

Unfortunately, he tore the tape off of the wings and did, in fact, fly.

Fortunately, Sauron wasn't much pleased with them disturbing his afternoon nap, so he fried Morgoth with some lightning (Gandalf being immune of course because of his cloak's amazing reflective properties)

Unfortunately, Gandalf wasn't wearing that cloak today.

Fortunately, this morgoth fellow rather like being zapped now and again my a good bolt of lightning.

Unfortunately, this was not one of those days, and Morgoth fried Sauron for attacking him. He kept Sauron alive, however, since he was happy Sauron was on the right track and using his powers better. Gandalf had also survived since Sauron's power was not all it was made to be.

Fortunately Captian Obvious was around to point Gandalf's predicament out to Aragorn and the others

Unfortunately, he showed up just as you said that.

Fortuantely, Gandalf was rather annoyed with Captain Obvious, and suddenly a hoard of Lego Lovers bundled on the elf. A satisfied grin spread across Gandalf's features.

Unfortunately the hoard of Lego Lovers only appeared to be Lego Lovers....they were actually a hoard of Ninja Wizards sent by Saruman.

fortunately, they were only masgarading as ninja wizards. in reality they were just lego lovers and, asisted by our good friend zack, they built like crazy and got gandalf out of his predicament (whatever that may be...).

Unfortunately, Gandalf didn't want their help and he zapped them into Ninja Wizards.

Fortunatly, Perky had to study for a history exam tonight, and didn't have time to make an unfunny comment.

Unfortunately, Aragorn decided to help Perky resuling in him getting the line of kings all wrong!

Fortunately, Perky decided that it was better he didn't have tutor and he continued his studies in peace.

Unfortunately, with all the distraction caused by Perky, everyone forgot the real problem....Theoden needed a bed time story before he could go to sleep!

Fortunately, that event was fifty years ago and a bedtime story was made. Luckily, it was also good.

Unfortunately, this meant that Théoden had slept through the battle of Pelenor and so the Witch King had not been killed and Minas Tirith fell.

Fortunately, the ring was still destroyed.

Unfortunately, the ring that was destroyed was Vilya

Fortunately, Vilya was the One Ring that needed to be destroyed, not Sauron's "One Ring"

Unfortunately, Gollum knew about this, and saved the true One Ring, Vilya, from destruction without anyone noticing.

Fortunately Elrond confessed to Figwit that Vilya was the true One Ring after he was waylaid by Orcs on his way to an Overprotective Fathers convention.

Unfortunately, Figwit was a traitor and told Sauron about this through the palantir he had found in the ruins of Weathertop.

Fortunately Figwit died a horrible death by the black beast of aghhhhh and nobody thought about him ever again

Unfortunately, they did think about Johnny the Stinky Balrog.

Fortunately, Johnny the Stinky Balrog was doing some celebrity reality T-V show (Big Brother: Celebrity Tramps edition) and lost all credibility.

Unfortunately the show fell through and Johnny came back to M-E

Fortunately, the reality TV show was a big hit in the Undying Lands (can you blame them? I mean... Undying...), so Johnny was called back again.

Unfortunately, the show could only be seen on Thursday evenings, which were the Undying Lands' official Bowling Nights.

Fortunately Arwen found Vilya.

Unfortunately, Arwen turned into a grotesque Gollum looking creature and Aragorn divorced her.

Fortunately Aragorn had a terrible golfing accident and was blind, thus he took arwen back

Unfortunately, when they were together they were so discustig to look apon that the people of Minas Tirith cast them forth and they went to live in Mordor.

Fortunately Aragorn was able to take Vilya from Arwen.

Unfortunately, all Vilya did was bring the horrid scents to him through conjured winds.
