Unfortunately, with time going backwards, Legolas moved in on Aragorn again.

Fortunately, as the time spell sluttered out, Legolas approached Aragorn again. This time, Aragorn declared his undying love for Legolas.

Unfortunately for Legolas, Aragorn was only kidding
and had Rangers take Legolas back to daddy
(who quickly deprogrammed his heir).

Fortunately, the Nazgul came riding in and everyone except Gandalf fled.

Unfortunately Radagast revealed himself uncloaked
(being into naturalism through his committment to
nature study) which prompted Gandalf and the nazgul to flee
to the safety of the Far east of Middle-earth.

Fortunately, this quickly became unnecessary when a dragon ate Radagast.

Unfortunately, this inspired Gandalf and the nazgul to go
50-50 on turning Orthanc into a luxury condominium.

Fortunately, Merry and Pippin showed up in tme to talk Gandalf out of it.

Unfortunately an undiscovered palantir broadcasted all of this to Sauron and he went into a fit of rage and destroyed Mount Doom.

Fortunately, Sauron had bought up property in
Tharbad and made a fortune charging tolls for
Elassar's messengers going from Eriador to Gondor.

Unfortunately, the messangers soon discovered a different route, and never has to pay his tolls again

Fortunately Sauron had invested in Lembas shares and the returns from the Mirkwood Stock exchange paid for the rebuidling of the death star... i mean, mount doom. He invited everyone to the grand re-opening, including Galadriel.

Unfortunately, nobody that he had invited showed up.

Fortunately, a very hungry Shelob (who it turned out had
amassed a fortune from her leveraged purchases of land in
Ithilien and the Lake Nurnen farms) agreed to partner
with Sauron and Elassar in New Barad-Dur Towers.

Unfortunately, hurricane Sandy got sucked through a magic portal into Middle-Earth, and blew Elessar far, far, away, depositing him at the doorstep of Bag End.

Fortunately, Elessar had such extreme fitness that he simply ran all the way back

Unfortunately, he fainted from exhaustion when he returned.

Fortunately Arwen was there to, ah, revive him.

How did my favourite thread die?

Unfortunately, Arwen revived Elessar as a leprechaun.

Fortunately, this was hilarious for all involved.

Unfortunately, after the novelty wore off, nobody had any idea how to turn Aragorn back.

Fortunately, Ungoliant did mention tales of a Leprechaun-elixir in Mount Gundabad

Unfortunately, she could not remember how to contact the man who made it.

Fortunately, no MAN made it...a woman did (major
plot twist :) ) Okay, she was aided by a wee hobbit.

Unfortunately, said woman was dead, as was the hobbit who had assisted her, and they had taken their secrets with them to the grave.

Fortunately the grave was a Barrow-wight's, which was visited
every St. Patrick's Day by Tom Bombadil who occasionally needed Lephrechaun's
elixir for a problem with interacting with Goldberry... ;)

Unfortunately, there was no elixir left when the grave was found.

Fortunatley, that was only because Tom Bombadil stole it all and had a huge store of it up a tree.

Unfortunately, said tree was an extremely curmudgeonly willow-tree and Bombadil had laryngitis, so couldn't sing his roots off.

Fortunately, Legolas had enough influence over nature that he was able to soothe the tree into stillness.

Unfortunately, the elixir was slightly past its expiry date and so had some unpredictable side-effects. For instance, whilst Aragorn stopped being a leprechaun, everything he uttered from now on was in sung Bombadil couplets.

Fortunately, this gave Arwen an excuse to ditch the hu-man and
start a torrid affair with Tom (she had a thing for older males, and
a child like Aragorn...).

Unfortunately, Goldberry came out at that moment, armed with a rolling pin.

Fortunately, Bombadil wasn't actually in a relationship with Arwen, it was purely one-sided.

Unfortunately, Arwen then boiled Goldberry's pet rabbit.

Fortunately, boiled rabbit was a delicacy at the Prancing Pony
so Goldberry made a tidy profit.

Unfortunately, the rabbit hadn't been filleted, and several of the guests nearly choked.

Fortunately, Bree's excellent NHS covered the ill guests.
(Unlike Bree's colonial spinoff, The Shire, all residents and
guests received universal health care coverage. The Shire's
more conservative ethos felt it was each hobbit's responsibility.
This worked out well for upper class hobbits like Merry and
Pippin, Sam and The Gaffer...not so much). :(

No doubt there's some kind of moral there. :)

Unfortunately, Golberry refused to reimburse the guests who demanded their money back after the disasterous dinner.

Fortunately everyone went to The Prancing Pony for a catered dinner by Farmer Maggot and his wife of mushrooms, bacon, and beer, followed by some of Goldberry's famous tiramisu.
