I wish Gandalf was dressed as a clown during the siege of Gondor

Your wish is granted. But the clown suit didn't last long,because Ganndie could't find a suitable hat to match,and he thought the suit made is beard look weird.

I wish that Aragorn snorted like a pig when he laughed,which he would do alot!

Granted! Sadly, Arwen was Jewish and pigs are not Kosher (edible according to jewish law). Yet Arwen had a secret craving for pig meat, which was made worse by Aragorn's constant pig-snorting. To make a long (even for elvish standards) story short, she dumped him on a rainy day on the steps of Minas Tirith.

I wish that when Arwen goes to Gondor after the end of the war of the Ring, she has gained LOTS of weight

Lots of weight, you say?

Does a tonne sound about right?

So Arwen shows up in Gondor with an extra tonne. However, Elves don't getter fatter when they get heavier, merely denser. Therefore, Arwen LOOKED the same, so Aragorn didn't notice anything- until their wedding day, when she jumped into his arms for him to carry across the threshold of the citadel.

It was a disaster. Aragorn broke both arms, as well as his back, rendering him a paraplegic- thus leaving the care of the realm to Faramir. Arwen was too embarrassed to ever appear in public again. Elrond and the other Elves were mortally embarrassed as well, disappearing in the night, and thus not allowing Elrond and Arwen to have their poignant good-bye.

I wish Galadriel had a mustache....

Grossly granted.

The Lady Galadriel now has a mustache and upon seeing her the Hobbits have the great idea of starting a Middle-Earth Freak show, including the bearded elf, the greasy king, and Gimli. Of course with the Lady's facial hair, Gimli falls even more in love with her. They run away from the freak show together and elope, one moving to Bree where they can live in peace.

I wish Thorin hadn't died in battle.

Woosh! Your wish is granted! Thorin doesn’t die in battle. Instead, he dies of alcohol poisoning at the party the next day. Bilbo is told he died in battle.

I wish Théoden's horse, Snowmane, had eaten the Witch King's steed.

[narfforc]

I wish it was real, apart from the Elves, the filthy Tarks, oh and them tree thingies, and that damn meddling wizard, not forgetting them little rat-men from the north. But above all, I wish that the nice Mr Sauron was still alive

It had been a harsh Winter in Rohan, no food for the people, much less for the horses... yet they rode off to battle and to the aid of their allies. The Witch King appears in front of Theoden King and Snowmane seizes the oportunity. While being starved by the famine, the horses of Rohan had learned to eat birds and such little animals, so finding the HUGE animal the Witch King was riding on Snowmane could not stop himself from taking a bite. Then another. Then the other horses came in.... by the end of the day, it was actually Snowmane who defeated the Witch King (not a man, so it's still possible). Unfortunately for Theoden, Snowmane then decided to roll over and lay on his back as he was pretty satisfied and crushed the King under him.

I wish Legolas had been named High King because of a mistake by Gandalf

I wish Legolas had been named High King because of a mistake by Gandalf

Your wish is granted. But when he announced that he was engaged to Mary-Sue his royal council gave him an ultimatum: either cancel his engagement or abdicate. Legolas abdicated and moved back to Mirkwood with his bride. Aragorn became the new High King. But King Thranduil disinherited Legolas, who moved to Ithilien. He sailed to the Lonely Isle twenty years later after Mary-Sue was killed by a hunter who thought she was a wild cow.

I wish that Turin hadn't married his sister.

[The Elf-warrior]

I wish the three Troll's mothers had appeared in The Lord of the Rings for revenge!

Your wish is granted. They came to the Barrow-downs but the Barrow-wight sent them away because he hated Trolls.

I wish that Pippin was an inveterate practical joker.
