They were! But everybody got so sick and tired of mushrooms that hobbits started eating twigs, that turned them into a big glowing mass that fell right down through Arda, into the 74:th dimension.

My toe wishes that she would be reborn as Aragorn.

Your toe's wish is granted. Your toe is now Aragorn. But he develops an ingrown face and has to convalesce in Rivendell and doesn't become King.

I wish that the Barrow-wight was a good guy.

Granted. He was a good guy. In fact, when Frodo was lost on the Downs the Wight called to him and said "Here I am!" but Frodo was too afraid. Then Frodo fell over and the Barrow Wight took him back to his Barrow to make sure he was all right. When Frodo woke up, the Wight sent a little hand creature to offer them tea and cakes, but the hobbit was so afraid he attacked the hand.
In a last ditch effort to cheer Frodo up, the Wight sung the only song he knew all the words to, "Cold be heart", and old Barrow Downs favourite. But this only made matters worse and Tom Bombadill showed up and threw him out of Barrow and home.

I wish Sauron smoked a pipe.

Sauron did smoke a pipe! In the middle of the Siege of Barad-dur. He claimed it to be his "pipe moment" and commanded peace. All the baddies retreated and Elendil, Gil-galad and Isildur joined Sauron smoking their pipes. After a long chat and a few too many pints, they desided that Sauron wasn't such a bad guy after all and asked their psychologist Izindibolgdam to help Sauron. Izindibolgdam listened Sauron and desided that Sauron's problem was the lack of calcium. Sauron was very relieved that this was the case and even paid Elendil for his kindness by giving them the largest projector in Arda's history.

Happy end!

Your wish is granted. But pain makes him mad, and he's a better fighter when he's mad.

I wish Denethor hadn't killed himself.

Granted! But without his suicide someone else had to step up and kill his/herself. In the end the weight fell on Aragorn and the last heir to the throne of Gondor died.

I wish wargs had been used by Men and Elves.

Granted. The Wolfus Demonicus, or the Warg, primarily feasts upon halflings.

I wish the people of Middle-Earth realized that Sauron wasn't that bright.
