Granted! Unfortunately the neoness of Gandalf's new color attracted the most unsavory sorts of people...tourists looking for the off-ramp to get into Las Vegas.

I wish Pippin was Bilbo's heir and had to take the Ring into Mordor.

Your wish is granted. However, Pippin gets so hungry that he eats the Ring along the way, causing his head to explode and the Quest to end.

I wish Sauron wasn't evil.
