Be careful what you wish for...

[Eorl of Rohan]

Ooh, my darling puppy imploded! +goes after Hook with a knife+

I wish the eye of Sauron could see better

Your wish is granted! Eye of Sauron now reaches past the infinite stretch of the universe, in fact, he sees everything, so much that the receiver for sensory perceptions are flooded with images so much that it is impossible for him to remember anything he sees for more than a second.

I wish Hurin was the one who said 'Now comes the night'.
