Corrupt a Wish!

[The Vision]

I saw this on Myth-Weavers and I liked the concept. The premise is that you grant the previous poster's wish, but in a way that makes the wish undesirable. Then you post your own wish.

For example:
"I wish I had a cookie."
"Granted. It's made out of rubber."

I'll go first. I wish my ear didn't hurt.
