Wish Granted, But you read your moms mind and you find out you were a mistake so you commit suicide.

I wish i could play guitar like Slash

Wish Granted, you rocked out so loud that your ears burst and you couldn't hear your music forever.

I wish I had mad dance skills.

 Granted, You get thrown into a Dance Dance Revolution arcade game and are forced to dance everytime somebody throws a quarter in.

I wish for a In n Out Double Double with just the meat and bread.

Wish granted but the meat are all soiled and the bread have  molds.

I wish that my wish, will be there wishes too...  :p
