Someone will wish for something, and your job is to grant there wish, but say something bad about it. It can be any wish; just be creative. :]
Here's an example:
Post:
I wish I had a new shirt.
Reply:
Granted, but it costs you $100.
After you grant a wish, you must then post your wish below it for the next person to answer. I'll start us off.
I wish I lived in Canada.
