In this forum game, the first poster makes a wish, and the next poster grants the wish, but causes something bad to happen as a result.
I.E.
Poster 1: I wish I was still on break from school
Poster 2: Granted, but you have a 20 page paper due in 2 days.
I wish I had a taco.
Let's begin!
I wish I didn't have to go to work tonight.
