This is a fast two-sentence game from a forum long ago in a community far, far away. I will wish for something. The next person responds with "Granted, but (something that ruins the wish). I wish for (something else)" and it continues from there.

Example: 
First post: I wish for a new car.
Player 1: Granted, but it breaks down the first time you drive it. I wish for a million bucks.
Player 2: Granted, but (etc). I wish for (etc).

You can make the responses as weird or ridiculous as you want, but don't meta game, i.e. "Granted, but this game is dumb. I wish someone would make a fun game." Keep it simple, keep it moving, have fun!

I wish for a job.
