Scratch

Note: This game might not be suitable to younger kids as it can get pretty nasty but that's only if people are idiots and post stupid wishes. The game starts off with someone wishing for something. The next poster has to Grant the wish, all the while utterly destroying it.
Example:
Me: I wish for a horse.

Next person: Granted, but as soon as you look away for a second, it runs off and you never see it again.
I wish for World Peace!

Next Person: Granted but it blows up the next day.
I wish for.... blah blah blah



Anyways I'll start:
I wish for a new car!
