Rules for this game are very simple.
I'll post a wish, and then the next person grants the wish, but twists it in some way. The person who corrupts the wish can then make a wish, which is corrupted by the next person, and so on...
Example:
---Person 1: "I wish for all the popcorn I could ever eat!"
Person 2: "Wish granted! You are given a machine that produces infinite popcorn. However, it never turns off, thus causing your home to become unlivable."
START:
I wish for a cute fluffy sheep that will be my pet.
