Corrupt-a-wish
I'm sure most of you have played this game. It's fairly simple. The person above you wishes for something, and then you 'corrupt' their wish and wish for something yourself.Example:
Person1: I wish for a pony
Person2: Granted, but your pony gets lost. I wish for a pillow
Person3: Your wish has been granted! However, your pillow is a man-eating pillow, and it eats your mother. I wish for a dog
And so on. I'll begin I wish for a purple hat.
