The world is struck by a food crisis, and the only way to stop it is for the wish-granting genies to feed the world. Unfortunately, nobody can wish for food anymore. Everyone turns to cannibalism, and guess who they eat first?
Your family.
Then your friends.
Then all the people you ever met.
Then all the people you ever saw.
Then everybody within 50 miles of you.
Then they chain you up in a dark basement and leave you there forever.
What, did you expect them to eat you? The food crisis was solved while they were doing all that, they just did it out of spite.
EDIT: Ninja'd. Mine was better though
LazDude: You get a picture of a vodka martini, which is shaken rather than having a spoon viciously ripped through it. You then get forced to eat the paper for no apparent reason by an alien which abducts you.
I wish for an extra day in the weekend
