Corrupt a wish

Granted, but your moniter is tiny, rendering the computer useless.

I wish I had no homework

Granted but you get tons of take-home school work instead.

I dont care if it hurts. i wanna have control, I want a perfect perfect body, I want a perfect soul.

Granted! You're still a creep, you're still a weirdo, what the hell are you doing here? You don't belong here.

I wish I had another pink duct-tape wallet.

Granted, HOWEVER, your home burns to the ground with both your old and new pink duct-tape wallets in it, and your so depressed you commit suicide. In addition no one cares when you do kill yourself, the world is a better place for it, in fact.(how's that for a ruined wish?)
I wish I could on public television also, me and my big Metapod had to be watched by everyone on earth.
