Make a Wish. Have it horribly corrupted.

[OranBerrySandvich]

Granted. It's not poisoned, it's the rigt temperature, there's enough of it for you to be content with, and you can eat it.
Unfortunately, that was MY apple pie. I beat your face in for taking my apple pie. You die.

I wish that every villain was lemons.

[spritey]

Granted. But after that they were limes.

I wish for unlimited wishes.

[Trekkie WhoLocked Fangirl!]

Granted but that was your last wish...    I wish for chocolate cake

[spritey]

Granted. I steal it from you and eat it.

I wish for a 3DS.

[Gusparce]

Granted, its at the bottom of that volcano.

I wish for something that does not exist.

[spritey]

Granted. You get a real live shiny Zangoose. It claws you in the throat. You die.

I wish I had a clean mansion that will not get destroyed, that I will not get bored of, and it's not haunted.

[Skarmory8]

Granted. It doesn't get destroyed, it's not haunted, and you never will get bored of it. That's because you were run over by a JCB while it was being built.

I wish for a cookie

[Sizacu]

Granted, but it's quite moldy. c:

I wish for a wireless keyboard.

[Trekkie WhoLocked Fangirl!]

Granted, but it dosn't work        I wish for my violin strings not to be broken :-(

[spritey]

Granted. Everything else in your violin is broken except the strings.

I wish for a cute groundhog that would not bite, would not carry diseases/ticks/rabies/fleas/etc., would not do anything bad in my house, would be allowed to stay, would not poop or pee, would not die, and would not run away. =P

[Nightmare Eater]

Granted so now all it does is lay there, losing various organs and body parts without ever getting diseases. While it can't die, you have to look at its awful body everyday because it can't runaway. Plus it hates you because you caused this but it can't bite or do bad things to your house so it just lays there angrily wishing for your demise. How evil.

I wish for a tuning.

[mewz2cute(:]

Granted. But that was the last tuning you will ever receive.

I wish for snow!

[yukithewhitewolf]

Granted but some idiot peed his name in your lawn.

I wish I had all the powers of Sub-Zero

[Nightmare Eater]

Granted. You're frozen.

I wish for 1 year old milk.

[yukithewhitewolf]

Granted you got 1 year old "Goat" Milk
I wish for one of every Yugioh Card in existence.
