Make a Wish. Have it horribly corrupted.

[spritey]

Granted. They can't die. But you don't have games for them anymore.

I wish for a shiny Chandelure.

[OranBerrySandvich]

Granted. It's so shiny, in fact, that it burns out your eyeballs. What, you didn't mean literally? Well, too bad.

I wish I could remember how soy sauce, yoghurt and cheese are made off by heart.

[spritey]

Granted but I cut out your heart. Now you don't know it.

I wish for a Victini that is not hacked.

[Sizacu]

Granted, it's at level 100 with probably one of the worst movests ever.

Currently wishing for some rice~

[ScottishFoldLover]

Granted, but as soon as I hand the bowl to you, you drop it on the floor.  The bowl shatters and the rice goes all over the floor.

I wish for a trip to an amusement park.

[Nightmare Eater]

Granted but the amusement park is destroy by a passing Zekrom when you were on a rollercoaster.

I wish for a corruption.

[spritey]

Granted. It's opposite day so you don't wish for a corruption.

I wish I had a Rice Krispie.

[ScottishFoldLover]

Granted, but instead of a rice krispie, you get crispy rice (uncooked rice).

I wish for faster internet.

[Kona]

Granted, but it gets too fast and then your ISP has to cut you off as you can't afford £1 Million a day bills.

I wish for a top hat.

[OranBerrySandvich]

Granted. It's the Scotsman's Stovepipe. You can't wear it in real life. You already have one. You accidentally craft it with the one I traded you. You get a hatless hat.

I wish for my writer's block to vanish quicker than a sandwich at a homeless hostel.

[ScottishFoldLover]

Granted, but Team Rocket steals all your pens/pencils, paper, and computer.

I wish for a glass of lemonade.

[Trekkie WhoLocked Fangirl!]

Granted but its a glass of cola...  I wish my storie characters were real

[OranBerrySandvich]

Granted, but Palkia isn't too happy about the spacial/dimensional disruption stuff. He puts them back and will do so whenever you put them here again.

I wish my thumbs didn't hurt from typing on my phone.

[Nightmare Eater]

Granted. Now your fingers hurt from typing on your phone.

I wish I made more sense.

[ScottishFoldLover]

Granted, but instead of more sense, you now make more scents, and even skuntank can't stand to be around you.

I wish that my neighbor's dog would stop barking.
