Make a Wish. Have it horribly corrupted.

[Backsauce]

Granted, but you will get horrible grades in that class all your life and all of your classmates and your teacher will hate you.
I wish my wish wouldn't get corrupted.

[Spriter]

Granted, but your words failed to decieve me and it,well,opened a black hole and destroyed you.

[Skyler and Blazer]

Granted. Your no wish became a giant lava monster that ate your family and burned down your house.

I wish I didn't have scoliosis.

[Backsauce]

Granted, but everything and everyone you touch now has it.

[spritey]

For not having a wish, a Castform hits you with an Ice-powered Weather Ball and you turn into a cloud.

I wish I had a green Golbat that eats Chikorita salad along with Moomoo Milk and Mightyena steak.

[Backsauce]

Granted, but once you look at them they die.
I wish for a wish

[spritey]

Granted, you now wasted that wish.

~ wasted ~

=P

And I wish for an orange-scarlet-red Krabby.

[Backsauce]

Granted, but your crabby just turned blue and died...you can't even look at it because it disintegrated and is now dust in the wind.
I wish for a wish that couldn't be wasted, corrupted or damaged in anyway. 

[spritey]

Granted, you wasted your current wish to make sure your other wish couldn't be wasted.
I wish I was Ice Beamed by a Glalie and frozen and whatever else the next person throws on me.

[MzLuluZombi]

Granted. You are ice beamed by a Glalie and you are frozen. And then you are crushed into a lovable Companion Cube and due to it being part of the standardised test, you are required to be thrown into the Aperture Science Emergency Intelligence Incinera - HA, I'm kidding, you get thrown into a volcano. Oh well, at least you'll thaw before the corrupt part comes in.

I wish for a blanket.

[Liam]

Okay, but you're only allowed it for half a second.

I wish for more  usage on the forums.

[Webby]

Granted, but the afro gets shaved so he's just a dude wearing cheap shades.

I wish I had a hot chocolate.

[Liam]

Yes, but you're not allowed to drink it. Too bad. :[

And the shades ain't cheap!

I wish for cool shades now. :]

[spritey]

Granted, but you were standing on a bridge enjoying the fresh air with your shades when your cool shades accidentally slipped out of your hands when you tried to put them on and fell in a river and tumbled down a waterfall, hit a rock, got eaten by a huge bass, coughed up and washed up on the riverbank and now they are broken, dirty, wet, sandy and completely uncool.

Ultimate wish corruption lol

I wish for a wish

[Backsauce]

Granted, but you just lost your wish cuz i said so!
I wish for the opposite of what i wish for!
