You get your mangos... but they're rotten, and you are slowly crushed to death by the sheer weight of too many mangos.

Alternatively, the mangos appear nice and ripe. One by one. Inside your stomach. Until you split open and don't die... immediately, that is.

I wish Pokemon were real, and non-lethal.

They become real but they destroy the line of existence between the video game galaxy and reality causing the whole universe to go into a giant vortex of doom and erasing humans from existence and make pokemon replace humans.FOREVER.

I wish Smasherlink would come back

Your wish is granted, but he is instantly banned by Ramsey, and the world is happy. Oh- wait, that's good... You are sorry you can't have a yaoi scene with him and kill yourself.

I wish Thai would make a new Spam Chooses Their Own Adventure.

Thai makes a new Spam Chooses Their Own Adventure, expect it's the same as the first adventure except with a different main character.

I wish that there was a male Disney Princess. (So many things are going wrong in my head right now)

All the kids in the world become 'confused' and the world is plunged into eternal chaos.

I wish that there was coffee on my table. And it tasted nice.

Too bad it isn't in a cup. :/ That was an expensive table.

I wish all wishes were as easy to corrupt as the one I just did.

They are easy to corrupt. Every wish in the world is easily corrupted causing death, rape, and s*** to blow up.

I wish for a hat.

The hat turns out to be cursed and permanently fixes itself to your head.
It looks so ridiculously stupid that everyone human being you try to communicate with becomes a dribbling idiot and trying to use words with more than 3 syllables hurts their minds.

I wish my cold was gone.
I wish my internet was faster but not fast enough to outrun me.

You are slower than the speed of which your internet was, and since you wished for it to not outrun you, it slows down and you suicide because you hate slow internet.

I wish that Syntax errors could be erased from all reality.

They are erased along with all of the computers in world !

I wish that I had a Rayquaza loyal to me.

The Rayquaza now only obeys the commands from a guy named "me".

I wish I had a wish to be corrupted.

You have a wish to be corrupted, but you are banned from MG, and your computer is gone.

I wish I was actually good at Mafia.

Granted, but no one else wants to do it anymore.

I wish Plok got a new game.

Plok hates his new game ragequits and suffers a mass aneurysm from the game.
I wish I was a successful writer using TV Tropes as a launch pad to start the writing.

You become very successful. At first. Unfortunately for you, TV Tropes ruins lives; you become so hopelessly addicted to it, you forget to sleep and eat. People that care about you have to forcefully remove you from your computer and/ or terminate your internet. You die a slow, pitiful death drawn out by months of insanity. You spend your last days babbling maniacally about unusual dysphemism and retconjurations.

I wish there were more tropers on the MG forums.
