I saw this in a different forum and thought it was pretty cool. You just make a wish, get it granted, but also corrupted.

ex:

Person 1: "I wish pokemon would be real"

Person 2: "Granted, but they disobey you and attack you. I wish Snorlax could fly."

Person 3: "Granted, but it's so fat that it would block the sun and cause another ice age".

Got it? Good.

I'll start....I wish that Misty would travel with you.

Granted.... But Misty will take out an automatic AK-47 and blow your brains out.

I wish I had a perfectly obedient Rayquaza.

Granted...but raquaza would sometimes just get confused and try to hit you with hyper beam

i wish i had a cool obediant totodile

Granted, but it would evolve into a Feraligatr and run away.

I wish Oak would battle Agatha.

Granted, but it's a sword fight, rather than a Pokémon battle.

I wish I were the Pokémon League Champion.

Granted, but I'd take your title with my Nidoking.

I wish you could go to Johto in this game...

Granted, but then Arceus overruled me.

I wish you could drive a suped-up Lamborghini with nitrous oxide in the Pokémon games.

Granted, but the noxius fumes from the car's exhaust poison all the pokemon, leaving all of humanity on the brink of destruction.

I wish Ash would admit that he actually likes May or Misty.

Granted but they slap him and walk off.

I wish Nurse Joy would heal tired humans.

Granted, but she charges a lot of money for these services.

I wish for a million bucks Mudkip never existed.

Granted, but every single 5 year old would cry at the same time and somehow cause tidal waves.

I wish I could run a pokemon day care.

Granted but no-one ever visits.
I wish I had 99 rare candies right now.

Granted, but they're 10,000 years old and so they actually reduce a Pokémon's level.

I wish all 493 Pokémon could be legitly obtained in one game without trading or events.

Granted, but that game will come out in 79 years.

I wish that there was an officer Jenny in this game.
