Grant a wish.

[Guilmon and a shotgun]

Granted, they're all bots. THOUSANDS of them!

[The Big Bad Rav]

and GMSG...

I wish there's a wish!

[ParkerXD]

Granted, the wish is there but can never be granted

I wish that everyone became happy and there was world peace.

[RaptorSyn]

Granted, A neurotoxin was released into the air, activating the chemicals in the brain that produce happiness that also is a degenerative, slowly decaying the mind and the body.
Everyone dies+happy=world peace

Oh I wish I were an Oscar Mayer wiener.

[The Big Bad Rav]

granted, but a giant comes to eat u with a bun

I wish I didn't have a hairball in my throat

[Crimson Fox]

Granted. *casts a spell, causing the hairball to disappear* You're cured. That will be $5000. Magical materials aren't cheap, you know.

I wish for a twin sister.

[ParkerXD]

Granted, You can never meet her though.

I wish to command the power of the sun with my mind.

[Crimson Fox]

Granted, but in the two seconds that you turn off the sun, the Earth freezes over and everyone dies. The end! :P

I wish for cool, tasty drink.

[RaptorSyn]

Granted, but everytime you try to take a drink, the refreshment lowers from your lips.

I wish that I could control the elements!

[Crimson Fox]

Granted, but soon grow out of your control, causing wide spread natural disasters. D:

I wish for more muscle.
