Wish granted, but you get challenged to a guitar off and lose and die.

[P.S. Just go pick up a cheap 100$ (whatever that is in Euro's ) and find some simple songs, and look up videos on how to play it or tabs (www.ultimate-guitar.com I believe has some good tabs, I use them) and just practice. I've done this and now after 1 1/3 of a year later, I'm moderately good at it (and I'm going to keep getting better the more I practice)].

I wish my parents would allow me to buy a drum set and not make a big deal out of the noise it will make.

Wish granted. Your parents couldn't care less about the noise, but the Police do

I wish I could beat the living shit out of every guy I see treat their girl bad without consequence.

Wish granted, but you accidentally treat a girl bad and keep beating your self up.

I wish I could think of a better wish.

I have a guitar but my fingers are too short for chords :'( I just suck regardless of practice

Anyway...

Wish granted but your wishes are too good and nobody can turn them corrupt.

I wish I was super-uber talented at everything.

I think if my fingers can work with chords, yours can. I have really small hands, and you're a lot older than me.

Wish granted, but you get some many haters that they assassinate you.

I wish I was better than everyone at guitar!

I can barely reach the top string when I try and hold a chord with my middle finger, I just don't have the fingers to play guitar, hence why I'm a graphic artist not a musician xD

ANyway...

Wish granted but you become so good that all the failed guitarists murder you :3

I wish I had some sushi...

Wish granted. You choke on an eye and die.

I wish it were cooler outside...

Wish granted, but the world goes into an ice age and everyone dies.

I wish it would snow in Florida!

Wish granted but it snows all year round and Florida becomes the new Canadia eh.

I wish I could sing.

Wish granted, but you get some many haters you get assassinated.

I wish I was in a band.
