You get the treant, but it is poorly potty trained and pees all over your gear. The smell never comes out.

I wish for a flaming sword.

you burn your hand picking it up.

i wish i would stop procrastinating, and finally start writing this story i have been putting off.

 You stop procrastinating with a new found fervor for life.  You write your story-- and some.  It's a best seller, in fact.

Your whole life seems different.  The emptiness you felt is gone... it's incredibly satisfying at first.  You've never kept your house this clean-- never been cheerful when it comes to meeting so many new people.

Your procrastination is destroyed by your drive.  Your ability to procrastinate is gone, and spurred on with your money from the best selling story you aim to change the world.

You spend years dedicated to this task.  People come to regard you as a saint.  You become famous the world over for your heroic deeds and good doings.  You become grossly rich in a way that people would normally despise, but when they see the wholesome way you give it back they feel inspired to do the same.  It's incredible really, with your drive you change the world.

You approach your 80's.  You're near death now-- and there's nothing you can do about it.

You die sad and alone, never having been satisfied with your situation again.  There was always one step further you could reach.  One more goal out of touch.  Maybe you could have ensured humanity wouldn't destroy itself.  Maybe you could find a way to get your drug-addict of a child to finally quit and pick their life up again.  There was always something, life was never good enough for you, and not once for that entire period of drive could you define meaning or happiness from the emotional emptiness that you were driven to fill.

I wish for a hat.

Unfortunately, the hat is really uncomfortable and totally not your style.

I wish that something bad would happen to me

You die.  Painfully.  Over a period of about 10 years. 

Then you're brought back to life.  So you can do it again. 

This continues until you have no will left.  No mind left.  No spirit left. 

Then, finally, you're ready to be a cultist of a Great Old One. 

I wish for arrows and an archery range. 

you are the target on the archery range, and you did not wish for a bow, so people are just throwing arrows at you.

I wish for something romantic to happen.

Unfortunately, your wish is granted a way that fits the literal wording of the wish, but perverts the intent in such a way that I cannot come up with because I am bland and unoriginal, due to having no mind.

i wish for nothing, because as a mindless servant of The Great Old One, I have no need for wishes.

You become one with the nothingness of the void.

I wish for the beginning of the end times/ the apocalypse.

Dnd is now outlawed.

I wish too have 33 new pairs of socks that fit me.

Again, they fight you.

i wish for my sanity back

you are now so sane, that you seem insane.

i wish for a comfy chair for the genie, he/she must be tired, and i am not too be the chair.

the appears inside you. ouch.

I wish for a singular chicken femur.

the femur is scared. you could say, a chicken.

i wish for a blue pocket watch.

Your pocket on your blue jeans can now tell the time. However, when you bend over to look at it you break your back.

I wish for a tree.

its a frail bonsai tree, you break it.

i wish my back was healed.

It's healed, by having your brain's life force transferred into it.

i wish for some cash.

You find a thieves cache. And your now hunted because they dont want anyone to know the location of it.

I wish for some gentle rain showers, that wont flood anything.

Granted but the gentle showers don't seem to let up until everything in the area is so over saturated all the plants die.

I wish I could use true polymorph at will; never get stuck in a form, and always be able to return to my original normal human form.

You can use turn polymorph on people named will, and nobody else.

I wish for unlimited money to be in my bank account, but It won't crash the economy or get stolen.

They beleve you too have stolen all that monney, you are imprisoned.

I wish for a harmonica, and a "how to play the harmonica" booklet.
