The genies was confused by your question, and so gave you a random superpower (which happens to be self immolation, without the necessary fire immunity).

I wish that people had gotten me stuff for christmas

You get rotting garbage. Merry Christmas, you filthy animal.

I wish to become the genie.

 Congratulations, you're now trapped in a lamp. Unless someone lets you out, you'll be stuck there forever. If you are someday freed, you will be forced to obey the commands of whoever frees you. I hope you like 10,000 years of boredom followed by enslavement.

I wish for a Red Ryder Carbine Action 200-shot Range Model air rifle!

You shoot an icicle on top of your house, causing a ton of snow and ice to fall off your roof. You lose sight in both of your eyes.

I wish for wish

Granted. However, since you didn't replicate a spell and this is being treated as your wish, you become permanently unable to ever cast Wish again, rendering your Wish useless.

I wish that I could invent a clean, renewable, easy to manufacture source of energy.

Processing live babies gives you the power.

I can never wish again, due to a previous wish.

'And there's the game. Glad you all came out folks!' A genie starts walking around and shaking people' hands, turning them into different animals for forcing him into this game. Tsk Tsk tsk, you should have known he was a bad genie and would do this once the wishing stopped.

I wish for the One Piece!

You get a singular puzzle piece.

I wish for freedom from my existence as a genie.

Your now not a genie, however now one cam quite tell what you are now just that you smell weird.

I wish i had a new queen sized bed. That is not the size of an acual queen, but the bed size known as queen sized. And the bed wont crush me.

Due to a slight capitalization error, the bed went to the nearest map with a lowercase I on it.  And crushed the wall the map was on. 

I wish everyone on this site was fluent in English. 

Dragy dies.

Everyone on the site is now fluent in English.

I wish that dragy would come back to life,but with good grammar.

My gramer is good, but my typing and spelling are not. So no mater how good i talk, when typed, it turns to mush.

I wish for my phone to be repaired too a good condition, and for a reasonable price.

Granted, but the so called good condition is subjective and up to whoever is repairing the phone.

I wish I had "100 billion dollars"... real American dollars not fake dollars, and I did not steal the money...

You 100 billion dollars, but you are killed by your greedy children.

I wish for a singular, authentic, non-stolen American dollar.

Wish granted! Unfortunately, you get it in your D&D campaign, not in real life. Since America is nonexistent in that world, it is completely worthless.

I wish that people on this thread would learn how to use the following things properly...
- Spelling
- Grammar
- Punctuation
- Etcetera
...without causing physical, emotional, mental, or spiritual harm to me or anyone else.

I dare you to find a loophole to this.

They all use a dead language that you don't understand.

I wish for an authentic, non-stolen, gold coin

Gold coin? Sure!
It's authentic...
And you didn't steal it...
Unfortunately, it is the size of a quark and you are physically incapable of seeing it. Have fun with your authentic, non-stolen, quark-sized golden coin!

I wish for a puppy.

That is very ugly.

I wish for 20000000000000000$.

The police go after you for stealing that much money.

I wish my quark-sized gold coin was the size of a large spider

You want to make it larger, you say? Okay. It's now the size of a large spider...Oh, and it's also shaped like a spider. Oh, and did I mention it actually is a spider? Not only that, it's a female black widow. It proceeds to bite you. Enjoy spending three months in the hospital!

I wish for a cute puppy.
