Horkus Porkus! You now have a Brake Caliper.......for the wrong car.

I wish I had some pie!

You get a mud pie thrown in your face.

I wish my farts smelled like fresh-baked cinnamon buns.

Everytime you fart a Cinnamon bun comes out.

I wish I had a new bike.

YOUR BIKE HAS FOUR WHEELS AND ALUMINIUM FOIL ALL OVER IT IN THE SHAPE OF A PORSCHE. Actually, that ain't half bad...

I wish I had a Klondike Bar.

SHAZAMOFOOOOOZOOOO!
A clondike bar appears in front of you. However its a cheap Chinese rip off. Chocolate is made from tears of little children and the ice cream come only in mint ice cream.

I wish I was just a little bit taller.

ASDF;LKJ You become taller. Just a little bit. Like, 0.00000000001in taller. CONGRATS!

I wish to do the fork in the garbage disposal.

FWOOM
You did it. Your pelvis isn't feeling too good.

I wish I were more clever

Suddenly, a disturbance in the space time continuum, and a giant flash. Sitting at the end of the two flaming tire marks... was a cleaver. i dont even

I wish I could see dead people

And Suddenly.......THE ZOMBIE APACOLYPSE!!! The dead rise to feast on your tender, sweet flesh.

I wish I could fly.

(What flesh? X3)

O: Holy smokes. YOU CAN FLY! Oh no... TERRORISTTTTSSSSSS!!!!

I wish I had more money for car parts.

You find a bag of stolen money on the sidewalk. Too bad the dye pack already detonated inside making the money worthless....

I wish I had a sub.

Essentially, that happens.

I wish I had FAIRY GODPARENTS!!1!1one

Congrats. You now have two prancing, gay godparents who have no magic talent whatsoever.

I wish to get that which I've always wanted most!

You get EXACTLY what you wanted. You, however, realize that having this wish come true has only left you with the same empty, sad feeling you had before only worse because you didn't earn it nor does it leave you with any purpose. You have nothing left to strive for now that you have it.

I wish I had bigger breasts!

GRANTED! But unfortunately they're massive, and located on top of your head, and they're saggy, so they flop over across your eyes from time to time.

I wish Firefly was back on.
