You are now all "Being John Malcovich"ed inside the head of a small colorful viper snake. Your moving back and forth, thraveling through the forest when you come across an evil animal squatting on your land. To protect yourself you strike, infecting the victim with powerful venom. That victim is your human body and you can feel the powerful neurotoxins flowing through your veins. Congratulations, you just killed yourself.
I wish a tree didn't fall and hit my car last night.
You can! It is just too big for your little head to handle. Your brain explodes. On the downside you can't tell anyone about how awesomely huge the universe actually is. On the bright side, your dead and so noone has to hear exactly how rediculously huge the universe actually is. (No offense intended.)
I wish to be unable to hurt other people's feelings when I talk.
It does. Rain, then get sunny, then rain, then sunny, then rain, then sunny. Infact it changes every 10 seconds. In a blinding fury the seasons come and go, only raining and sun shining. No snow anymore, just rain and sun. No time to adjust, just rain and sun. People start having to wear raincoats all the time even in the hot sun. Always pruny hands and then the crops start to die off. The oceans lose their salinity and the fish die. Then people begin to starve. Congratulations, you just killed of the human race because you didn't like overcast days.
Unfortunately "they" discovered that you used a wish to get the perfect scores. Word of your cheating spreads like wildfire. You're fired from your job and will never be hired by anyone ever again. Eventually you end up homeless and destitute wishing you had been happy with that B+ but now have now means of getting back to the Inn to make the wish.
I wish worms would wash away the woes of Washington(DC)
But last time you thought it up you realized a key flaw in your plan-- that it would only be a matter of time before Grugg ate the cage as a prelude to eating your entire house.
Too bad your didn't remember that this time around, because now Grugg is free and you're without a home.
I wish people wouldn't end up homeless every time I corrupt a wish.
