You can, but when you just learned it all you suddenly forget everything you know. I wish I had a magical machine which would code for me (I do have one due to penguin magic)
You get your magical machine, but it doesnt code ; it just spews out white paper instead. I wish for epic stuff.
You get your Nutella filled bagel but Ferrero got the recipe wrong so when you bit into it, There were only the plain; dried out hazelnuts. =) I wish for BuildCraftia to be online.
You get more DTC maps, but somehow they corrupt due to a bug and you can't play them anymore. I wish for a cubic meter of gold.
Instead of gold, you get a cubic meter of slime, infesting your house and ultimately killing you. I wish for potatoes.
(Please, read what it says on the OP: The wishes must be granted, but then something happens) You get potatoes, but as you didn't specify how many you get a billion potatoes killing you by suffocation.
You get cheesecake, but a cheesecake eating monster appears and eats the cake and you as well. I wish for better skype.
You get a pet dinosaur, but it suddenly grows up to real size and eats your face. I wish for a better PC.
You get your better pc, but it immediately crashes due to the amount of builds on buildcraftia, not alowing you to play it ever again. I wish for a version of buildcraftia on counsel minecraft.
You get a version of buildcraftia on counsel minecraft, but a day later it's like Minecraft is a ghost town and only 2 people play on it. I wish for magic
You get magic, but sadly its penguin magic which can only be used by penguins I wish for something to eat
You get your food, but you them you get a stomach ache. I wish for a version of pocket edition minecraft with buildcraftia on it
