Good wishes aren't always good wishes

Ok, but then the zombie apocalypse happens, so...

I wish that pigs could fly, so that every time people say "when pigs fly" they could be proven wrong
 
Granted, but you prank call someone who is the master of hunting down prank callers. He hunts you down and kills you.


I wish that in no unspecific way, that any part of no part of such wish will be come untrue and impossibly non-dangerous, that I wish not for no un-possibility of getting cake later on.
 
Granted, but you get tired of being a kid and always talked down to, so you kill yourself

I wish people didn't kill themselves all the time
