I corrupt your wish, so that it isn't corrupted. Since it isn't corrupted, it CAN'T be corrupted. But since it can't be corrupted, it can't be corrupted to become immune to corruption. Since it isn't immune to corruption, it is, in fact, corrupted so that is isn't corrupted. But this gives it immunity to corruption, so that it can't be corrupted to have said immunity. (Enjoy mulling that over for awhile.)
Having been promptly proven wrong, I instead rescind my previous wish and wish for a PIKACHU (since they DO have thumbs) who plays Smash Brothers with me.
