A man is walking in the forest, when he comes across a witch, who says to him "And now it is time for your third and final wish."
He says - "What? Who are you? What do you mean third wish?"
"Well," she said, "Your second wish was that your first wish be totally undone, and that all knowledge of it be forever expunged from your memory."
"Wow," says the man. "That must have been a really bad wish. I'll have to make sure I wish for something better now, something a little wiser..." The man thought for a while, then said "I've got it! Ok, here's my wish. I wish to know my true nature."
"Very well," said the witch with a shrug, as she granted the wish then disappeared into a puff of smoke. "Although it's funny - that was your first wish."
