From the entertaining “My Secret Fantasies“, this old joke dressed up as an anecdote:

Another friend of ours, K.C., went out with us, and we met a woman that calls herself a white witch. He may not understand, but he asked her if she can remove a curse that has been with him for 8 years now. The witch said to him, “Maybe, but you will have to tell me the exact words that were used to put the curse on you.” K.C. said, “I now pronounce you man and wife.”

Sorry, my friend, but a white witch isn’t gonna do the trick. K.C., you need lawyer rituals and there will be sacrifices involved.
