How do you make impossible wishes come true?

By definition you cannot

Put three candles in the highest place you have at home, inside a plate with sugar all around the candles. Light the candles. Ask for three wishes to the angels ST. RAFAEL, ST. MICHAEL, and ST. GABRIEL. Ask one wish for business, one wish for love, and one impossible wish. Publish this spell on the third day after you requested the wishes (by mailing it to another person, posting it to a usenet newsgroup, or announcing your thanks to the saints in a newspaper classified ad) and see what happens on the fourth day...
