You call in the young man and tell him that he cannot marry your daughter unless he improves his station in life. He takes you at his word and forthwith makes a great deal of money by selling a potion that restores virility. Satisfied, you give your blessing to their marriage.

A few years after the wedding you find that amatory powress is flagging. You consult with your son-in-law and ask him for a supply of the potion. He warns you that continued use may affect the mind. Do you decide not to take that chance or do you decide to risk madness?
