When Bob found out he was going to inherit a fortune when his sickly father died, he decided he needed a woman to enjoy it with.  SO one evening he went to a singles bar where he spotted the most beautiful woman he had ever seen.

Her natural beauty took his breath away.  "I may look like just an ordinary man," he said as he approached her, "but in just a week or two my father will die and I'll inherit over 20 million dollars."

Impressed the woman went home with him that evening.

Three days later she became his step-mother.
