A man came home from work one day to find his wife sitting on the front porch with her bags packed. He asked her where she was going and she replied, "I'm going to Las Vegas." He asked her why she was going. She told him, "I just found out that as a woman I can make $400 a night doing what I give you for free." He went into the house, packed his bags and returned to the porch. His wife said, "And just where do you think you are going?" "I''m going too!" he replied. "Why?" she asked. "I want to see how you are going to live on $800 a year!"
