Off To Vegas
A man comes home after a long day at work and walks into the bedroom to find his wife packing her bags. "What are you doing? Where are you going?" he asks. She looks at him and says' "I'm leaving you and going to Vegas. I heard that a woman can make $400 a night there having sex."
After staring at his wife in disbelief for a moment, the man starts packing a suitcase of his own. "What are you doing? Where are you going?" the wife asks.
The man looks at her with a smile and says, "I'm going with you. I'd like to see how you're going to live off of $800 a year."
