Vegas

The husband walks into his bedroom, where he sees his wife packing a suitcase.

"Where are you going?" he asks.

She replies. "I am moving to Las Vegas. I hear the girls there get $400 a night for what I've been doing for you for free."

Later, on her way out, the wife enters the bedroom to see her husband packing his suitcase.

When she asked him where he was going, he replied "Las Vegas. I want to see how you can live on $800 a year."
