Since we're on the marriage topic, here's one a I just heard.
A man comes home from work one day and sees his wife packing up her suitcases. He asks her where she's going, and she says "I'm leaving you and moving to Las Vegas. I just saw on television that I can make $200 a night doing what I do for you for free."
Suddenly, the husband begins packing his bags, too. The wife asks what he's doing, and he says "I want to see how you're going to live on $400 a year."
