Robert came home from work one day to find his wife on the front porch with her bags packed. "Just where the heck do you think you're going!", Asked Robert. "I'm going to Nairobi", said the wife, "I just found out I can get 4000 a night for what I give you for free!" "Robert said, "Wait a minute!", and then ran inside the house only to come back a few minutes later with his suitcases in hand. "Where the heck are you going?", said the wife. Robert said, "I want to see how you're gonna live on 8000 a year!"
