The local news station was interviewing an eighty-year-old lady

The local news station was interviewing an eighty-year-old lady because she had just gotten married for the fourth time. 
The interviewer asked her questions about her life, about what it felt like to be marrying again at eighty, then about her new husband's occupation.. "He's a funeral director," she answered. 
'Interesting,' the newsman thought... 
He then asked her if she wouldn't mind telling him a little about her first three husbands and what they did for a living. She paused for a few moments, needing time to reflect on all those years. After a short time, a smile came to her face and she answered proudly, explaining that she had first married a banker when she was in her twenties, then a circus ringmaster when in her forties, and a preacher when in her sixties, and now, in her eighties, a funeral director. 
The interviewer looked at her, quite astonished, and asked why she had married four men with such diverse careers. 
She smiled and explained, "I married one for the money, two for the show, three to get ready, and four to go."
