"Planning Ahead" joke

A woman decided to have her portrait painted. She told the artist, "Paint me with diamond rings, a diamond necklace, emerald bracelets, a ruby broach, and gold Rolex.""But you are not wearing any of those things," he replied."I know," she said. "It's in case I should die before my husband. I'm sure he will remarry right away, and I want his new wife to go crazy looking for the jewelry."
