Here we have natural selection at its finest, our favorite clones, The Hinkley Triplets. Up front is Darlean, she's a proofreader; one row back is Darleen, she checks for grammar and context; one more row back is Darlene, she checks the arithmetic and financials; way back and further right is Darline, the youngest, and doesn't do much work at all, but she makes everyone think that she does. Each in turn is the apple of Poppa Hinkley's eye.
