A wealthy matron is so proud of a valuable antique vase that she decides to have her bedroom painted the same color as the vase. Several painters try to match the shade, but none comes close enough to satisfy the eccentric woman.
Eventually, a painter approaches who is confident he can mix the proper color. The woman is pleased with the result, and the painter becomes famous.
Years later, he retires and turns the business over to his son."Dad," says the son, "there's something I've got to know. How did you get those walls to match the vase so perfectly?
"Son," the father replies, "I painted the vase."
