An artist tried to concentrate on his painting, but the attraction he felt for his nude model finally became irresistible. He threw down his palette, took her in his arms and kissed her. She pushed him away. “Maybe your other models let you kiss them,” she said, “but I’m not that kind of girl!” “Actually, I’ve never tried to kiss any of my models before,” he protested. “Really?” she asked, softening. “How many models have there been?” “Four so far,” he replied, thinking back. “A jug, two apples and a vase.”
