Two Elderly Gentlemen

Two elderly gentlemen, who had been without sex for several years, decided they needed to visit a cat-house for some tail..... When they arrived, the madam took one look at them and decided she wasn't going to waste any of her girls on these two old men.
So she used "blow-up" dolls instead. She put the dolls in each man's room and left them to their business. After the two men were finished, they started walking home and began to talking. The first man said, "I think the girl I had was dead. She never moved, talked or even groaned... how was it for you?"
The second man replied, "I think mine was a witch. When I nibbled on her breast..... she farted and flew out the window!"

Lorenzo Bellini

Born 3 Sep 1643; died 8 Jan 1704 at age 60.Italian physician and anatomist who described the collecting, or excretory, tubules of the kidney, known as Bellini's ducts (tubules). Bellini is considered a founder of Italian iatromechanism, a pioneer in applying mechanical philosophy to the functions of the human body. His early interests were anatomy and physiology. The first essay he published, Exercitatio anatomica de usu renum (1662), contains his anatomical discovery that in the supposedly unorganized parenchyma there is a complicated structure composed of fibers, open spaces, and densely packed tubules opening into the pelvis of the kidney. His further publications extended his effort to explain all important physiological phenomena according to the law of mechanics. (Several discoveries previously ascribed to Lorenzo Bellini were made earlier by Bartolomeo Eustachi.)Image: kidney structure as drawn by Bellini
