A group of third, fourth and fifth graders accompanied by two female teachers went on a field trip to the local racetrack to learn about thoroughbred horses and the supporting industry.
During the tour some of the children wanted to go to the toilet so it was decided that the girls would go with one teacher and the boys would go with the other.
As the teacher assigned to the boys waited outside the men's toilet, one of the boys came out and told her he couldn't reach the urinal. Having no choice, she went inside and began hoisting the little boys up by their armpits, one by one.
As she lifted one, she couldn't help but notice that he was unusually well endowed for an elementary school child.
"I guess you must be in the fifth," she said.
"No ma'am," he replied, "I'm in the seventh, riding Silver Arrow. Thanks for the lift anyhow."

Giovanni Virginio Schiaparelli

Died 4 Jul 1910 at age 75 (born 14 Mar 1835).Italian astronomer who is remembered for his observations of Mars over seven oppositions and named the "seas" and "continents". In 1877, he saw on the surface of the planet Mars the markings that he called canali (channels), later misinterpreted as "canals." He made extensive studies, both observational and theoretical, of comets, determining from the shapes of their tails that there was a repulsive force from the sun. He showed that meteor swarms travel through space in cometary orbits. He explained the regular meteor showers as the result of the dissolution of comets and proved it for the Perseids. He suggested that Mercury and Venus rotate on their axes, discovered the asteroid Hesperia (1861) and was a major observer of double stars.
