A young woman said to her doctor, 'You have to help me, I hurt all over.' 'What do you mean?' said the doctor. The woman touched her right knee with her index finger and yelled,'Ow, that hurts.' Then she touched her left cheek and again yelled, 'Ouch! That hurts, too.' Then she touched her right earlobe. 'Ow, even THAT hurts.' The doctor asked the woman, 'Are you a natural blonde?' 'Why yes,' she said. 'I thought so,' said the doctor. 'You have a sprained finger.'

Steam shovel

In 1839, Mr. William Smith Otis, civil engineer of Philadelphia, Penn., was issued a U.S. patent for the steam shovel (No. 1,089) for excavating and removing earth from railroads or canals. The patent drawing showed the crane mounted on a carriage or railroad car. A load of earth could be taken up by the scraper, raised by the crane and turned to be dumped, such as in railcars, and released. The patent described how a steam engine of a kind already in ordinary use, was installed with a power control mechanism for the crane, and a system of pulleys to move its arms and bucket. It could move about 380 cubic metres of earth a day, with its 1.1 cubic metre capacity shovel and 180° slewing wooden jib. It was first used on the Western Railroad in Mass.[Image: Steam shovel built by John Souther in his Globe Locomotive Works in South Boston, Mass. shown behind railcars it is loading with gravel (1857).]
