Vacuum Cleaner Salesman

A little old lady answered a knock on the door one day, only to be confronted by a well-dressed young man carrying a vacuum cleaner. Good morning," said the young man. "If I could take a couple of minutes of your time, I would like to demonstrate the very latest in high-powered vacuum cleaners.
"Go away!" said the old lady. "I haven't got any money!" and she proceeded to close the door..
Quick as a flash, the young man wedged his foot in the door and pushed it wide open. "Don't be too hasty!" he said. "Not until you have at least seen my demonstration." And with that, he emptied a bucket of horse manure onto her hallway carpet. "If this vacuum cleaner does not remove all traces of this horse manure from your carpet, Madam, I will personally eat the remainder."
The old lady stepped back and said, "Well I hope you've got a damned good appetite, because they cut off my electricity this morning.."

Conrad von Gesner

Died 13 Dec 1565 at age 49 (born 26 Mar 1516).Swiss physician, naturalist, and encyclopedist is best known for his monumental works. Gesner's aim was to survey all the world's recorded knowledge. His books included systematic compilations of information on animals and plants. Elaborately illustrated , Historiae animalium comprised five volumes, the first appearing in 1551, each covering a portion of the animal kingdom. Gesner's pictures made his works both more appealing and less ambiguous. Although he listed all the animals known in Europe, he had no idea of the relationships one animal to another. Yet, in Historica Plantarum (History of Plants), published two centuries after his death, he was the first to recognize that similar species could be grouped to form genera.Image: The first known illustration of a lead pencil is found in Gesner's book on fossils (1565). [Name sometimes spelled as 'Konrad'.]
