Skinny Dippers

Ron, an elderly man in Australia, had owned a large farm for several years. He had a large pond at the back.
It was properly shaped for swimming, so he fixed it up nice with picnic tables, horseshoe courts, and some orange and lime trees.

One evening the old farmer decided to go down to the pond, as he hadn't been there for a while, and look it over.
He grabbed a five-gallon bucket to bring back some fruit. As he neared the pond, he heard voices shouting and laughing with glee.

As he came closer, he saw it was a bunch of young women skinny-dipping in his pond. He made the women aware of his presence, and they all went to the deep end.
One of the women shouted to him, "We're not coming out until you leave!"

Ron frowned, "I didn't come down here to watch you ladies swim naked or make you get out of the pond naked."
Holding the bucket up Ron said, "I'm here to feed the alligator."

Robert F. Furchgott

Died 19 May 2009 at age 92 (born 4 Jun 1916).Robert Francis Furchgott was an American pharmacologist who shared (with Louis J. Ignarro and Ferid Murad) the 1998 Nobel Prize in Physiology or Medicine for the discovery that nitric oxide (NO) acts as a signaling molecule in the cardiovascular system. Their combined work uncovered an entirely new mechanism by which blood vessels in the body relax and widen. Nitric oxide (NO), produced by one cell, acts by penetrating membranes and regulating the function of another cell. Nerves and hormones are well known as signal carriers, but this discovery was a totally new signaling principle in a biological system.
