A woman was having a daytime a...

A woman was having a daytime affair while her husband was at work. One wet and lusty day she was in bed with her boyfriend when, to her horror, she heard her husband's car pull into the driveway.
"Hurry! Grab your clothes," she yelled to her lover, "and jump out the window. My husband's home early!"
"I can't jump out the window!" came the strangled reply from beneath the sheets. "It's raining out there!"
"If my husband catches us in here, he'll kill us both!" she replied. "He's got a very quick temper and a very large gun! The rain is the least of your problems!"
So the boyfriend scoots out of bed, grabs his clothes and jumps out the window! As he began running down the street in the pouring rain, he quickly discovered he had run right into the middle of the town's annual marathon.
So he started running along beside the others, about 300 of them. Being naked, with his clothes tucked under his arm, he tried to "blend in" as best he could. It wasn't that effective!
After a little while, a small group of runners, who had been studying him with some curiosity, jogged closer.
"Do you always run in the nude?" one asked.
"Oh, yes!" he replied, gasping for air. "It feels so wonderfully free having the air blow over all your skin while you're running."
Another runner moved alongside. "Do you always run carrying your clothes with you under your arm?"
"Oh, yes!" our friend answered breathlessly. "That way I can get dressed right at the end of the run and get in my car to go home!"
Then a third runner cast his eyes a little lower and queried. "Do you always wear a condom when you run?"
"Only when it's raining," he replied.

Michael Faraday

Born 22 Sep 1791; died 25 Aug 1867 at age 75. English physicist and chemist whose many experiments contributed greatly to the understanding of electromagnetism. Although one of the greatest experimentalists, he was largely self-educated. Appointed by Sir Humphry Davy as his assistant at the Royal Institution, Faraday initially concentrated on analytical chemistry, and discovered benzene in 1825. His most important work was in electromagnetism, in which field he demonstrated electromagnetic rotation and discovered electromagnetic induction (the key to the development of the electric dynamo and motor). He also discovered diamagnetism and the laws of electrolysis. He published pioneering papers that led to the practical use of electricity, and he advocated the use of electric light in lighthouses.«
