It's raining out there!
A woman was having a daytime affair while her husband was at work. One rainy day she was in bed with her boyfriend when, to her horror, she heard her husband's car pull into the driveway.
'Oh my God - Hurry! Grab your clothes and jump out the window. My husband's home early!'
'I can't jump out the window. It's raining out there!'
'If my husband catches us in here, he'll kill us both!' she replied. 'He's got a hot temper and a gun, so 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 ran 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. After a little while a small group of runners who had been watching him with some curiosity, jogged closer.
Do you always run in the nude?' one asked.
'Oh yes!' he replied, gasping in air. 'It feels so wonderfully free!'
Another runner moved a long side. '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 asked, 'Do you always wear a condom when you run?'
'Nope..just when it's raining.'

He followed this by a public demonstration of this method of anesthesia on16 Oct 1846 during an operation performed by Dr. John Collins Warren (1778-1856) at the Massachusetts General Hospital in Boston. The patient, Gilbert Abbott, age 20, had a small superficial tumor removed from beneath the left lower jaw. The suggestion to use ether came from the chemist Charles T. Jackson, (1860-1913). After the success of the public demonstration, the use of ether for painless operations spread quickly to other countries. |
