Too Much Hunting
Saturday morning I got up early, put on my long johns, dressed quietly, made my lunch, grabbed my shotgun and the dog, slipped quietly into the garage to load the truck, and proceeded to back out into a torrential downpour.
There was snow mixed with the rain, and the wind was blowing 50 mph. I pulled back into the garage, turned on the radio, and discovered that the weather would be bad throughout the day.
I went back into the house, quietly undressed, and slipped back into bed. There I cuddled up to my wife's back, now with a different anticipation, and whispered, "The weather out there is terrible."
She sleepily replied, "Can you believe my stupid husband is out hunting in that sh*t?"

Albert NeisserDied 30 Jul 1916 at age 61 (born 22 Jan 1855).Albert Ludwig Sigesmund Neisser was a German physician who specialized in dermatology and venereal diseases. He discovered gonococcus (1879), the small bacterium that causes gonorrhea. In Norway, he examined patients afflicted with leprosy and demonstrated the existence of the bacillus causing the disease (1879). He was the first to make the connection clear between it and the disease. In his studies of syphilis, he failed to find a successful innoculation against the disease, and may even have spread it instead. |
