Good doggie

One fall day Bill was out raking leaves when he noticed a hearse slowly drive by. Following the first hearse was a second hearse, which was followed by a man walking solemnly along, followed by a dog, and then about 200 men walking in single file.

Intrigued, Bill went up to the man following the second hearse and asked him who was in the first hearse.

"My wife," the man replied.

"I'm sorry," said Bill. "What happened to her?"

"My dog bit her and she died."

Bill then asked the man who was in the second hearse. The man replied, "My mother-in-law. My dog bit her and she died as well."

Bill thought about this for a while. He finally asked the man, "Can I borrow your dog?"

To which the man replied, "Get in line."

Nobel's first patent

In 1863, Alfred Nobel was granted his first patent, a Swedish patent for the preparation of nitroglycerin. The end of the Crimean War (1856) brought bankruptcy for his father, Immanuel Nobel, whose factory manufactured war materiel. Studying chemistry, Alfred learned of the powerful new explosive, nitroclycerine. Around 1860, Alfred conducted repeated experiments involving great risks. He succeeded in manufacturing sufficient quantities of nitroglycerine without any mishaps. His father had been making similar experiments, but with less success. When his father realized his son's greater discoveries, he assisted Alfred patent the explosive that he aptly called "blasting oil." Later, in 1868, Nobel patented dynamite as a form for safer handling.
