The Box
One day long ago, a man and woman got married. The man told the woman that there would always be a box under the bed but to never look into it. So they were married for 40 years and the woman never looked in the box. On the morning of their 40th anniversary, the wife looked in the box. In the box, there was about 300 dollars in small bills, and 3 empty beer bottles. At dinner that evening, the woman just had to ask. So she did, she asked "what are those beer bottles for, you know, in the box under the bed?" The man said, oh no, you looked. OK, Every time I've been unfaithful to you, I chugged a beer and put it in the box.
The wife says, well for forty years, that's not so bad. At night, the woman was having a bad night, she could not get to sleep, something was bugging her. Then she remembered. She shook awake her husband and asked, what was the money for, though. The guy says, what? The lady says, you know, the money in the box.
The guy says, well, every time the box filled up, I took it in and got money for the bottles.

Surgery bookIn 1575, printing of Ambroise Paré's book Oeuvres Complètes (Complete Works) was finished, but its publication was opposed by establishment physicians. His previous texts on surgery had popularized a new way to treat gunshot wounds without cauterisation, reintroduced the ligature in amputation, and improved midwifery techniques. These many writings were gathered together in this one new volume, which spread his teachings throughout the world. It remained in print for a century and ran to thirteen editions. He wrote in French instead of Latin with practical, common sense so that many barber-surgeons, who (like Paré) were unable to interpret Latin, had access to medical knowledge otherwise unavailable from Latin texts. |
