A man walks into a pharmacy and wanders up and down the aisles. The sales girl notices him and asks him if she can help him. He answers that he is looking for a box of tampons for his wife. She directs him down the correct aisle.
A few minutes later, he deposits a huge bag of cottonballs and a ball of string on the counter.
The sales girl says, confused, "Sir, I thought you were looking for some tampons for your wife?"
He answers, "You see, it's like this, yesterday, I sent my wife to the store to get me a carton of cigarettes, and she came back with a tin of tobacco and some rolling papers; cause it's so-o-o much cheaper. So, I figure if I have to roll my own... so does she."

### William Gilbert

Died 10 Dec 1603 at age 59 (born 24 May 1544). English scientist, the “father of electrical studies” and a pioneer researcher into magnetism, who spent years investigating magnetic and electrical attractions. Gilbert coined the names of electric attraction, electric force, and magnetic pole. He became the most distinguished man of science in England during the reign of Queen Elizabeth I. Noting that a compass needle not only points north and south, but also dips downward, he thought the Earth acts like a bar magnet. Like Copernicus, he believed the Earth rotates on its axis, and that the fixed stars were not all at the same distance from the earth. Gilbert thought it was a form of magnetism that held planets in their orbits.[EB gives death date as 10 Dec (Old Style 30 Nov) 1603.]
