### Sharing Everything

A young man saw an elderly couple sitting down to lunch at McDonald's. He noticed that they had ordered one meal, and an extra drink cup. As he watched, the gentleman carefully divided the hamburger in half, then counted out the fries, one for him, one for her, until each had half of them. Then he poured half of the soft drink into the extra cup and set that in front of his wife. The old man then began to eat, and his wife sat watching, with her hands folded in her lap.
The young man decided to ask if they would allow him to purchase another meal for them so that they didn't have to split theirs.
The old gentleman said, "Oh no. We've been married 50 years, and everything has always been and will always be shared, 50/50."
The young man then asked the wife if she was going to eat, and she replied, "It's his turn with the teeth."

### Xerography

In 1938, xerography was demonstrated by Chester F. Carlson. With his assistant, Otto Kornei, Carlson used a sulphur coating on a zinc plate, vigorously rubbed with a handkerchief to apply an electrostatic charge. A glass slide was prepared using India ink to write "10-22-38 ASTORIA," then laid on the sulphur surface in a darkened room. After illuminating them with a bright incandescent lamp for a few seconds, the slide was removed. When lycopodium powder was sprinkled on the sulphur surface and blown off, there remained a near-perfect image of the writing. Permanent copies were made by transferring the powder images to wax paper and heating the sheets to melt the wax. Xerox is a term coming from "xerography" which means dry writing and is a trademark.
