The barber's client looked depressed, so the barber told him, "Cheer up. I knew a guy who owed $5,000 he couldn't pay. He drove his vehicle to the edge of a cliff, where he sat for over an hour. A group of concerned citizens heard about his problem and passed a hat around. Relieved, the man pulled back from the cliff's edge."
"Incredible," said the client. "Who were these kind people?"
"The passengers on the bus."

Toothbrush

In 1498, the bristle toothbrush was invented in China. Coarse hairs taken from the back of a hog's neck were used for the bristles, attached at right angles to a bone or bamboo handle (similar to the modern type). The best bristles came from hogs raised in the colder climates of China and Siberia, where the animals grew stouter and firmer hair. Since 3000 BC, ancient civilizations had been cleaning teeth with a "chew-stick" by using a thin twig with a frayed end.[Note: A 17th century Chinese encyclopedia (source) claims that the year was 1498 for the invention of the toothbrush but the date 26 June needs a confirming source.]
