• The invention of the toothbrush has no well defined origin, but the first bristle toothbrush has been discovered in China from the Tang Dynasty (circa A.D. 619–907).  It used hog bristle.  Not quite the same as brushing your teeth with bacon flavored toothpaste, but close.
• A cubic mile of fog is made up of 56,000 gallons of water.
• The word coward original comes from Latin word couda, meaning "tail".
