Peanuts

A tour bus driver is driving with a bus load of seniors down a highway when he is tapped on his shoulder by a little old lady. She offers him a handful of peanuts, which he gratefully munches up. After about 15 minutes, she taps him on his shoulder again and she hands him another handful of peanuts. She repeats this gesture about five more times. When she is about to hand him another batch again he asks the little old lady, " Why then don't you eat the peanuts yourself?".
"We can't chew them because we've no teeth," she replied.
The puzzled driver asks, "Why do you buy them then?"
The old lady replied, "We just love the chocolate around them."

Edison patent

In 1882, Thomas A. Edison was issued a patent for an improvement to the telephone (No. 252,442). It described a carbon microphone. Finely divided conducting material, such as carbon, between metal cups mounted on arms is attached to the mouthpiece diaphragm. As sound waves directed through the mouthpiece move the diaphragm, the arms change the pressure on the carbon button which in turn varies an electric current passing through the carbon button. Changes in the current correspond to the pitch and amplitude of the sound. One arm conducts the electrical current to the carbon button, and the the other from it.
