The flower vendor was usually...

The flower vendor was usually an old hand at unloading his last few bunches. Appealing to a businessman on his way home, the vendor said, "How about a nice bunch of roses to surprise your wife?"
"Haven't got a wife," responded the businessman gruffly.
"Then how about some carnations for your girlfriend?" proposed the vendor without missing a beat.
"Haven't got a girlfriend."
"You lucky guy!" The vendor broke into a big smile. "Buy both bunches to celebrate!"

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.
