Lawyers Get Robbed

Two lawyers are in a bank, when, suddenly, armed robbers burst in.
While several of the robbers take the money from the tellers, others line the customers, including the lawyers, up against a wall, and proceed to take their wallets, watches, etc. While this is going on lawyer number one jams something in lawyer number two's hand.
Without looking down, lawyer number two whispers, "What is this?" to which lawyer number one replies, "It's that $50 I owe you."

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.
