A man was seen fleeing down the hall of the hospital just before his operation.
"What's the matter?" he was asked.
He said, "I heard the nurse say, 'It's a very simple operation, don't worry, I'm sure it will be all right.'"
"She was just trying to comfort you, what's so frightening about that?"
"She wasn't talking to me. She was talking to the doctor."

Telephone exchange

In 1891, Almon B. Strowger was issued a U.S. patent for his electromechanical switch to automate a telephone exchange (No. 447,918). Strowger did not invent the idea of automatic switching (it was first invented in 1879 by Connolly and McTigthe) but Strowger was the first to put it to effective use. His selector used electromagnets and pawls to move a wiper (with contacts on the end) vertically and around a bank of many other contacts, able to make a connection with any one of them. Strowger formed his company, Strowger Automatic Telephone Exchange, in Oct 1891.
