A man is at work one day when...

A man is at work one day when he notices that his co-worker is wearing an earring.
This man knows his co-worker to be a normally conservative fellow, and is curious about his sudden change in "fashion sense."
The man walks up to him and says, "I didn't know you were into earrings."
"Don't make such a big deal out of this, it's only an earring," he replies sheepishly.
His friend falls silent for a few minutes, but then his curiosity prods him to say, "So, how long have you been wearing one?"
"Ever since my wife found it in my truck..."

Automatic telephone exchange

In 1892, the first automatic telephone exchange, using the switching device invented by Almon B. Strowger, (born 1839) opened to the public in LaPorte, Indiana, with about seventy-five subscribers. A considerable amount of ceremony was attached to the affair, with a special train run from Chicago and a brass band on hand to greet the guests. This early system did not use a dial to enter the desired number. Instead, using three keys, one for each digit of a three-digit number, a subscriber pressed each key the appropriate number of times for each digit. The first dial phones (with projecting vanes instead of holes) was used in Milwaukee's City Hall (1896).* In the UK, the very first Strowger exchange opened at Epsom in Surrey in 1912.
