Bubba and Junior were standing...

Bubba and Junior were standing at the base of a flagpole, looking up.
A woman walked by and asked what they were doing. "We're supposed to find the height of the flagpole," said Bubba, "but we don't have a ladder."
The woman took a wrench from her purse, loosened a few bolts, and laid the pole down. Then she took a tape measure from her pocket, took a measurement, announced, "Eighteen feet, six inches," and walked away.
Junior shook his head and laughed. "Ain't that just like a dumb blonde! We ask for the height, and she gives us the length!"

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.
