A blind guy on a bar stool shouts to the bartender, "Wanna hear a blonde joke?" In a hushed voice, the guy next to him says, “Before you tell that joke, you should know something. Our bartender is blonde, the bouncer is blonde. I’m a six foot tall, 200 lb black belt. The guy sitting next to me is six foot two, weighs 225, and he’s a rugby player. The fella to your right is six foot five, pushing 300, and he’s a wrestler. Each one of us is blonde. Think about it, Mister. Do you still wanna tell that joke?" The blind guy says, “Nah, not if I’m gonna have to explain it five times."

U.S. Naval Observatory

In 1842, the U.S. Naval Observatory was authorised by an act of Congress, one of the oldest scientific agencies in the U.S. James Melville Gilliss (1811-1865) is considered its founder, who in 1842 he secured the Congressional appropriation for the Depot of Charts and Instruments (est. 1830) to become the Naval Observatory. Its primary task was to care for the Navy's charts, navigational instruments and chronometers, which were calibrated by timing the transit of stars across the meridian. Initially located at Foggy Bottom, the observatory moved in 1893 to its present facility in Washington, DC. Gillis visited Europe to procure instruments, and the books that formed the core of the Naval Observatory Library. Matthew Fontaine Maury was the first director, followed by Gillis (1861-65).«[Image: domed portion of Foggy Bottom building, showing mast on which a ball dropped at noon as a visual signalofthe time.
