An old blind cowboy wanders in

An old blind cowboy wanders into an all-girl biker bar by mistake…
He finds his way to a bar stool and orders a shot of Jack Daniels.
After sitting there for a while, he yells to the bartender, ‘Hey, you wanna hear a blonde joke?’
The bar immediately falls absolutely silent.
In a very deep, husky voice, the woman next to him says, ‘Before you tell that joke, Cowboy, I think it is only fair, given that you are blind, that you should know five things:
The bartender is a blonde girl with a baseball bat.
The bouncer is a blonde girl with a ‘Billy-Club’.
I’m a 6-foot tall, 175-pound blonde woman with a black belt in karate.
The woman sitting next to me is blonde and a professional weight lifter.
The lady to your right is blonde and a professional wrestler.
‘Now, think about it seriously, Cowboy... Do you still wanna tell that blonde joke?’
The blind cowboy thinks for a second, shakes his head and mutters,
‘No...not if I’m gonna have to explain it five times...’

Michael Idvorsky Pupin

Born 4 Oct 1858; died 12 Mar 1935 at age 76. Serbian-American physicist who devised a means of greatly extending the range of long-distance telephone communication by placing loading coils (of wire) at predetermined intervals along the transmitting wire. His parents were illiterate, but they encouraged his education. Pupin became an instructor in mathematical physics (1890) at Columbia University, New York City. In 1986, he discovered that atoms struck by X rays emit secondary X-ray radiation. He also invented a means for taking short-exposure X-ray photographs. The Bell Telephone Company, in 1901, acquired the patent for his invention for long-distance telephony. Pupin won a Pulitzer Prize (1924) for his autobiographical work, From Immigrant to Inventor (1923).
