Number Jokes
A man is sent to prison for the first time. At night, the lights in the cell block are turned off, and his cellmate goes over to the bars and yells, "Number twelve!" The whole cell block breaks out laughing. A few minutes later, somebody else in the cell block yells, "Number four!" Again, the whole cell block breaks out laughing.
The new guy asks his cellmate what's going on. "Well," says the older prisoner, "we've all been in this here prison for so long, we all know the same jokes. So we just yell out the number instead of saying the whole joke."
So the new guy walks up to the bars and yells, "Number twenty-nine!" This time the whole cell block rocks with the loudest laughter, prisoners rolling on the floor laughing hysterically.
When the guffaws die down, the bewildered new guy turns to the older prisoner and asks, "How come you guys were laughing so hard this time?"
"Oh," says the older man wiping tears from his eyes, "we'd never heard that one before."

William Friese-GreeneBorn 7 Sep 1855; died 5 May 1921 at age 65.English photographer and inventor who built and patented an early somewhat practical motion picture camera (21 Jun 1889, No. 10,131). From about 1875, he operated a portrait photography studio. He experimented with motion photography. An early attempt was a camera able to take 10 images per second on a roll of sensitized paper. Later he used celluloid film. He claimed perhaps the first time a film of an actual event was ever projected on a screen - a jerky picture of people and horse-drawn vehicles moving past Hyde Park Corner. Although he held and defended patents, his inventions were less significant than those developed by others. The first functional movie camera is generally credited to Frenchman Etienne-Jules Marey in 1888.« |
