Low Bridge

A truck driver was driving along on the freeway. He passed a sign that said “low bridge ahead.”
Before he knew it, the bridge was right ahead of him and he got stuck under the bridge. You could say that he got a rock solid “Trucker's Wedgie.”
Cars were backed up for miles.
Finally, a police car pulled up. The cop got out of his car and walked around to the truck driver, put his hands on his hips and said, “Got stuck, huh?”
The truck driver said, “No officer,… I was delivering this bridge and ran out of gas!”

Edison phonograph

In 1877, Thomas Alva Edison, though this date is often given as the date of a finished model of his first phonograph, may have actually only made a sketch. Some correspondence in Sep 1877 suggests Edison was at work on his ideas for what became his cylinder phonograph, though construction of a working model may not have begun until 4 Dec, according to the diary of one of Edison's aides. Indeed, Edison did not file for the patent until 24 Dec 1877. The idea came to him while working on a telegraph transmitter, when he noticed that when the tape of the machine was played at high speed, it gave off a noise resembling spoken words. After experimenting with a needle attached to the diaphragm of a telephone receiver to prick paper tape to record a message, his idea evolved to using a stylus on a tinfoil cylinder.«[Image: Sketch dated 20 Nov 1877 given to machinist John Kruesi to make the world's first cylinder phonograph.]
