Levi's patented

In 1873, Jacob W Davis of Reno, Nevada, received a U.S. patent (No.139,121) on a rivet process for strengthening the pocket openings of canvas pants. He assigned the patent to himself and Levi Strauss, as his business partner. Jacob Davis was in charge of manufacturing when Levi Strauss & Co. opened its two San Francisco factories. Sometime during 1873, the first riveted clothing was made and sold. (The exact date is unknown; the company's historic records were lost in the 1906 San Francisco earthquake and fire.) For nearly 20 years, Levi Strauss & Co. was the only company making riveted clothing, until the patent expired around 1891. Thereafter, dozens of garment manufacturers began to imitate the original riveted clothing.

The Sign

A boss was complaining in a staff meeting the other day that he wasn't getting any respect. Later that morning he went to a local sign shop and bought a small sign that read, "I'm the Boss". He then taped it to his office door.
Later that day when he returned from lunch, he found that someone had taped a note to the sign that said. "Your wife called, she wants her sign back!"
